[PATCH 0/6] ASoC: rt5670/Intel: Add support for Bay Trail CR / Dell Venue 10 Pro 5055 tablet
by Hans de Goede 02 Apr '21

02 Apr '21

Hi All, Here is a patch series to enable sound on the Dell Venue 10 Pro 5055 tablet this series also includes 2 generic improvements to rt5672 support: 1. Add support for boards using Bay Trail CR (SSP0) in combination with a rt5672 codec 2. Set the card's components string based on the DMI info, so that we don't need to duplicate the DMI quirks in userspace (in the UCM profile) I've a patch to add support for the components string to the UCM profile for these boards available here: https://github.com/jwrdegoede/alsa-ucm-conf/commit/fedacc2bdc530b6febac665d… I will submit this upstream once the kernel side has landed.

[PATCH] ASoC: fsl_esai: Fix TDM slot setup for I2S mode
by Alexander Shiyan 02 Apr '21

02 Apr '21

When using the driver in I2S TDM mode, the fsl_esai_startup() function rewrites the number of slots previously set by the fsl_esai_set_dai_tdm_slot() function to 2. To fix this, let's use the saved slot count value or, if TDM is not used and the number of slots is not set, the driver will use the default value (2), which is set by fsl_esai_probe().

[PATCH 0/2] soundwire: bus: handle errors in clock stop/start sequences
by Bard Liao 02 Apr '21

02 Apr '21

If a device lost sync and can no longer ACK a command, it may not be able to enter a lower-power state but it will still be able to resync when the clock restarts. In those cases, we want to continue with the clock stop sequence. This patch modifies the behavior when -ENODATA is received, with the error level demoted to a dev_dbg() since it's a recoverable issue. For consistency the log messages are also modified to be unique and self-explanatory, and missing logs are also added on clock stop exit.

[PATCH] Fixing most Roland-related devices' USB audio
by Lucas 01 Apr '21

01 Apr '21

At the risk of being redundant, I'm resending this with a simpler "[PATCH]" subject to reach a broader audience, since no comment has been made yet: TLDR? Please just glance at the patch at the end and include it in the kernel. :) Some days ago, I found this excellent informational post, and that Mike Oliphant's patch is in mainline now: http://blog.nostatic.org/2020/01/getting-boss-gt-1-effects-processor-to.html Since I was fairly certain it applies to the Roland devices I own, I added my USB IDs. Wonderfully, now USB audio capture seems to be working perfectly from the three devices I can test: the Boutique D-05, INTEGRA-7, & R-26! (The previously asserted VG-99 didn't need to be included in the patch for it to work.) I've also tested all three for playback capability, since that's implied when a device is using implicit feedback, which I hadn't realized the first time around. Anyway, they all seem to be working as expected for playback too. There are two caveats for playback, though: 1. The INTEGRA-7 won't output playback in any mode other than its "44.1 [kHz]" setting, though capture works with all of its Sample Rate possibilities. I think this is imposed by the hardware itself, and hence isn't a glitch. 2. The D-05's analog outputs aren't as clean as the other two devices, with little quiet occasional clicks sounding something like dust on an LP record's play. Possibly that can be due to it having only 1/8" mini-jack connections, but I suspect something more driver-related as It's not noticed during use as a synthesizer. Its firmware version is "1.02(1033)," so not up-to-date which may mean it's just the hardware itself, but I've decided not to risk any changes with it yet. If I knew I could revert it, that would be another story. Also its USB captures, play perfectly & cleanly on my usual sound device, the Edirol UA-4FX. You may know this, as the detection of these devices shows partial compatibility with the existing kernel, but here are the commands I've had to use for their sample formats: Boutique D-05: arecord -D hw:Boutique -f S32_LE -c 2 -r 96000 ./file.wav aplay -D hw:Boutique -f S32_LE -c 2 -r 96000 ./file.wav INTEGRA-7: arecord -D hw:INTEGRA7 -f S32_LE -c 2 -r 96000 ./file.wav (Then change MENU->SYSTEM->SOUND->Sampling Rate to 44.1 [kHz], otherwise its 96[kHz], and change MENU->SYSTEM->SOUND->Ext Part Source Select to USB AUDIO) arecord -D hw:INTEGRA7 -f S32_LE -c 2 -r 44100 ./file-44100.wav aplay -D hw:INTEGRA7 -f S32_LE -c 2 -r 44100 ./file-44100.wav R-26: (Through its built-in controls, first configure the MENU->AUDIO I/F SETUP->SAMPLE RATE to "96.0 kHz.") arecord -D hw:R26AUDIO -f S32_LE -r 96000 -c 2 ./file.wav aplay -D hw:R26AUDIO -f S32_LE -r 96000 -c 2 ./file.wav (Then via use of similar commands, & the "AUDIO I/F" tab on its main screen having both "LOOP BACK" & "DIRECT MONITOR" enabled, I was able to begin a new composite recording, voicing-over what I'd recorded earlier, by playing it back while interjecting - very fun!) The behavior on the vanilla kernel (whether or not "pasuspender -- cat" is running concurrently) follows. For each of these commands, dmesg is bombarded with lines like "[ 4681.162863] usb 2-1.2: Unable to change format on ep #8e: already in use" Boutique D-05: arecord -D hw:Boutique -f S32_LE -r 96000 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo (After a brief timeout, it says this & ends:) arecord: pcm_read:2153: read error: Input/output error aplay -D hw:Boutique -f S32_LE -r 96000 -c 2 ./valid-file.wav Playing WAVE './valid-file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo (After a brief timeout, it says this & ends:) aplay: pcm_write:2061: write error: Input/output error INTEGRA-7: arecord -D hw:INTEGRA7 -f S32_LE -r 96000 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo (After a brief timeout, it says this & ends:) arecord: pcm_read:2153: read error: Input/output error (Then change MENU->SYSTEM->SOUND->Sampling Rate to 44.1 [kHz], otherwise its 96[kHz], and change MENU->SYSTEM->SOUND->Ext Part Source Select to USB AUDIO) arecord -D hw:INTEGRA7 -f S32_LE -r 44100 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 32 bit Little Endian, Rate 44100 Hz, Stereo (After a brief timeout, it says this & ends:) arecord: pcm_read:2153: read error: Input/output error aplay -D hw:INTEGRA7 -f S32_LE -r 44100 -c 2 ./valid-file.wav Playing WAVE './valid-file.wav' : Signed 32 bit Little Endian, Rate 44100 Hz, Stereo (After a brief timeout, it says this & ends:) aplay: pcm_write:2061: write error: Input/output error R-26: arecord -D hw:R26AUDIO -f S32_LE -r 96000 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo (After a brief timeout, it says this & ends:) arecord: pcm_read:2153: read error: Input/output error aplay -D hw:R26AUDIO -f S32_LE -r 96000 -c 2 ./valid-file.wav Playing WAVE './valid-file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo (After a brief timeout, it says this & ends:) aplay: pcm_write:2061: write error: Input/output error I searched a bit for other Roland-related devices people have had USB digital audio issues with over the years, and took the liberty of adding them to the patch too. Likely there are still more that people haven't tried or, at least, queried about issues. I hope this can be added to the mainline kernel, as this support should help many that have struggled. I, certainly, have been hoping somebody would figure this out for quite a while, and even bought a USB through/monitoring device to try to develop it myself (sadly, the software supporting that has its own bugs, so I probably should've just used wireshark). Suffice it to say, I'm quite happy to have this figured out without having had to delve into USB debugging stuff I lack experience with! :) Thanks for any comments or looking into adding this, Lucas Endres The patch follows (I removed my previous VG-99 additions since it already works): diff -Nurp linux-5.11.9.orig/sound/usb/implicit.c linux-5.11.9.roland/sound/usb/implicit.c --- linux-5.11.9.orig/sound/usb/implicit.c 2021-03-24 05:54:19.000000000 -0500 +++ linux-5.11.9.roland/sound/usb/implicit.c 2021-03-30 17:49:08.143196280 -0500 @@ -71,27 +71,87 @@ static const struct snd_usb_implicit_fb_ .ep_num = 0x84, .iface = 0 }, /* MOTU MicroBook II */ /* No quirk for playback but with capture quirk (see below) */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00a6), /* Roland JUNO-G */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00ad), /* Roland SH-201 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00c2), /* Roland SonicCell */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00c4), /* Edirol M-16DX */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00c7), /* Roland V-Synth GT */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00da), /* BOSS GT-10 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00db), /* BOSS GT-10 Guitar Effects Processor */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00dc), /* BOSS GT-10B */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00de), /* Roland Fantom-G */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00f8), /* Roland JUNO Series */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0111), /* Roland GAIA SH-01 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0120), /* Roland OCTA-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0121), /* Roland OCTA-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0123), /* Roland JUNO-Gi */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0127), /* Roland GR-55 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x012b), /* Roland DUO-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x012f), /* Roland QUAD-CAPTURE */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0130), /* BOSS BR-80 */ - IMPLICIT_FB_SKIP_DEV(0x0582, 0x0171), /* BOSS RC-505 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0132), /* Roland TRI-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0138), /* BOSS RC-300 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x013e), /* Roland R-26 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x014d), /* BOSS GT-100 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0150), /* Roland TD-15 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0151), /* Roland TD-11 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0158), /* Roland TD-30 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0159), /* Roland DUO-CAPTURE EX */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x015b), /* Roland INTEGRA-7 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x015d), /* Roland R-88 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0171), /* BOSS RC-505 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x017c), /* Roland TR-8 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0185), /* BOSS GP-10 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0189), /* BOSS GT-100v2 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x01b5), /* Roland Boutique Series Synthesizer */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01d6), /* BOSS GT-1 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01d8), /* BOSS Katana */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01e5), /* BOSS GT-001 */ - IMPLICIT_FB_SKIP_DEV(0x0582, 0x0203), /* BOSS AD-10 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x01ff), /* Roland D-05 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0203), /* BOSS AD-10 */ {} /* terminator */ };

In some cases, SoundWire device ports are statically mapped to Controller ports during design, however there is no way to expose this information to the controller. Controllers like Qualcomm ones use this info to setup static bandwidth parameters for those ports. A generic port allocation is not possible in this cases! This patch adds a new member m_port_map to SoundWire device so that it can populate the static master port map and share it with controller to be able to setup correct bandwidth parameters. As a user of this feature this patchset also adds new bindings for wsa881x smart speaker which has 4 ports which are statically mapped to the 3 output and 1 input port of the controller. Tested it on DB845c and SM8250 MTP. thanks, srini Changes since v3: - updated kernel doc for more clarity on m_port_map Srinivas Kandagatla (5): soundwire: add static port mapping support soundwire: qcom: update port map allocation bit mask soundwire: qcom: add static port map support ASoC: dt-bindings: wsa881x: add bindings for port mapping ASoC: codecs: wsa881x: add static port map support .../bindings/sound/qcom,wsa881x.yaml | 9 ++++++ drivers/soundwire/qcom.c | 31 +++++++++++++++---- include/linux/soundwire/sdw.h | 2 ++ sound/soc/codecs/wsa881x.c | 7 +++++ 4 files changed, 43 insertions(+), 6 deletions(-) -- 2.21.0

[PATCH] soundwire: qcom: wait for fifo space to be available before read/write
by Srinivas Kandagatla 01 Apr '21

01 Apr '21

If we write registers very fast we can endup in a situation where some of the writes will be dropped without any notice. So wait for the fifo space to be available before reading/writing the soundwire registers.

re: ALSA: control - add layer registration routines

Hi, Static analysis on linux-next with Coverity has detected a potential issue in the following commit: commit 3f0638a0333bfdd0549985aa620f2ab69737af47 Author: Jaroslav Kysela <perex(a)perex.cz> Date: Wed Mar 17 18:29:41 2021 +0100 ALSA: control - add layer registration routines The static analysis is as follows: 2072 void snd_ctl_disconnect_layer(struct snd_ctl_layer_ops *lops) 2073 { 2074 struct snd_ctl_layer_ops *lops2, *prev_lops2; 2075 2076 down_write(&snd_ctl_layer_rwsem); assignment: Assigning: prev_lops2 = NULL. 2077 for (lops2 = snd_ctl_layer, prev_lops2 = NULL; lops2; lops2 = lops2->next) 2078 if (lops2 == lops) { null: At condition prev_lops2, the value of prev_lops2 must be NULL. dead_error_condition: The condition !prev_lops2 must be true. 2079 if (!prev_lops2) 2080 snd_ctl_layer = lops->next; 2081 else 'Constant' variable guards dead code (DEADCODE) dead_error_line: Execution cannot reach this statement: prev_lops2->next = lops->next;. Local variable prev_lops2 is assigned only once, to a constant value, making it effectively constant throughout its scope. If this is not the intent, examine the logic to see if there is a missing assignment that would make prev_lops2 not remain constant. 2082 prev_lops2->next = lops->next; 2083 break; 2084 } 2085 up_write(&snd_ctl_layer_rwsem); 2086 } I couldn't quite figure out the original intent of the prev_lops use, so I'd thought I'd report this issue as the code does look incorrect.

(gdb) ``` So the error seems to happen in `libsamplerate.so` Switching the sync method to "SIMPLE" prevents the error from happening as alsaloop doesn't seem to make use of libsamplerate in this case. The following modes run without failing but don't give the desired results: ``` pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 0 # SYNC_TYPE_NONE pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 1 # SYNC_TYPE_SIMPLE pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 2 # SYNC_TYPE_CAPTRATESHIFT pi@pi-snapserver:~ $ alsaloop -C hw:2,0 -P hw:3,0 -S 3 # SYNC_TYPE_PLAYRATESHIFT ``` Only `SYNC_TYPE_SAMPLERATE` and `SYNC_TYPE_AUTO` (which selects SYNC_TYPE_SAMPLERATE) fail. The modes `SYNC_TYPE_NONE` and `SYNC_TYPE_SIMPLE` don't crash for me, but they don't work and result in increasing latency until the fifos reset. (Which is another issue I guess) Issue URL : https://github.com/alsa-project/alsa-utils/issues/85 Repository URL: https://github.com/alsa-project/alsa-utils

[PATCH v2] soundwire: intel: move to auxiliary bus
by Bard Liao 31 Mar '21

31 Mar '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> Now that the auxiliary_bus exists, there's no reason to use platform devices as children of a PCI device any longer. This patch refactors the code by extending a basic auxiliary device with Intel link-specific structures that need to be passed between controller and link levels. This refactoring is much cleaner with no need for cross-pointers between device and link structures. Note that the auxiliary bus API has separate init and add steps, which requires more attention in the error unwinding paths. The main loop needs to deal with kfree() and auxiliary_device_uninit() for the current iteration before jumping to the common label which releases everything allocated in prior iterations.

[PATCH v6 0/9] soundwire: qcom: various improvements
by Srinivas Kandagatla 30 Mar '21

30 Mar '21

Thanks for reviewing v5 of this patchset! During testing SoundWire controller on SM8250 MTP, we found few issues like all the interrupts are not handled, all transport parameters are not read from device tree. Patch to add Auto Enumeration supported by the controller is also part of this series. Other major issue was register read/writes which was interrupt based was an overhead and puts lot of limitation on context it can be used from. With previous approach number of interrupts generated after enumeration are around 130: $ cat /proc/interrupts | grep soundwire 21: 130 0 0 0 0 0 0 0 GICv3 234 Edge soundwire after this patch they are just 3 interrupts $ cat /proc/interrupts | grep soundwire 21: 3 0 0 0 0 0 0 0 GICv3 234 Edge soundwire So this patchset add various improvements to the existing driver to address above issues. Tested it on SM8250 MTP with 2x WSA881x speakers, HeadPhones on WCD938x via lpass-rx-macro and Analog MICs via lpass-tx-macro. Also tested on DragonBoard DB845c with 2xWSA881x speakers. Changes since v5: - Use BIT macro in interrupt routine - add comment for fifo write Srinivas Kandagatla (9): dt-bindings: soundwire: qcom: clarify data port bus parameters soundwire: qcom: add support to missing transport params soundwire: qcom: set continue execution flag for ignored commands soundwire: qcom: start the clock during initialization soundwire: qcom: update register read/write routine soundwire: qcom: add support to new interrupts soundwire: export sdw_compare_devid, sdw_extract_slave_id and sdw_slave_add soundwire: qcom: add auto enumeration support soundwire: qcom: wait for enumeration to be complete in probe .../bindings/soundwire/qcom,sdw.txt | 20 + drivers/soundwire/bus.c | 4 +- drivers/soundwire/qcom.c | 529 ++++++++++++++---- drivers/soundwire/slave.c | 1 + include/linux/soundwire/sdw.h | 2 + 5 files changed, 443 insertions(+), 113 deletions(-) -- 2.21.0

[PATCH] ASoC: q6afe-clocks: fix reprobing of the driver
by Dmitry Baryshkov 30 Mar '21

30 Mar '21

Q6afe-clocks driver can get reprobed. For example if the APR services are restarted after the firmware crash. However currently Q6afe-clocks driver will oops because hw.init will get cleared during first _probe call. Rewrite the driver to fill the clock data at runtime rather than using big static array of clocks.

[PATCH v4 0/6] ALSA: control - add generic LED API
by Jaroslav Kysela 30 Mar '21

30 Mar '21

This patchset tries to resolve the diversity in the audio LED control among the ALSA drivers. A new control layer registration is introduced which allows to run additional operations on top of the elementary ALSA sound controls. A new control access group (three bits in the access flags) was introduced to carry the LED group information for the sound controls. The low-level sound drivers can just mark those controls using this access group. This information is not exported to the user space, but user space can manage the LED sound control associations through sysfs (last patch) per Mark's request. It makes things fully configurable in the kernel and user space (UCM). The actual state ('route') evaluation is really easy (the minimal value check for all channels / controls / cards). If there's more complicated logic for a given hardware, the card driver may eventually export a new read-only sound control for the LED group and do the logic itself. The new LED trigger control code is completely separated and possibly optional (there's no symbol dependency). The full code separation allows eventually to move this LED trigger control to the user space in future. Actually it replaces the already present functionality in the kernel space (HDA drivers) and allows a quick adoption for the recent hardware (ASoC codecs including SoundWire). # lsmod | grep snd_ctl_led snd_ctl_led 24576 0 The sound driver implementation is really easy: 1) call snd_ctl_led_request() when control LED layer should be automatically activated / it calls module_request("snd-ctl-led") on demand / 2) mark all related kcontrols with SNDRV_CTL_ELEM_ACCESS_SPK_LED or SNDRV_CTL_ELEM_ACCESS_MIC_LED v4 changes: - the LED access flags are private to kernel now (no user space API change) - fixes (kctl management, sysfs cleanup) - add the sysfs LED marking kcontrol management - https://lore.kernel.org/alsa-devel/28fffebd-1ce9-7480-0f2f-ed8369abddf1@per… v3 changes: - reorder the controls_rwsem use to fix the remaining mutex issue card->controls_rwsem <-> snd_ctl_layer_rwsem v2 changes: - fix the locking - remove the controls_rwsem read lock in the element get (the consistency is already protected with the global snd_ctl_led_mutex and possible partial value writes are catched with the next value change notification callback) - rename state to brightness and show the brightness unsigned integer value instead the text on/off string (sync with the LED core routines) - remove snd_ctl_led_hello() function (CI warning) - make snd_ctl_led_get_by_access() function static (CI warning) - move snd_ctl_layer_rwsem lock before the registraction callback call in snd_ctl_register_layer() - optimization v1: - https://lore.kernel.org/alsa-devel/20210211111400.1131020-1-perex@perex.cz/ Original RFC: - https://lore.kernel.org/alsa-devel/20210207201157.869972-1-perex@perex.cz/ Cc: Hans de Goede <hdegoede(a)redhat.com> Jaroslav Kysela (6): ALSA: control - introduce snd_ctl_notify_one() helper ALSA: control - add layer registration routines ALSA: control - add generic LED trigger module as the new control layer ALSA: HDA - remove the custom implementation for the audio LED trigger ALSA: control - add sysfs support to the LED trigger module ALSA: led control - add sysfs kcontrol LED marking layer include/sound/control.h | 35 +- sound/core/Kconfig | 6 + sound/core/Makefile | 2 + sound/core/control.c | 182 ++++++-- sound/core/control_led.c | 770 ++++++++++++++++++++++++++++++++ sound/pci/hda/Kconfig | 4 +- sound/pci/hda/hda_codec.c | 69 +-- sound/pci/hda/hda_generic.c | 162 ++----- sound/pci/hda/hda_generic.h | 15 +- sound/pci/hda/hda_local.h | 16 +- sound/pci/hda/patch_ca0132.c | 4 +- sound/pci/hda/patch_realtek.c | 2 +- sound/pci/hda/patch_sigmatel.c | 6 +- sound/pci/hda/thinkpad_helper.c | 2 +- 14 files changed, 1011 insertions(+), 264 deletions(-) create mode 100644 sound/core/control_led.c -- 2.29.2

No active event for loopback
by Jonas Holmberg 30 Mar '21

30 Mar '21

I don't get an active-event when a loopback device becomes active if format, rate and channels has changed. If I use aplay and alasctl monitor it looks like this: aplay -D hw:0,0,0 -f S32_LE -r 48000 -c 1 -s 1 /dev/zero => node hw:0, #0 (3,1,0,PCM Slave Active,0) VALUE node hw:0, #0 (3,1,0,PCM Slave Active,0) VALUE I.e. active value is true when playback starts and false when playback stops. aplay -D hw:0,0,0 -f S16_LE -r 48000 -c 1 -s 1 /dev/zero => node hw:0, #0 (3,1,0,PCM Slave Format,0) VALUE node hw:0, #0 (3,1,0,PCM Slave Active,0) VALUE I.e. format is changed to S16_LE when playback starts and active is false when playback stops. But no active-event was sent when playback started. The same happens if rate and channels changes: aplay -D hw:0,0,0 -f S16_LE -r 32000 -c 1 -s 1 /dev/zero => node hw:0, #0 (3,1,0,PCM Slave Rate,0) VALUE node hw:0, #0 (3,1,0,PCM Slave Active,0) VALUE aplay -D hw:0,0,0 -f S16_LE -r 32000 -c 2 -s 1 /dev/zero => node hw:0, #0 (3,1,0,PCM Slave Channels,0) VALUE node hw:0, #0 (3,1,0,PCM Slave Active,0) VALUE If all params are changed back at the same time only a format event is sent: aplay -D hw:0,0,0 -f S32_LE -r 48000 -c 1 -s 1 /dev/zero => node hw:0, #0 (3,1,0,PCM Slave Format,0) VALUE node hw:0, #0 (3,1,0,PCM Slave Active,0) VALUE Do format, rate and channels events always imply that the device becomes active or is it a bug that no active-event is sent when the device becomes active if a param has changed? /Jonas

[PATCH 0/2] soundwire: configure block packing mode with new
by Bard Liao 30 Mar '21

30 Mar '21

The existing code multiply a channel number by zero (SDW_BLK_GRP_CNT_1), and the result is used to configure the block packing mode. Sampling grouping and channel packing are two separate concepts in SoundWire. In addition, the bandwidth allocation allocates a vertical slice for each stream, which makes the use of the PER_CHANNEL packing mode irrelevant.

[PATCH] soundwire: cadence: only prepare attached devices on clock stop
by Bard Liao 30 Mar '21

30 Mar '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> We sometimes see COMMAND_IGNORED responses during the clock stop sequence. It turns out we already have information if devices are present on a link, so we should only prepare those when they are attached. In addition, even when COMMAND_IGNORED are received, we should still proceed with the clock stop. The device will not be prepared but that's not a problem. The only case where the clock stop will fail is if the Cadence IP reports an error (including a timeout), or if the devices throw a COMMAND_FAILED response.

[PATCH v5 0/9] soundwire: qcom: various improvements
by Srinivas Kandagatla 30 Mar '21

30 Mar '21

Thanks for reviewing v4 of this patchset! During testing SoundWire controller on SM8250 MTP, we found few issues like all the interrupts are not handled, all transport parameters are not read from device tree. Patch to add Auto Enumeration supported by the controller is also part of this series. Other major issue was register read/writes which was interrupt based was an overhead and puts lot of limitation on context it can be used from. With previous approach number of interrupts generated after enumeration are around 130: $ cat /proc/interrupts | grep soundwire 21: 130 0 0 0 0 0 0 0 GICv3 234 Edge soundwire after this patch they are just 3 interrupts $ cat /proc/interrupts | grep soundwire 21: 3 0 0 0 0 0 0 0 GICv3 234 Edge soundwire So this patchset add various improvements to the existing driver to address above issues. Tested it on SM8250 MTP with 2x WSA881x speakers, HeadPhones on WCD938x via lpass-rx-macro and Analog MICs via lpass-tx-macro. Also tested on DragonBoard DB845c with 2xWSA881x speakers.

[PATCH 1/3] ASoC: SOF: parse multiple SSP DAI and hw configs
by Kai Vehmanen 29 Mar '21

29 Mar '21

From: Jaska Uimonen <jaska.uimonen(a)linux.intel.com> ASoC parses multiple hw_configs defined in topology. However currently in SOF only the first config is used and others are discarded. First change SOF driver to parse and save possible multiple configs in ssp case. Also save the default config value provided by ASoC. Functionality with only one defined config stays the same.

Adding movable PCIe BARs support in snd_hda_intel
by Andrey Grodzovsky 29 Mar '21

29 Mar '21

Hi, I am working on adding AMD related drivers support for PCIe BARs move feature developed by Sergei (https://linuxplumbersconf.org/event/7/contributions/847/attachments/584/103…). His feature is still not upstream, all his code and mine on top can be seen here - https://cgit.freedesktop.org/~agrodzov/linux/log/?h=yadro/pcie_hotplug/mova… I did basic implementation fro amdgpu driver and now I am doing the same for snd_hda_intel to support our on GPU Azalia audio chips. This relevant commit is here - https://cgit.freedesktop.org/~agrodzov/linux/commit/?h=yadro/pcie_hotplug/m… Any driver that wants to support movable BARs needs to implement rescan_prepare, rescan_done and bar_fixed callbacks where rescan_prepare needs to stop HW/SW and unamp all MMIO mappings and rescan_done needs to ioremap the BAR from it's new MMIO location and restart HW/SW. I am able currently to trigger BARs move by sysfs using "/sys/bus/pci/rescan" and the driver will go through the sequence I described above without hangs. Problem is that after this when i try to use mplayer I am getting following errors: andrey@andrey-test:~$ sudo mplayer -ao alsa:device=hw=0.3 Downloads/file_example_MP3_5MG.mp3 MPlayer 1.3.0 (Debian), built with gcc-9 (C) 2000-2016 MPlayer Team do_connect: could not connect to socket connect: No such file or directory Failed to open LIRC support.

I enabled MMIO trace and didn't see that post BAR move there is a wrong MMIO access - all of them are from the new MMIO base offset - 0xfcd80000 (trace attached including mmio trace and dmesg) I would be happy for any idea on this and any comment on the correctness of my sequence in the code Andrey

[PATCH 2/2] ASoC: tlv320aic32x4: Register clocks before registering component
by Annaliese McDermond 29 Mar '21

29 Mar '21

Clock registration must be performed before the component is registered. aic32x4_component_probe attempts to get all the clocks right off the bat. If the component is registered before the clocks there is a race condition where the clocks may not be registered by the time aic32x4_componet_probe actually runs.

[PATCH 0/2] ASoC: tlv320aic32x4: Bugfixes for tlv320aic32x4 driver
by Annaliese McDermond 29 Mar '21

29 Mar '21

These are a couple of bugfixes for the tlv320aic32x4 driver that we discovered after the Raspberry Pi Foundation's move to the 5.10 kernel. The first increases the maximum value in the regmap configuration so that the powerup command actually works. The second changes the ordering of the clock registration in the module probe function so that the clocks are properly registered before the component probe function runs.

[PATCH 1/2] ALSA: hda: Re-add dropped snd_poewr_change_state() calls
by Takashi Iwai 29 Mar '21

29 Mar '21

The card power state change via snd_power_change_state() at the system suspend/resume seems dropped mistakenly during the PM code rewrite. The card power state doesn't play much role nowadays but it's still referred in a few places such as the HDMI codec driver. This patch restores them, but in a more appropriate place now in the prepare and complete callbacks.

[PATCH] ASoC: audio-graph-card: Add audio mixer for Motorola mdm6600
by Pavel Machek 29 Mar '21

29 Mar '21

motmdm.c handles audio configuration on "gsmtty2"; it needs to know whether we are in call or not; that part is in motmdm-state.c and listens on "gsmtty1". To configure Alsamixer for voice calls do for example: Speaker Right -> Voice Call Noise Cancellation -> Unmute Call Output -> Speakerphone Call -> 100 Mic2 -> 40 Left -> Mic 2 Voice -> 55 Mic2 -> 40 Left -> Mic 2 Tony wrote original version using custom interface to n_gsm, Pavel switched it to plain serdev and split it to two drivers to be easier to debug and understand.

[PATCH v5 1/2] platform/x86: dell-privacy: Add support for Dell hardware privacy
by Perry Yuan 28 Mar '21

28 Mar '21

From: Perry Yuan <perry_yuan(a)dell.com> add support for Dell privacy driver for the Dell units equipped hardware privacy design, which protect users privacy of audio and camera from hardware level. Once the audio or camera privacy mode activated, any applications will not get any audio or video stream when user pressed ctrl+F4 hotkey, audio privacy mode will be enabled, micmute led will be also changed accordingly The micmute led is fully controlled by hardware & EC(embedded controller) and camera mute hotkey is Ctrl+F9. Currently design only emmits SW_CAMERA_LENS_COVER event while the camera lens shutter will be changed by EC & hw(hadware) control *The flow is like this: 1) User presses key. HW does stuff with this key (timeout timer is started) 2) WMI event is emitted from BIOS to kernel 3) WMI event is received by dell-privacy 4) KEY_MICMUTE emitted from dell-privacy 5) Userland picks up key and modifies kcontrol for SW mute 6) Codec kernel driver catches and calls ledtrig_audio_set, like this: ledtrig_audio_set(LED_AUDIO_MICMUTE, rt715->micmute_led ? LED_ON :LED_OFF); 7) If "LED" is set to on dell-privacy notifies EC, and timeout is cancelled, HW mic mute activated.

[PATCH 1/1] Adding some Roland devices' USB digital audio
by Lucas 28 Mar '21

28 Mar '21

A few days ago, I found this excellent informational post, and that Mike Oliphant's patch is in mainline now: http://blog.nostatic.org/2020/01/getting-boss-gt-1-effects-processor-to.html Since I was fairly certain it applies to the Roland devices I own, I added my USB IDs. Wonderfully, now USB audio capture seems to be working perfectly from the three devices I can test: the INTEGRA-7, Boutique D-05, & VG-99! I've also tested all three for playback capability, since that's implied when a device is using implicit feedback, which I hadn't realized the first time around. Anyway, they all seem to be working as expected for playback too. There are two caveats for playback, though: 1. The INTEGRA-7 won't output playback in any mode other than its "96[kHz]" setting, though capture works with all of its Sample Rate choices. 2. The D-05's analog outputs aren't as clean as the other two devices, with little quiet occasional clicks sounding something like dust on an LP record's play. Possibly that can be chalked up to it having only 1/8" minijack connections, but I suspect something more driver-related as I've not noticed it during use as a synthesizer. Its firmware version is "1.02(1033)," so not up-to-date which may mean it's just the hardware itself, but I've decided not to risk any changes with it yet. If I knew I could revert it, that would be another story. Also USB captures from it, play perfectly cleanly on my usual sound device, the Edirol UA-4FX. You probably already know this, as someone coded them, but here are the commands I've had to use for format compatibility with these devices: D-05: arecord -D hw:Boutique -f S32_LE -c 2 -r 96000 ./file.wav aplay -D hw:Boutique -f S32_LE -c 2 -r 96000 ./file.wav INTEGRA-7: arecord -D hw:INTEGRA7 -f S32_LE -c 2 -r 96000 ./file.wav (then change MENU->SYSTEM->SOUND->Sampling Rate to 44.1 [kHz] (otherwise its 96[kHz]) and change MENU->SYSTEM->SOUND->Ext Part Source Select to USB AUDIO) arecord -D hw:INTEGRA7 -f S32_LE -c 2 -r 44100 ./file-44100.wav aplay -D hw:INTEGRA7 -f S32_LE -c 2 -r 44100 ./file-44100.wav VG-99: arecord -D hw:VG99 -f S24_3LE -c 2 -r 44100 ./file.wav aplay -D hw:VG99 -f S24_3LE -c 2 -r 44100 ./file.wav I searched a bit for other Roland devices people have had USB digital audio issues with over the years, and took the liberty of adding them to the patch too. Likely there are still many more, especially in the Boutique line, but I couldn't find their USB IDs. I have another of the devices I added, with the patch, arriving soon (the R-26) so I'll have to get back to you with how that works too. I hope this can be added to the mainline kernel too, as this support should help many that have struggled. I, certainly, have been hoping somebody would figure this out for quite a while, and even bought a USB through/monitoring device to try to develop it myself (sadly, the software supporting that has its own bugs, so I probably should've just used wireshark). Suffice it to say, I'm quite happy to have this figured out, and to not have to delve into stuff I know nothing about! :) Thanks to anyone looking into adding this, Lucas The patch follows: diff -Nurp linux-5.11.9.orig/sound/usb/implicit.c linux-5.11.9.roland/sound/usb/implicit.c --- linux-5.11.9.orig/sound/usb/implicit.c 2021-03-24 05:54:19.000000000 -0500 +++ linux-5.11.9.roland/sound/usb/implicit.c 2021-03-26 21:43:10.177824402 -0500 @@ -71,27 +71,55 @@ static const struct snd_usb_implicit_fb_ .ep_num = 0x84, .iface = 0 }, /* MOTU MicroBook II */ /* No quirk for playback but with capture quirk (see below) */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00a6), /* Roland JUNO-G */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00ad), /* Roland SH-201 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00b2), /* Roland VG-99 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00c7), /* Roland V-Synth GT */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0111), /* Roland GAIA SH-01 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0120), /* Roland OCTA-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x012b), /* Roland DUO-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x012f), /* Roland QUAD-CAPTURE */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0130), /* BOSS BR-80 */ - IMPLICIT_FB_SKIP_DEV(0x0582, 0x0171), /* BOSS RC-505 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0138), /* BOSS RC-300 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x013e), /* Roland R-26 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x015b), /* Roland INTEGRA-7 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0171), /* BOSS RC-505 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x017c), /* Roland TR-8 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0185), /* BOSS GP-10 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0189), /* BOSS GT-100v2 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x01b5), /* Roland JP-08 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01d6), /* BOSS GT-1 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01d8), /* BOSS Katana */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01e5), /* BOSS GT-001 */ - IMPLICIT_FB_SKIP_DEV(0x0582, 0x0203), /* BOSS AD-10 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x01ff), /* Roland D-05 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0203), /* BOSS AD-10 */ {} /* terminator */ }; /* Implicit feedback quirk table for capture: only FIXED type */ static const struct snd_usb_implicit_fb_match capture_implicit_fb_quirks[] = { + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00a6, 0x0d, 0x01), /* Roland JUNO-G */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00ad, 0x0d, 0x01), /* Roland SH-201 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00b2, 0x0d, 0x01), /* Roland VG-99 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00c7, 0x0d, 0x01), /* Roland V-Synth GT */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x0111, 0x0d, 0x01), /* Roland GAIA SH-01 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x0120, 0x0d, 0x01), /* Roland OCTA-CAPTURE */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x012b, 0x0d, 0x01), /* Roland DUO-CAPTURE */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x012f, 0x0d, 0x01), /* Roland QUAD-CAPTURE */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0130, 0x0d, 0x01), /* BOSS BR-80 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x0138, 0x0d, 0x01), /* BOSS RC-300 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x013e, 0x0d, 0x01), /* Roland R-26 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x015b, 0x0d, 0x01), /* Roland INTEGRA-7 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0171, 0x0d, 0x01), /* BOSS RC-505 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x017c, 0x0d, 0x01), /* Roland TR-8 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0185, 0x0d, 0x01), /* BOSS GP-10 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0189, 0x0d, 0x01), /* BOSS GT-100v2 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x01b5, 0x0d, 0x01), /* Roland JP-08 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x01d6, 0x0d, 0x01), /* BOSS GT-1 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x01d8, 0x0d, 0x01), /* BOSS Katana */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x01e5, 0x0d, 0x01), /* BOSS GT-001 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x01ff, 0x0d, 0x01), /* Roland D-05 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0203, 0x0d, 0x01), /* BOSS AD-10 */ {} /* terminator */

I am ignoring > this (because I don't understand it yet). At first, I describe the way to management a pair of isochronous packet streaming for the target device. Any registers of PCR is not used by 002/003. Instead, quadlet write operation to registers of target device is used for the equivalent operations: * 0x'ffff'e000'0110: sampling transfer frequency * 0x'ffff'e000'0100: registration for a pair of isochronous channels * 0x'ffff'e000'0004: start/stop packet streaming (The LED turns on/off). * 0x'ffff'e000'0000: current status of packet streaming Then the target device starts to transfer isochronous packet to IEEE 1394 bus, and listen to isochronous packet from IEEE 1394 bus, according to registered isochronous channels. You can see current implementation in begin_session() helper function in 'sound/firewire/digi00x/digi00x-stream.c'[1]. Of course, you need to keep isochronous bandwidth and channels in advance of packet streaming. Lock operations are used according to specification of IEEE 1394. You need to communicate to 'isochronous resource manager' node at current bus generation (it can differ each generation): * 0x'ffff'f000'0220: bandwidth * 0x'ffff'f000'0224: channel 31-18 * 0x'ffff'f000'0228: channel 17-0 I guess firewire stack on OS X has API for the above operations. The target device has service for applications to get current sampling rate from external inputs; e.g. S/PDIF: * 0x'ffff'e000'0114: rate of external clock source * 0x'ffff'e000'012c: detection of external clock input The target device can also switch source of sampling clock: * 0x'ffff'e000'0118: source of sampling clock The target device can switch mode of optical interface between ADAT and S/PDIF: * 0x'ffff'e000'011c: optical interface mode Next, I describe the way to process audio data frame in the isochronous packet. One isochronous packet consists of Common Isochronous Packet (CIP) header and payload. For example: CIP | quadlet ------- | ---------- header | 0x00130032 | 0x90020000 payload | ... | ... For the fields in CIP header, please refer to IEC 61883-1/6 which came from specification in vendor association (1394TA). Fortunately, the updated version of ancestor specification is freely available, 'Audio and Music Data Transmission Protocol 2.3' (1394 Trade Association, April 24, 2012, Document 2009013)[2]. The remarkable point of 002/003 case is that SYT field is not used, thus media clock recovery is done just by the number of data blocks in sequence of packet for base cycle time (not cleared yet). CIP payload consists of several number of 'data blocks' according to current sampling transfer frequency (STF). The first quadlet of each data block is for MIDI conformant data channel, which has sequence multiplexing. Some multi bit linear audio data channels follows. In detail, please refer to the above specification. The point is that one data block has one audio data frame. In the case of 002/003, the size of data block is: STF | data channel count -------- | ------------------ 44.1 kHz | 1 + 8 + 8 + 2 (MIDI/Analog/ADAT/SPDIF) 48.0 kHz | 1 + 8 + 8 + 2 (MIDI/Analog/ADAT/SPDIF) 88.2 kHz | 1 + 8 + 2 (MIDI/Analog/SPDIF) 96.0 kHz | 1 + 8 + 2 (MIDI/Analog/SPDIF) Well, we need to adjust the number of data blocks in sequence of packet to keep effective sampling rate (='media clock' in IEEE 1722). For this purpose, IEC 61883-1/6 defines two ways; blocking and non-blocking. In blocking way, an packet has fixed number of data blocks or empty packet. An example at 44.1 STF: isoc | the number of data cycle | blocks per packet ----- | ------------------- 0 | 8 1 | 8 2 | 0 3 | 8 4 | 8 5 | 8 6 | 0 ... | ... In non-blocking way, the number data blocks per packet is variable according to sampling timing each isochronous cycle. An example at 44.1 STF: isoc | the number of data cycle | blocks per packet ----- | ------------------- 0 | 6 1 | 6 2 | 5 3 | 6 4 | 5 5 | 6 6 | 5 ... | ... The above is basics of adjustment for media clock. You can see current implementation of ALSA firewire stack in 'calculate_data_blocks()' helper function in 'sound/firewire/amdtp-stream.c'[3]. In the implementation, the sequence of packet to the target device is adjusted independent of the sequence of packet from the target device. As you issued, the lack of adjustment is the cause of pop-noise in generated sound. We need the way to recover media clock in the sequence of packet from the target device. But as long as I know, the way is different between device types and models. For example, the sequence of packet from Windows driver to 002 is different from the one to 003 in the point. It's the reason that the issue is long standing. Additionally, Digi 002 and 003 uses protocol mutated from the above mechanism in the point of media clock. For example, we can see the actual sequence of packet to the target device at 48.0 kHz STF in Robin Gareus' post[5]. By calculating the number of data blocks according to data block counter field in CIP header: number of | data data blocks | block | counter ----------- | ------- - | 0x32 7 | 0x39 7 | 0x40 5 | 0x45 5 | 0x4a 5 | 0x4f 5 | 0x54 5 | 0x59 5 | 0x5e 5 | 0x63 5 | 0x68 7 | 0x6f 7 | 0x76 7 | 0x7d 7 | 0x84 7 | 0x8b 7 | 0x92 7 | 0x99 7 | 0xa0 5 | 0xa5 5 | 0xaa 5 | 0xaf 5 | 0xb4 5 | 0xb9 5 | 0xbe 5 | 0xc3 5 | 0xc8 7 | 0xcf 7 | 0xd6 7 | 0xdd It's neither blocking nor non-blocking. The sequence is relevant to both of packet buffering and audio data frame buffering, thus the above sequence the size of buffering is not something I know. I use DAP Technology FireSpy 810[5] for packet analyzing (fortunately I found it at bargain price in used market). The libhinoko[6] can make your Linux box as packet analyzer and might be useful. Enough later, I'll send you log of packet sequence for long duration (1 min or so) for 003 console and rack. > I have a Pro Tools license on Mac and PC.

[PATCH] Behringer UFX1604: get rid of pops and clicks while on 96000hz
by Geraldo 27 Mar '21

27 Mar '21

Hello everyone! This one has been bugging me for quite a while. I went deep hard in the guts of ALSA to try to solve it, and it turned out to be a minor thing apparently. The problem is old, and every UFX1604 Linux user can attest that it's impossible to use 96000hz in DUPLEX mode without annoying pops and clicks on the capture stream. The fix is simple: after we alter the CLOCK_SOURCE to match our sample rate, let's tell the CLOCK_SELECTOR we want CLOCK_SOURCE 212 (synced to USB SOF) on pin 1. Solves the problem for me, no more pops and clicks while on 96000hz. If you own an UFX1604 please give this patch a good testing. Let me know if it solves the pops and clicks on the input stream for you while on DUPLEX 96000hz. --- clock.c.git 2021-03-22 04:19:55.543485748 -0300 +++ clock.c 2021-03-25 19:23:38.597197159 -0300 @@ -610,6 +610,13 @@ int snd_usb_set_sample_rate_v2v3(struct if (err < 0) return err; + if (chip->usb_id == USB_ID(0x1397, 0x0001)) { /* Behringer UFX1604 */ + printk(KERN_WARNING "Setting clock selector for UFX1604"); + err = uac_clock_selector_set_val(chip, 211, 1); + if (err < 0) + return err; + } + return get_sample_rate_v2v3(chip, fmt->iface, fmt->altsetting, clock); }

Suffice it to say, I'm quite happy to have this figured out, and to not have to delve into stuff I know nothing about! :) Thanks, Lucas The patch follows: diff -Nur ./linux-5.11.9.orig/sound/usb/implicit.c ./linux-5.11.9.roland/sound/usb/implicit.c --- ./linux-5.11.9.orig/sound/usb/implicit.c 2021-03-24 05:54:19.000000000 -0500 +++ ./linux-5.11.9.roland/sound/usb/implicit.c 2021-03-25 03:05:33.414870404 -0500 @@ -71,13 +71,27 @@ .ep_num = 0x84, .iface = 0 }, /* MOTU MicroBook II */ /* No quirk for playback but with capture quirk (see below) */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00a6), /* Roland JUNO-G */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00ad), /* Roland SH-201 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00b2), /* Roland VG-99 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x00c7), /* Roland V-Synth GT */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0111), /* Roland GAIA SH-01 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0120), /* Roland OCTA-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x012b), /* Roland DUO-CAPTURE */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x012f), /* Roland QUAD-CAPTURE */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0130), /* BOSS BR-80 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x0138), /* BOSS RC-300 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x013e), /* Roland R-26 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x015b), /* Roland INTEGRA-7 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0171), /* BOSS RC-505 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x017c), /* Roland TR-8 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0185), /* BOSS GP-10 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0189), /* BOSS GT-100v2 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x01b5), /* Roland JP-08 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01d6), /* BOSS GT-1 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01d8), /* BOSS Katana */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x01e5), /* BOSS GT-001 */ + IMPLICIT_FB_SKIP_DEV(0x0582, 0x01ff), /* Roland D-05 */ IMPLICIT_FB_SKIP_DEV(0x0582, 0x0203), /* BOSS AD-10 */ {} /* terminator */ @@ -85,13 +99,27 @@ /* Implicit feedback quirk table for capture: only FIXED type */ static const struct snd_usb_implicit_fb_match capture_implicit_fb_quirks[] = { + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00a6, 0x0d, 0x01), /* Roland JUNO-G */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00ad, 0x0d, 0x01), /* Roland SH-201 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00b2, 0x0d, 0x01), /* Roland VG-99 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x00c7, 0x0d, 0x01), /* Roland V-Synth GT */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x0111, 0x0d, 0x01), /* Roland GAIA SH-01 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x0120, 0x0d, 0x01), /* Roland OCTA-CAPTURE */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x012b, 0x0d, 0x01), /* Roland DUO-CAPTURE */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x012f, 0x0d, 0x01), /* Roland QUAD-CAPTURE */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0130, 0x0d, 0x01), /* BOSS BR-80 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x0138, 0x0d, 0x01), /* BOSS RC-300 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x013e, 0x0d, 0x01), /* Roland R-26 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x015b, 0x0d, 0x01), /* Roland INTEGRA-7 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0171, 0x0d, 0x01), /* BOSS RC-505 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x017c, 0x0d, 0x01), /* Roland TR-8 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0185, 0x0d, 0x01), /* BOSS GP-10 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0189, 0x0d, 0x01), /* BOSS GT-100v2 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x01b5, 0x0d, 0x01), /* Roland JP-08 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x01d6, 0x0d, 0x01), /* BOSS GT-1 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x01d8, 0x0d, 0x01), /* BOSS Katana */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x01e5, 0x0d, 0x01), /* BOSS GT-001 */ + IMPLICIT_FB_FIXED_DEV(0x0582, 0x01ff, 0x0d, 0x01), /* Roland D-05 */ IMPLICIT_FB_FIXED_DEV(0x0582, 0x0203, 0x0d, 0x01), /* BOSS AD-10 */ {} /* terminator */

[PATCH] soundwire: intel: move to auxiliary bus
by Bard Liao 26 Mar '21

26 Mar '21

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> Now that the auxiliary_bus exists, there's no reason to use platform devices as children of a PCI device any longer. This patch refactors the code by extending a basic auxiliary device with Intel link-specific structures that need to be passed between controller and link levels. This refactoring is much cleaner with no need for cross-pointers between device and link structures. Note that the auxiliary bus API has separate init and add steps, which requires more attention in the error unwinding paths. The main loop needs to deal with kfree() and auxiliary_device_uninit() for the current iteration before jumping to the common label which releases everything allocated in prior iterations.

[PATCH v4 2/2] ASoC: rt715:add micmute led state control supports
by Perry Yuan 26 Mar '21

26 Mar '21

From: Perry Yuan <perry_yuan(a)dell.com> Some new Dell system is going to support audio internal micphone privacy setting from hardware level with micmute led state changing When micmute hotkey pressed by user, soft mute will need to be enabled firstly in case of pop noise, and codec driver need to react to mic mute event to EC(embedded controller) notifying that SW mute is completed Then EC will do the hardware mute physically within the timeout reached This patch allow codec rt715 and rt715 sdca driver to change the local micmute led state. Dell privacy led trigger driver will ack EC when micmute key pressed through this micphone led control interface like hda_generic provided ACPI method defined in dell-privacy micmute led trigger will be called for notifying the EC that software mute has been completed, then hardware audio circuit solution controlled by EC will switch the audio input source off/on Signed-off-by: Perry Yuan <perry_yuan(a)dell.com> -------- v3 -> v4: * remove unused debug log * remove compile flag of DELL privacy * move the micmute_led to local from rt715_priv * when Jaroslav upstream his gerneric LED trigger driver,I will rebase this patch,please consider merge this at first https://lore.kernel.org/alsa-devel/20210211111400.1131020-1-perex@perex.cz/ v2 -> v3: * simplify the patch to reuse some val value * add more detail to the commit info v1 -> v2: * fix some format issue -------- --- sound/soc/codecs/rt715-sdca.c | 12 ++++++++++++ sound/soc/codecs/rt715.c | 12 ++++++++++++ 2 files changed, 24 insertions(+) diff --git a/sound/soc/codecs/rt715-sdca.c b/sound/soc/codecs/rt715-sdca.c index b43ac8559e45..816348ae11a1 100644 --- a/sound/soc/codecs/rt715-sdca.c +++ b/sound/soc/codecs/rt715-sdca.c @@ -12,6 +12,7 @@ #include <linux/version.h> #include <linux/kernel.h> #include <linux/init.h> +#include <linux/leds.h> #include <linux/pm_runtime.h> #include <linux/pm.h> #include <linux/soundwire/sdw.h> @@ -269,6 +270,7 @@ static int rt715_sdca_put_volsw(struct snd_kcontrol *kcontrol, unsigned int reg = mc->reg; unsigned int max = mc->max; int err; + bool micmute_led; val = ucontrol->value.integer.value[0]; if (invert) @@ -287,6 +289,16 @@ static int rt715_sdca_put_volsw(struct snd_kcontrol *kcontrol, return err; } + /* Micmute LED state changed by muted/unmute switch */ + if (mc->invert) { + if (ucontrol->value.integer.value[0] || ucontrol->value.integer.value[1]) { + micmute_led = LED_OFF; + } else { + micmute_led = LED_ON; + } + ledtrig_audio_set(LED_AUDIO_MICMUTE, micmute_led); + } + return 0; } diff --git a/sound/soc/codecs/rt715.c b/sound/soc/codecs/rt715.c index cdcba70146da..db2c0d2ff9d2 100644 --- a/sound/soc/codecs/rt715.c +++ b/sound/soc/codecs/rt715.c @@ -13,6 +13,7 @@ #include <linux/init.h> #include <linux/delay.h> #include <linux/i2c.h> +#include <linux/leds.h> #include <linux/pm_runtime.h> #include <linux/pm.h> #include <linux/soundwire/sdw.h> @@ -88,6 +89,7 @@ static int rt715_set_amp_gain_put(struct snd_kcontrol *kcontrol, RT715_SET_GAIN_MIX_ADC2_L}; unsigned int addr_h, addr_l, val_h, val_ll, val_lr; unsigned int read_ll, read_rl, i, j, loop_cnt; + bool micmute_led; if (strstr(ucontrol->id.name, "Main Capture Switch") || strstr(ucontrol->id.name, "Main Capture Volume")) @@ -95,6 +97,16 @@ static int rt715_set_amp_gain_put(struct snd_kcontrol *kcontrol, else loop_cnt = 1; + /* Micmute LED state changed by muted/unmute switch */ + if (mc->invert) { + if (ucontrol->value.integer.value[0] || ucontrol->value.integer.value[1]) { + micmute_led = LED_OFF; + } else { + micmute_led = LED_ON; + } + ledtrig_audio_set(LED_AUDIO_MICMUTE, micmute_led); + } + for (j = 0; j < loop_cnt; j++) { /* Can't use update bit function, so read the original value first */ if (loop_cnt == 1) { -- 2.25.1

[PATCH v3 0/7] ASoC: codecs: add wcd938x support
by Srinivas Kandagatla 26 Mar '21

26 Mar '21

This patchset adds support for Qualcomm WCD938X codec. Qualcomm WCD9380/WCD9385 Codec is a standalone Hi-Fi audio codec IC connected over SoundWire. This device has two SoundWire devices, RX and TX respectively supporting 4 x ADCs, ClassH, Ear, Aux PA, 2xHPH, 7 x TX diff inputs, 8 DMICs and MBHC. Even though this device has two SoundWire devices, only tx device has access to main codec Control/Status Registers! This patchset along with other SoundWire patches on the list have been tested on SM8250 MTP device. Am planning to send support for MBHC once this driver gets accepted!

[PATCH 0/1] sound: rawmidi: Add framing mode
by David Henningsson 25 Mar '21

25 Mar '21

Hi, When writing an application that records midi (and e g saves it to disk), ultra-low latency isn't really needed, all we need to know is exactly when the midi message came in. The application can then wake up once a second or so, to write the incoming data, including an accurate timestamp for every event, to disk. As far as I can see, the rawmidi interface does not support such a feature at all. There is a snd_rawmidi_status syscall, but its timestamp field is not even filled by the kernel (!). But even if that was fixed, it would not fix the problem as there could be several midi events in the buffer with different timestamps. You could use the seq interface, it does support timestamps, but I can see at least two potential problems with this: First, the seq code runs in a work queue, not in the actual IRQ. This means that midi event is timestamped too late, especially so if the work is delayed for some reason. Second, seq hard-codes the timestamp type to monotonic - there is no monotonic_raw, so the timestamp would be affected by NTP changes. Also, the timespec uses 32-bit for sec and nsec, but I suspect this is less of a problem (unless people constantly record midi for sixty years or so...). So here's a patch that adds a new "framing" mode that stuffs all MIDI data into 16 byte frames, 8 bytes of timestamp, one byte length, up to seven bytes of data. I'll follow up with an alsa-lib patch if this gets merged.

[PATCH v3] sound: rawmidi: Add framing mode
by David Henningsson 25 Mar '21

25 Mar '21

This commit adds a new framing mode that frames all MIDI data into 16-byte frames with a timestamp. The main benefit is that we can get accurate timestamps even if userspace wakeup and processing is not immediate. Signed-off-by: David Henningsson <coding(a)diwic.se> --- Changes in v3: * Bumped protocol version * More checks for invalid combinations in set_params * Frame: Timestamp is 64 bit for seconds and 3 bytes for data * Sets clock and framing individually. (Clock_type is unsigned char instead of clockid_t to avoid padding issues.) * Supports both monotonic and monotonic_raw timestamps * Moved spin lock to after timestamp retreival. Both to decrease time spent in spin lock, and to get more accurate timestamp in case the spin lock is actually busy. include/sound/rawmidi.h | 2 ++ include/uapi/sound/asound.h | 21 +++++++++++-- sound/core/rawmidi.c | 63 +++++++++++++++++++++++++++++++++++-- 3 files changed, 82 insertions(+), 4 deletions(-) diff --git a/include/sound/rawmidi.h b/include/sound/rawmidi.h index 334842daa904..b0057a193c31 100644 --- a/include/sound/rawmidi.h +++ b/include/sound/rawmidi.h @@ -81,6 +81,8 @@ struct snd_rawmidi_substream { bool opened;

Patch for some Roland devices' USB digital audio
by Lucas 25 Mar '21

25 Mar '21

A couple days ago, I found this excellent informational post, and that Mike Oliphant's patch is in mainline now: http://blog.nostatic.org/2020/01/getting-boss-gt-1-effects-processor-to.html Since I was fairly certain it applies to the Roland devices I own, I added my USB IDs. Wonderfully, now USB audio capture seems to be working perfectly from the three devices I can test: the INTEGRA-7, Boutique D-05, & VG-99! I don't know if the D-05 and VG-99 have digital audio playback/output, as I only tried it with the INTEGRA-7. It does work, but only when the INTEGRA-7's "Sampling Rate" is set to "44.1 kHz" and "Ext Part Source Select" is set to "USB AUDIO". I searched a bit for other Roland devices people have had USB digital audio issues with over the years, and took the liberty of adding them to the patch too. Likely there are still many more, especially in the Boutique line, but I couldn't find their USB IDs. I hope this can be added to the mainline kernel too, as this support should help many that have struggled. I, certainly, have been hoping somebody would figure this out for quite a while, and even bought a USB through/monitoring device to try to develop it myself (sadly, the software supporting that has its own bugs, so I probably should've just used wireshark). Suffice it to say, I'm quite happy to have this figured out, and to not have to delve into stuff I know nothing about! :) Thanks, Lucas

[PATCH v5 0/6] Add audio driver base on rpmsg on i.MX platform
by Shengjiu Wang 25 Mar '21

25 Mar '21

On Asymmetric multiprocessor, there is Cortex-A core and Cortex-M core, Linux is running on A core, RTOS is running on M core. The audio hardware device can be controlled by Cortex-M device, So audio playback/capture can be handled by M core. Rpmsg is the interface for sending and receiving msg to and from M core, that we can create a virtual sound on Cortex-A core side. A core will tell the Cortex-M core sound format/rate/channel, where is the data buffer, what is the period size, when to start, when to stop and when suspend or resume happen, each of this behavior there is defined rpmsg command. Especially we designed the low power audio case, that is to allocate a large buffer and fill the data, then Cortex-A core can go to sleep mode, Cortex-M core continue to play the sound, when the buffer is consumed, Cortex-M core will trigger the Cortex-A core to wakeup to fill data. changes in v5: - remove unneeded property in binding doc and driver - update binding doc according to Rob's comments. - Fix link issue reported by kernel test robot changes in v4: - remove the sound card node, merge the property to cpu dai node according to Rob's comments. - sound card device will be registered by cpu dai driver. - Fix do_div issue reported by kernel test robot changes in v3: - add local refcount for clk enablement in hw_params() - update the document according Rob's comments changes in v2: - update codes and comments according to Mark's comments Shengjiu Wang (6): ASoC: soc-component: Add snd_soc_pcm_component_ack ASoC: fsl_rpmsg: Add CPU DAI driver for audio base on rpmsg ASoC: dt-bindings: fsl_rpmsg: Add binding doc for rpmsg audio device ASoC: imx-audio-rpmsg: Add rpmsg_driver for audio channel ASoC: imx-pcm-rpmsg: Add platform driver for audio base on rpmsg ASoC: imx-rpmsg: Add machine driver for audio base on rpmsg .../devicetree/bindings/sound/fsl,rpmsg.yaml | 108 +++ include/sound/soc-component.h | 3 + sound/soc/fsl/Kconfig | 30 + sound/soc/fsl/Makefile | 6 + sound/soc/fsl/fsl_rpmsg.c | 279 ++++++ sound/soc/fsl/fsl_rpmsg.h | 35 + sound/soc/fsl/imx-audio-rpmsg.c | 140 +++ sound/soc/fsl/imx-pcm-rpmsg.c | 918 ++++++++++++++++++ sound/soc/fsl/imx-pcm-rpmsg.h | 512 ++++++++++ sound/soc/fsl/imx-rpmsg.c | 150 +++ sound/soc/soc-component.c | 14 + sound/soc/soc-pcm.c | 2 + 12 files changed, 2197 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/fsl,rpmsg.yaml create mode 100644 sound/soc/fsl/fsl_rpmsg.c create mode 100644 sound/soc/fsl/fsl_rpmsg.h create mode 100644 sound/soc/fsl/imx-audio-rpmsg.c create mode 100644 sound/soc/fsl/imx-pcm-rpmsg.c create mode 100644 sound/soc/fsl/imx-pcm-rpmsg.h create mode 100644 sound/soc/fsl/imx-rpmsg.c -- 2.27.0

[PATCH 1/3] ASoC:codec:max98373: Changed amp shutdown register as volatile
by Ryan Lee 25 Mar '21

25 Mar '21

0x20FF(amp global enable) register was defined as non-volatile, but it is not. Overheating, overcurrent can cause amp shutdown in hardware. 'regmap_write' compare register readback value before writing to avoid same value writing. 'regmap_read' just read cache not actual hardware value for the non-volatile register. When amp is internally shutdown by some reason, next 'AMP ON' command can be ignored because regmap think amp is already ON.

[PATCH v2] ASoC: wm8960: Remove bitclk relax condition in wm8960_configure_sysclk
by Shengjiu Wang 25 Mar '21

25 Mar '21

The call sequence in wm8960_configure_clocking is ret = wm8960_configure_sysclk(); if (ret >= 0) goto configure_clock; .... ret = wm8960_configure_pll(); configure_clock: ... wm8960_configure_sysclk is called before wm8960_configure_pll, as there is bitclk relax on both functions, so wm8960_configure_sysclk always return success, then wm8960_configure_pll() never be called. With this case: aplay -Dhw:0,0 -d 5 -r 48000 -f S24_LE -c 2 audio48k24b2c.wav the required bitclk is 48000 * 24 * 2 = 2304000, bitclk got from wm8960_configure_sysclk is 3072000, but if go to wm8960_configure_pll. it can get correct bitclk 2304000. So bitclk relax condition should be removed in wm8960_configure_sysclk, then wm8960_configure_pll can be called, and there is also bitclk relax function in wm8960_configure_pll.

alsa-project/alsa-utils issue #84 was opened from giggywithit: Hello I design and build audio equipment and would like to know where or how I would go about getting access to the sound states to control a GPIO for a raspberry Pi. What I would like ideally is to control a GPIO state based upon actual non-zero data playback. My desire is to use the GPIO to control a mute function to silence the interactive periods in DAC activity. I know little to nothing about programming but imagine the function is intelligent enough to discern the difference between an open device and actual music playback. Other methods keep open the device to keep from switching off and on, however, I am looking for a more professional and detailed method to create. Any pointers helpful thank you S Issue URL : https://github.com/alsa-project/alsa-utils/issues/84 Repository URL: https://github.com/alsa-project/alsa-utils

[PATCH AUTOSEL 4.4 05/10] ASoC: sgtl5000: set DAP_AVC_CTRL register to correct default value on probe
by Sasha Levin 25 Mar '21

25 Mar '21

From: Benjamin Rood <benjaminjrood(a)gmail.com> [ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ] According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald(a)curbellmedical.com> for finding this error in the first place.

[PATCH AUTOSEL 4.4 04/10] ASoC: rt5651: Fix dac- and adc- vol-tlv values being off by a factor of 10
by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit eee51df776bd6cac10a76b2779a9fdee3f622b2b ] The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer. Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize. Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver.

[PATCH AUTOSEL 4.14 05/16] ASoC: sgtl5000: set DAP_AVC_CTRL register to correct default value on probe
by Sasha Levin 25 Mar '21

25 Mar '21

From: Benjamin Rood <benjaminjrood(a)gmail.com> [ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ] According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald(a)curbellmedical.com> for finding this error in the first place.

[PATCH AUTOSEL 4.19 05/20] ASoC: sgtl5000: set DAP_AVC_CTRL register to correct default value on probe
by Sasha Levin 25 Mar '21

From: Benjamin Rood <benjaminjrood(a)gmail.com> [ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ] According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald(a)curbellmedical.com> for finding this error in the first place.

[PATCH AUTOSEL 4.19 04/20] ASoC: rt5651: Fix dac- and adc- vol-tlv values being off by a factor of 10
by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit eee51df776bd6cac10a76b2779a9fdee3f622b2b ] The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer.

[PATCH AUTOSEL 4.19 03/20] ASoC: rt5640: Fix dac- and adc- vol-tlv values being off by a factor of 10
by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit cfa26ed1f9f885c2fd8f53ca492989d1e16d0199 ] The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer. Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize. Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver.

From: Benjamin Rood <benjaminjrood(a)gmail.com> [ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ] According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald(a)curbellmedical.com> for finding this error in the first place.

[PATCH AUTOSEL 5.4 07/24] ASoC: rt5651: Fix dac- and adc- vol-tlv values being off by a factor of 10
by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit eee51df776bd6cac10a76b2779a9fdee3f622b2b ] The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer. Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize. Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver.

[PATCH v2] ASoC: core: Don't set platform name when of_node is set
by Daniel Baluta 25 Mar '21

25 Mar '21

From: Daniel Baluta <daniel.baluta(a)nxp.com> A DAI link has 3 components: * CPU * platform * codec(s) A component is specified via: * name * of_node * dai_name In order to avoid confusion when building a sound card we disallow matching by both name and of_node (1). soc_check_tplg_fes allows overriding certain BE links by overriding BE link name. This doesn't work well if BE link was specified via DT, because we end up with a link with both name and of_node specified which is conflicting with (1). In order to fix this we need to: * override of_node if component was specified via DT * override name, otherwise.

[PATCH AUTOSEL 5.10 14/39] ASoC: soc-core: Prevent warning if no DMI table is present
by Sasha Levin 25 Mar '21

25 Mar '21

From: Jon Hunter <jonathanh(a)nvidia.com> [ Upstream commit 7de14d581dbed57c2b3c6afffa2c3fdc6955a3cd ] Many systems do not use ACPI and hence do not provide a DMI table. On non-ACPI systems a warning, such as the following, is printed on boot. WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name! The variable 'dmi_available' is not exported and so currently cannot be used by kernel modules without adding an accessor. However, it is possible to use the function is_acpi_device_node() to determine if the sound card is an ACPI device and hence indicate if we expect a DMI table to be present. Therefore, call is_acpi_device_node() to see if we are using ACPI and only parse the DMI table if we are booting with ACPI.

[PATCH AUTOSEL 5.10 12/39] ASoC: sgtl5000: set DAP_AVC_CTRL register to correct default value on probe
by Sasha Levin 25 Mar '21

25 Mar '21

From: Benjamin Rood <benjaminjrood(a)gmail.com> [ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ] According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald(a)curbellmedical.com> for finding this error in the first place.

by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit eee51df776bd6cac10a76b2779a9fdee3f622b2b ] The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer. Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize. Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver.

From: Bard Liao <yung-chuan.liao(a)linux.intel.com> [ Upstream commit 899b12542b0897f92de9ba30944937c39ebb246d ] We do some IO operations in the snd_soc_component_set_jack callback function and snd_soc_component_set_jack() will be called when soc component is removed.

[PATCH AUTOSEL 5.11 14/44] ASoC: soc-core: Prevent warning if no DMI table is present
by Sasha Levin 25 Mar '21

25 Mar '21

From: Jon Hunter <jonathanh(a)nvidia.com> [ Upstream commit 7de14d581dbed57c2b3c6afffa2c3fdc6955a3cd ] Many systems do not use ACPI and hence do not provide a DMI table. On non-ACPI systems a warning, such as the following, is printed on boot. WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name! The variable 'dmi_available' is not exported and so currently cannot be used by kernel modules without adding an accessor. However, it is possible to use the function is_acpi_device_node() to determine if the sound card is an ACPI device and hence indicate if we expect a DMI table to be present. Therefore, call is_acpi_device_node() to see if we are using ACPI and only parse the DMI table if we are booting with ACPI.

[PATCH AUTOSEL 5.11 13/44] ASoC: es8316: Simplify adc_pga_gain_tlv table
by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit bb18c678754ce1514100fb4c0bf6113b5af36c48 ] Most steps in this table are steps of 3dB (300 centi-dB), so we can simplify the table. This not only reduces the amount of space it takes inside the kernel, this also makes alsa-lib's mixer code actually accept the table, where as before this change alsa-lib saw the "ADC PGA Gain" control as a control without a dB scale.

[PATCH AUTOSEL 5.11 12/44] ASoC: sgtl5000: set DAP_AVC_CTRL register to correct default value on probe
by Sasha Levin 25 Mar '21

25 Mar '21

From: Benjamin Rood <benjaminjrood(a)gmail.com> [ Upstream commit f86f58e3594fb0ab1993d833d3b9a2496f3c928c ] According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald(a)curbellmedical.com> for finding this error in the first place.

[PATCH AUTOSEL 5.11 11/44] ASoC: rt5651: Fix dac- and adc- vol-tlv values being off by a factor of 10
by Sasha Levin 25 Mar '21

25 Mar '21

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit eee51df776bd6cac10a76b2779a9fdee3f622b2b ] The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer. Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize. Note this mirrors commit 3f31f7d9b540 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver.

Is there any other way used in the kernel? Don't add (void). Don't add any code just to help static checkers, only do it if it helps humans. The (void) stuff is ugly. We have a __must_check annotation for functions where it's a bug not to check the return and the usb_driver_claim_interface() is not a __must_check function. Just ignore the static checker when it's wrong. When I'm reviewing static checker warnings, I only look at the new ones. Then after I've looked at them, I mark them as old. I currently have 65k old ignored warnings. regards, dan carpenter

[PATCH v4 resend 00/13] MFD/extcon/ASoC: Rework arizona codec jack-detect support
by Hans de Goede 25 Mar '21

25 Mar '21

Hi All, Here is v4 of my series to rework the arizona codec jack-detect support to use the snd_soc_jack helpers instead of direct extcon reporting. As discussed before here is a resend rebased on 5.12-rc2, making sure that all patches this depends on are in place. Lee, can you pick-up patches 1-6 through the MFD tree and then send a pull-req to Mark so that Mark can merge the Asoc parts throught the ASoC tree ? Patches 2-6 touch drivers/extcon, these all have an Ack from Chanwoo Choi for merging these through the MFD tree. Here is some more generic info on this series from the previous cover-letter: This is done by reworking the extcon driver into an arizona-jackdet library and then modifying the codec drivers to use that directly, replacing the old separate extcon child-devices and extcon-driver. This brings the arizona-codec jack-detect handling inline with how all other ASoC codec driver do this. This was developed and tested on a Lenovo Yoga Tablet 1051L with a WM5102 codec. This was also tested by Charles Keepax, one of the Cirrus Codec folks. Regards, Hans Hans de Goede (13): mfd: arizona: Drop arizona-extcon cells extcon: arizona: Fix some issues when HPDET IRQ fires after the jack has been unplugged extcon: arizona: Fix various races on driver unbind extcon: arizona: Fix flags parameter to the gpiod_get("wlf,micd-pol") call extcon: arizona: Always use pm_runtime_get_sync() when we need the device to be awake ASoC/extcon: arizona: Move arizona jack code to sound/soc/codecs/arizona-jack.c ASoC: arizona-jack: Move jack-detect variables to struct arizona_priv ASoC: arizona-jack: Use arizona->dev for runtime-pm ASoC: arizona-jack: convert into a helper library for codec drivers ASoC: arizona-jack: Use snd_soc_jack to report jack events ASoC: arizona-jack: Cleanup logging ASoC: arizona: Make the wm5102, wm5110, wm8997 and wm8998 drivers use the new jack library ASoC: Intel: bytcr_wm5102: Add jack detect support MAINTAINERS | 3 +- drivers/extcon/Kconfig | 8 - drivers/extcon/Makefile | 1 - drivers/mfd/arizona-core.c | 20 - sound/soc/codecs/Makefile | 2 +- .../soc/codecs/arizona-jack.c | 577 +++++++----------- sound/soc/codecs/arizona.h | 44 ++ sound/soc/codecs/wm5102.c | 12 +- sound/soc/codecs/wm5110.c | 12 +- sound/soc/codecs/wm8997.c | 14 +- sound/soc/codecs/wm8998.c | 9 + sound/soc/intel/boards/bytcr_wm5102.c | 28 +- 12 files changed, 325 insertions(+), 405 deletions(-) rename drivers/extcon/extcon-arizona.c => sound/soc/codecs/arizona-jack.c (76%) -- 2.30.1

[PATCH v2 0/2] ASoC: intel: atom: 2 bug-fixes for the atom SST driver
by Hans de Goede 25 Mar '21

25 Mar '21

Hi All, Here is v2 of my bugfix series for the ASoC Intel Atom SST driver. The patches are unchanged except for adding Pierre-Louis' Acked-By and adding a fixed (subject fixed) version of the Fixes: tag which Pierre-Louis suggested. The first patch fixes a bug which is causing audio to now work with pipewire and both Fedora and Arch Linux are moving towards using pipewire as the default sound-server. As such it would be good if we can get these 2 bugfixes added to a 5.12-rc# release.

[PATCH 1/2] ASoC: intel: atom: Stop advertising non working S24LE support
by Hans de Goede 25 Mar '21

25 Mar '21

The SST firmware's media and deep-buffer inputs are hardcoded to S16LE, the corresponding DAIs don't have a hw_params callback and their prepare callback also does not take the format into account. So far the advertising of non working S24LE support has not caused issues because pulseaudio defaults to S16LE, but changing pulse-audio's config to use S24LE will result in broken sound. Pipewire is replacing pulse now and pipewire prefers S24LE over S16LE when available, causing the problem of the broken S24LE support to come to the surface now.

When there is power domain bind with ipg clock, The call flow: devm_regmap_init_mmio_clk - clk_prepare() - clk_pm_runtime_get() cause the power domain of clock always be enabled after regmap_init(). which impact the power consumption. So use devm_regmap_init_mmio instead of devm_regmap_init_mmio_clk.

[RESEND PATCH v2] ASoC: wm8960: Remove bitclk relax condition in wm8960_configure_sysclk
by Shengjiu Wang 24 Mar '21

24 Mar '21

The call sequence in wm8960_configure_clocking is ret = wm8960_configure_sysclk(); if (ret >= 0) goto configure_clock; .... ret = wm8960_configure_pll(); configure_clock: ... wm8960_configure_sysclk is called before wm8960_configure_pll, as there is bitclk relax on both functions, so wm8960_configure_sysclk always return success, then wm8960_configure_pll() never be called. With this case: aplay -Dhw:0,0 -d 5 -r 48000 -f S24_LE -c 2 audio48k24b2c.wav the required bitclk is 48000 * 24 * 2 = 2304000, bitclk got from wm8960_configure_sysclk is 3072000, but if go to wm8960_configure_pll. it can get correct bitclk 2304000. So bitclk relax condition should be removed in wm8960_configure_sysclk, then wm8960_configure_pll can be called, and there is also bitclk relax function in wm8960_configure_pll.

[PATCH v4 0/9] soundwire: qcom: various improvements
by Srinivas Kandagatla 23 Mar '21

23 Mar '21

Thanks for reviewing v3 of this patchset! During testing SoundWire controller on SM8250 MTP, we found few issues like all the interrupts are not handled, all transport parameters are not read from device tree. Patch to add Auto Enumeration supported by the controller is also part of this series. Other major issue was register read/writes which was interrupt based was an overhead and puts lot of limitation on context it can be used from. With previous approach number of interrupts generated after enumeration are around 130: $ cat /proc/interrupts | grep soundwire 21: 130 0 0 0 0 0 0 0 GICv3 234 Edge soundwire after this patch they are just 3 interrupts $ cat /proc/interrupts | grep soundwire 21: 3 0 0 0 0 0 0 0 GICv3 234 Edge soundwire So this patchset add various improvements to the existing driver to address above issues. Tested it on SM8250 MTP with 2x WSA881x speakers, HeadPhones on WCD938x via lpass-rx-macro and Analog MICs via lpass-tx-macro. Also tested on DragonBoard DB845c with 2xWSA881x speakers.

[PATCH] ASoC: wm8960: Fix wrong bclk and lrclk with pll enabled for some chips
by Shengjiu Wang 23 Mar '21

23 Mar '21

The input MCLK is 12.288MHz, the desired output sysclk is 11.2896MHz and sample rate is 44100Hz, with the configuration pllprescale=2, postscale=sysclkdiv=1, some chip may have wrong bclk and lrclk output with pll enabled in master mode, but with the configuration pllprescale=1, postscale=2, the output clock is correct. >From Datasheet, the PLL performs best when f2 is between 90MHz and 100MHz when the desired sysclk output is 11.2896MHz or 12.288MHz, so sysclkdiv = 2 (f2/8) is the best choice.

[PATCH] ASoC: SOF: Intel: hda: drop display power on/off in D0i3 flows
by Kai Vehmanen 23 Mar '21

23 Mar '21

Controller needs to ensure display power is enabled only for HDA controller reset. Drop the display power-up/down calls from D0i3 entry/exit paths. This was previously not possible as codec drivers could not resume the links, and instead controller kept the reference to display power. The state of display power had be maintained in the D0i3 entry/exit code. With commit 87fc20e4a0cb ("ASoC: SOF: Intel: hda: use hdac_ext fine-grained link management"), this is no longer needed and the code can be cleaned up.

Intro and prep for Topology2.0
by GitHub pull_request - edited 23 Mar '21

23 Mar '21

alsa-project/alsa-lib pull request #129 was edited from ranj063: This pull request includes the preparatory commits paving the way for introducing Topology2.0. Existing alsatplg compiler functionality is unmodified. An example implementation of topology with Topology2.0 can be found here: https://github.com/thesofproject/sof/pull/3936 **Introduction to Topology 2.0** ----- Topology2.0 is a high level keyword extension on top of the existing ALSA conf topology format designed to: 1) Simplify the ALSA conf topology definitions by providing high level "classes" so topology designers need to write less config for common object definitions. 2) Allow simple reuse of objects. Define once and reuse (like M4) with the ability to alter objects configuration attributes from defaults. 3) Allow data type and value verification. This is not done today and frequently crops up in FW bug reports. **Common Topology Classes** ----------------------- Topology today has some common classes that are often reused throughout with slightly altered configurations. i.e. widgets (components), pipelines, dais and controls. Topology2.0 introduces the high level concept of reusable "class" like definition for a AIF_IN/AIF_OUT type object that can be used to create topology objects. **Common Topology Attributes** -------------------------- Topology defines a lot of attributes per object with different types and constraints. Today there is no easy way to validate type or constraints and this can lead to many hard to find problems in FW at runtime. A new keyword "DefineAttribute" has been added to define attribute type, size, min value, max value, enum_values. This then allows alsatplg to validate each topology object attribute. Topology Classes define the list of attributes that they use and whether the attribute is mandatory, can be overridden by parent users or is immutable. This also helps alsatplg emit the appropriate errors for attribute misuse. **Common Topology Arguments** ------------------------- Arguments are used to pass essential data needed for instantiating an object particularly needed for the object name. A new keyword "DefineArgument" has been added to define the arguments. The order in which the arguments are defined determines the name for the widget. For example, in the case of the host widget, the name would be constructed as "host.1.playback" where "1" is the pipeline_id argument value and "playback" is the direction argument value. **Attribute Inheritance:** ---------------------- One of the key features of Topology2.0 is howthe attribute values are propagated from a parent object to a child object. This is accomplished by adding attributes/arguments with the same name for a parent and an object. By doing so, when creating a child object, the value for the common attribute is populated from the parent. If the value is provided in the child object instance, then it overrides the value coming from the parent. **ALSA Conf Parser** ---------------- All the changes being proposed and discussed here must be 100% compliant with the ALSA conf parser. i.e. no syntax changes or changes to semantics for any existing keyword. It's intended that there will be NO changes to the ALSA conf parser and all topology building changes will be in the alsatplg compiler.

An example implementation of topology with Topology2.0 can be found here: https://github.com/thesofproject/sof/pull/3936 **Introduction to Topology 2.0** ----- Topology2.0 is a high level keyword extension on top of the existing ALSA conf topology format designed to: 1) Simplify the ALSA conf topology definitions by providing high level "classes" so topology designers need to write less config for common object definitions. 2) Allow simple reuse of objects. Define once and reuse (like M4) with the ability to alter objects configuration attributes from defaults. 3) Allow data type and value verification. This is not done today and frequently crops up in FW bug reports. **Common Topology Classes** ----------------------- Topology today has some common classes that are often reused throughout with slightly altered configurations. i.e. widgets (components), pipelines, dais and controls. This PR introduces the high level concept of reusable "class" like definition for a AIF_IN/AIF_OUT type object that can be used to create topology objects. **Common Topology Attributes** -------------------------- Topology defines a lot of attributes per object with different types and constraints. Today there is no easy way to validate type or constraints and this can lead to many hard to find problems in FW at runtime. A new keyword "DefineAttribute" has been added to define attribute type, size, min value, max value, enum_values. This then allows alsatplg to validate each topology object attribute. Topology Classes define the list of attributes that they use and whether the attribute is mandatory, can be overridden by parent users or is immutable. This also helps alsatplg emit the appropriate errors for attribute misuse. **Common Topology Arguments** ------------------------- Arguments are used to pass essential data needed for instantiating an object particularly needed for the object name. A new keyword "DefineArgument" has been added to define the arguments. The order in which the arguments are defined determines the name for the widget. For example, in the case of the host widget, the name would be constructed as "host.1.playback" where "1" is the pipeline_id argument value and "playback" is the direction argument value. **Attribute Inheritance:** ---------------------- One of the key features of Topology2.0 is howthe attribute values are propagated from a parent object to a child object. This is accomplished by adding attributes/arguments with the same name for a parent and an object. By doing so, when creating a child object, the value for the common attribute is populated from the parent. If the value is provided in the child object instance, then it overrides the value coming from the parent. **ALSA Conf Parser** ---------------- All the changes being proposed and discussed here must be 100% compliant with the ALSA conf parser. i.e. no syntax changes or changes to semantics for any existing keyword. It's intended that there will be NO changes to the ALSA conf parser and all topology building changes will be in the alsatplg compiler.

[PATCH v4 1/2] platform/x86: dell-privacy: Add support for Dell hardware privacy
by Perry Yuan 23 Mar '21

23 Mar '21

From: Perry Yuan <perry_yuan(a)dell.com> add support for Dell privacy driver for the Dell units equipped hardware privacy design, which protect users privacy of audio and camera from hardware level. Once the audio or camera privacy mode activated, any applications will not get any audio or video stream when user pressed ctrl+F4 hotkey, audio privacy mode will be enabled, micmute led will be also changed accordingly The micmute led is fully controlled by hardware & EC(embedded controller) and camera mute hotkey is Ctrl+F9. Currently design only emmits SW_CAMERA_LENS_COVER event while the camera lens shutter will be changed by EC & hw(hadware) control *The flow is like this: 1) User presses key. HW does stuff with this key (timeout timer is started) 2) WMI event is emitted from BIOS to kernel 3) WMI event is received by dell-privacy 4) KEY_MICMUTE emitted from dell-privacy 5) Userland picks up key and modifies kcontrol for SW mute 6) Codec kernel driver catches and calls ledtrig_audio_set, like this: ledtrig_audio_set(LED_AUDIO_MICMUTE, rt715->micmute_led ? LED_ON :LED_OFF); 7) If "LED" is set to on dell-privacy notifies EC, and timeout is cancelled, HW mic mute activated.

alsa-project/alsa-utils issue #82 was opened from nootc: There is a small typo in the alsaloop man page: https://github.com/alsa-project/alsa-utils/blob/c9e9a79c6cfef3212bdb5f9be4f… "-c" is used for both "channels" and "rate". Thankfully, the source thinks otherwise and "-r" is used for "rate". Issue URL : https://github.com/alsa-project/alsa-utils/issues/82 Repository URL: https://github.com/alsa-project/alsa-utils

[PATCH v2 0/3] soundwire: clear bus clash/parity interrupt before the mask is enabled
by Bard Liao 22 Mar '21

22 Mar '21

The SoundWire specification allows a Slave device to report a bus clash or parity error with the in-band interrupt mechanism. Unfortunately, on some platforms, these errors are randomly reported and don't seem to be valid. This series suggests the addition of a Master level quirk to discard such interrupts. The quirk should in theory have been added at the Slave level, but since the problem was detected with different generations of Slave devices it's hard to point to a specific IP. The problem might also be board-dependent and hence dealing with a Master quirk is simpler. v2: - Reorder the patches sequence. - Add comments about each quirk. - Use u64 quirks.

[PATCH 0/3] ALSA: bebob: enable MIDI message transmission for multiple ports
by Takashi Sakamoto 22 Mar '21

22 Mar '21

Hi, Although below models supported by ALSA bebob driver have multiple MIDI ports, the driver just adds one pair of MIDI ports for ALSA Rawmidi interface: * M-Audio ProjectMix I/O * ESI Quatafire 610 The cause comes from two bugs: * The driver registers the number of MIDI conformant data channels into AM824 data block processing layer, instead of the number of MIDI ports. * For Quatafire, the driver counts plugs with MIDI type, however the number of physical MIDI ports is expressed in the number of channels on the plugs. This patchset enables MIDI message transmission for multiple ports.

[PATCH v3 1/2] ALSA: hda/realtek: fix a determine_headset_type issue for a Dell AIO
by Hui Wang 22 Mar '21

22 Mar '21

We found a recording issue on a Dell AIO, users plug a headset-mic and select headset-mic from UI, but can't record any sound from headset-mic. The root cause is the determine_headset_type() returns a wrong type, e.g. users plug a ctia type headset, but that function returns omtp type. On this machine, the internal mic is not connected to the codec, the "Input Source" is headset mic by default. And when users plug a headset, the determine_headset_type() will be called immediately, the codec on this AIO is alc274, the delay time for this codec in the determine_headset_type() is only 80ms, the delay is too short to correctly determine the headset type, the fail rate is nearly 99% when users plug the headset with the normal speed. Other codecs set several hundred ms delay time, so here I change the delay time to 850ms for alc2x4 series, after this change, the fail rate is zero unless users plug the headset slowly on purpose.

From: Perry Yuan <perry_yuan(a)dell.com> Some new Dell system is going to support audio internal micphone privacy setting from hardware level with micmute led state changing When micmute hotkey pressed by user, soft mute will need to be enabled firstly in case of pop noise, and codec driver need to react to mic mute event to EC(embedded controller) notifying that SW mute is completed Then EC will do the hardware mute physically within the timeout reached This patch allow codec rt715 and rt715 sdca driver to change the local micmute led state. Dell privacy led trigger driver will ack EC when micmute key pressed through this micphone led control interface like hda_generic provided ACPI method defined in dell-privacy micmute led trigger will be called for notifying the EC that software mute has been completed, then hardware audio circuit solution controlled by EC will switch the audio input source off/on Signed-off-by: Perry Yuan <perry_yuan(a)dell.com> -------- v4 -> v5: * rebase to latest 5.12 rc4 upstream kernel v3 -> v4: * remove unused debug log * remove compile flag of DELL privacy * move the micmute_led to local from rt715_priv * when Jaroslav upstream his gerneric LED trigger driver,I will rebase this patch,please consider merge this at first https://lore.kernel.org/alsa-devel/20210211111400.1131020-1-perex@perex.cz/ v2 -> v3: * simplify the patch to reuse some val value * add more detail to the commit info v1 -> v2: * fix some format issue -------- --- sound/soc/codecs/rt715-sdca.c | 11 +++++++++++ sound/soc/codecs/rt715.c | 12 ++++++++++++ 2 files changed, 23 insertions(+) diff --git a/sound/soc/codecs/rt715-sdca.c b/sound/soc/codecs/rt715-sdca.c index 20528afbdc57..70e1181f1dee 100644 --- a/sound/soc/codecs/rt715-sdca.c +++ b/sound/soc/codecs/rt715-sdca.c @@ -11,6 +11,7 @@ #include <linux/moduleparam.h> #include <linux/kernel.h> #include <linux/init.h> +#include <linux/leds.h> #include <linux/pm_runtime.h> #include <linux/pm.h> #include <linux/soundwire/sdw.h> @@ -358,6 +359,7 @@ static int rt715_sdca_put_volsw(struct snd_kcontrol *kcontrol, unsigned int mask = (1 << fls(max)) - 1; unsigned int invert = p->invert; int err; + bool micmute_led; for (i = 0; i < 4; i++) { if (ucontrol->value.integer.value[i] != rt715->kctl_switch_orig[i]) { @@ -393,6 +395,15 @@ static int rt715_sdca_put_volsw(struct snd_kcontrol *kcontrol, if (err < 0) return err; } + /* Micmute LED state changed by muted/unmute switch */ + if (invert) { + if (ucontrol->value.integer.value[0] || ucontrol->value.integer.value[1]) { + micmute_led = LED_OFF; + } else { + micmute_led = LED_ON; + } + ledtrig_audio_set(LED_AUDIO_MICMUTE, micmute_led); + } return k_changed; } diff --git a/sound/soc/codecs/rt715.c b/sound/soc/codecs/rt715.c index 34c3357e943b..13686c5239b3 100644 --- a/sound/soc/codecs/rt715.c +++ b/sound/soc/codecs/rt715.c @@ -13,6 +13,7 @@ #include <linux/init.h> #include <linux/delay.h> #include <linux/i2c.h> +#include <linux/leds.h> #include <linux/pm_runtime.h> #include <linux/pm.h> #include <linux/soundwire/sdw.h> @@ -88,6 +89,7 @@ static int rt715_set_amp_gain_put(struct snd_kcontrol *kcontrol, RT715_SET_GAIN_MIX_ADC2_L}; unsigned int addr_h, addr_l, val_h, val_ll, val_lr; unsigned int read_ll, read_rl, i, j, loop_cnt; + bool micmute_led; if (strstr(ucontrol->id.name, "Main Capture Switch") || strstr(ucontrol->id.name, "Main Capture Volume")) @@ -95,6 +97,16 @@ static int rt715_set_amp_gain_put(struct snd_kcontrol *kcontrol, else loop_cnt = 1; + /* Micmute LED state changed by muted/unmute switch */ + if (mc->invert) { + if (ucontrol->value.integer.value[0] || ucontrol->value.integer.value[1]) { + micmute_led = LED_OFF; + } else { + micmute_led = LED_ON; + } + ledtrig_audio_set(LED_AUDIO_MICMUTE, micmute_led); + } + for (j = 0; j < loop_cnt; j++) { /* Can't use update bit function, so read the original value first */ if (loop_cnt == 1) { -- 2.25.1

[PATCH v5 0/2] hardware-privacy-implementation-for-dell-laptop
by Perry Yuan 22 Mar '21

22 Mar '21

From: Perry Yuan <perry_yuan(a)dell.com> Hi All, This patch set is a new driver for Dell mobile platform that has the hardware privacy feature including micmute,camera mute. For micmute led control, the hotkey is Fn + F4, it is a hardware based mute state, and new privacy will prevent micphone void input from hardware layer, any application cannot get voice data when micmute activated. Camera mute use a new hardware design to control the camrea shutter. When video is muted, no OS application should be functionally able to capture images of the person/environment in front of the system Older history: [1]https://patchwork.kernel.org/project/platform-driver-x86/patch/2020122813… [2]https://patchwork.kernel.org/project/alsa-devel/patch/20201103125859.8759… [3]https://www.spinics.net/lists/alsa-devel/msg120537.html [4]https://github.com/thesofproject/linux/pull/2660 [5]https://github.com/thesofproject/linux/issues/2496 Perry Yuan (2): platform/x86: dell-privacy: Add support for Dell hardware privacy ASoC: rt715:add micmute led state control supports .../testing/sysfs-platform-dell-privacy-wmi | 32 ++ drivers/platform/x86/dell/Kconfig | 16 + drivers/platform/x86/dell/Makefile | 3 + drivers/platform/x86/dell/dell-laptop.c | 23 +- drivers/platform/x86/dell/dell-privacy-acpi.c | 164 +++++++++ drivers/platform/x86/dell/dell-privacy-wmi.c | 340 ++++++++++++++++++ drivers/platform/x86/dell/dell-privacy-wmi.h | 35 ++ drivers/platform/x86/dell/dell-wmi.c | 27 +- sound/soc/codecs/rt715-sdca.c | 11 + sound/soc/codecs/rt715.c | 12 + 10 files changed, 650 insertions(+), 13 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi create mode 100644 drivers/platform/x86/dell/dell-privacy-acpi.c create mode 100644 drivers/platform/x86/dell/dell-privacy-wmi.c create mode 100644 drivers/platform/x86/dell/dell-privacy-wmi.h -- 2.25.1
