[alsa-devel] [PATCH] ALSA: hda - Fix silent speaker output due to mute LED fixup
by Takashi Iwai 03 Apr '14

03 Apr '14

The recent fixups for HP laptops to support the mute LED made the speaker output silent on some machines. It turned out that they use the NID 0x18 for the speaker while it's also used for controlling the LED via VREF bits although the current driver code blindly assumes that such a node is a mic pin (where 0x18 is usually so). This patch fixes the problem by only changing the VREF bits and keeping the other pin ctl bits.

[alsa-devel] [PATCH v3] ASoC: sta350: Add codec driver
by Daniel Mack 02 Apr '14

02 Apr '14

From: Sven Brandau <brandau(a)gmx.de> The TI STA350 is an integrated 2.1-channel power amplifier that is controllable over I2C. This patch adds an ASoC driver for it. At a glance, this chip is very similar to the STA320 for which a driver already exists. In details, however, the register maps contain subtle differences which made a whole new driver easier to write and maintain.

[alsa-devel] [PATCH 0/6] ASoC: davinci-mcasp: Dynamic AFIFO and DMA configuration
by Peter Ujfalusi 02 Apr '14

02 Apr '14

Hi, Apart from the first patch which is a rebased resend of a previous patch this series will change the way McASP driver will configure the AFIFO and thus the DMA burst. The AFIFO and DMA configuration will be in one function so it is going to be easier to see the code and debug if needed. The main change is that instead of static tx/rx numevt (which is provided via DT or pdata) we are going to switch to dynamic configuration. With this setup we do not need to place any constraint on the period or buffer size since the AFIFO numevt and the corresponding DMA burst size will be picked according to period size, active serializers and the preferred numevt level. The only case when the code can fail if the period size in words can not be divided evenly by the active serializers, which is unlikely to happen.

[alsa-devel] [PATCH 00/13] ASoC: Move IO and kcontrols to the component level
by Lars-Peter Clausen 02 Apr '14

02 Apr '14

Hi, This series is the first step towards full componentisation of the ASoC core. It moves both the IO abstraction layers within ASoC as well as the standard set of kcontrols to the component level. This for example means we can get rid of constructs like if (w->codec) snd_soc_read(....) else if(w->platform) snd_soc_platform_read(...) Moving the kcontrols to the component level means we can use the same implementation also for other non-CODEC components. E.g. there seems to be an increasing amount of CPU components that have basic signal processing and things like volume controls etc. whose register layout is similar to those used in CODECs. Currently each CPU component driver re-implements these controls by hand. The first two patches introduce two new helper functions which hide the actual implementation on how the CODEC or platform struct that register a control can be obtained from the control. This means that when the actual implementation is changed only the two helper functions need to be updated and not every single driver. The patches that follow that are just cleanups removing unused IO stuff and move all IO functions to soc-io.c. The next step is to make platforms also components. And then finally first the IO abstraction layers in ASoC are unified at the component level and then on top of that the kcontrol helpers are moved to the component level. The series depends on quite a few topic branches related to changes to the core and cleanups for individual drivers. It is probably best to place it on top of asoc-v3.15-2. The patch that moves the kcontrols to the component level also has a runtime dependency on the not yet applied patches that move the ams-delta and mfld_machine controls to the card level. - Lars Lars-Peter Clausen (13): ASoC: Add snd_soc_kcontrol_codec() helper function ASoC: Add snd_soc_kcontrol_platform() helper function ASoC: Prepare SOC_SINGLE_XR_SX controls for regmap ASoC: Move IO functions to soc-io.c ASoC: Drop ASoC level caching from hw_write/hw_read ASoC: Remove IO register modifier callbacks ASoC: Add helper function to cast component back to CODEC ASoC: Track which components have been registered with snd_soc_register_component() ASoC: Let snd_soc_platform subclass snd_soc_component ASoC: Move IO abstraction to the component level ASoC: Move standard kcontrol helpers to the component level ASoC: Remove snd_soc_update_bits_locked() ASoC: dapm: Rename soc_widget_update_bits_locked() to soc_widget_update_bits() include/sound/soc-dapm.h | 1 + include/sound/soc.h | 114 +++++++-- sound/soc/codecs/88pm860x-codec.c | 8 +- sound/soc/codecs/ab8500-codec.c | 12 +- sound/soc/codecs/adav80x.c | 4 +- sound/soc/codecs/ak4641.c | 4 +- sound/soc/codecs/cs4270.c | 2 +- sound/soc/codecs/cs4271.c | 4 +- sound/soc/codecs/cs42l51.c | 4 +- sound/soc/codecs/da7210.c | 4 +- sound/soc/codecs/da7213.c | 4 +- sound/soc/codecs/da732x.c | 4 +- sound/soc/codecs/da9055.c | 2 +- sound/soc/codecs/lm4857.c | 4 +- sound/soc/codecs/max9768.c | 4 +- sound/soc/codecs/max98088.c | 12 +- sound/soc/codecs/max98090.c | 4 +- sound/soc/codecs/max98095.c | 16 +- sound/soc/codecs/pcm1681.c | 4 +- sound/soc/codecs/rt5631.c | 4 +- sound/soc/codecs/sgtl5000.c | 4 +- sound/soc/codecs/sta32x.c | 4 +- sound/soc/codecs/tas5086.c | 4 +- sound/soc/codecs/tlv320aic23.c | 4 +- sound/soc/codecs/tlv320dac33.c | 4 +- sound/soc/codecs/twl4030.c | 10 +- sound/soc/codecs/twl6040.c | 8 +- sound/soc/codecs/wl1273.c | 12 +- sound/soc/codecs/wm2000.c | 8 +- sound/soc/codecs/wm8350.c | 4 +- sound/soc/codecs/wm8400.c | 2 +- sound/soc/codecs/wm8580.c | 2 +- sound/soc/codecs/wm8731.c | 4 +- sound/soc/codecs/wm8753.c | 4 +- sound/soc/codecs/wm8804.c | 4 +- sound/soc/codecs/wm8903.c | 4 +- sound/soc/codecs/wm8904.c | 14 +- sound/soc/codecs/wm8955.c | 4 +- sound/soc/codecs/wm8958-dsp2.c | 32 +-- sound/soc/codecs/wm8960.c | 4 +- sound/soc/codecs/wm8962.c | 8 +- sound/soc/codecs/wm8983.c | 4 +- sound/soc/codecs/wm8985.c | 4 +- sound/soc/codecs/wm8990.c | 2 +- sound/soc/codecs/wm8991.c | 2 +- sound/soc/codecs/wm8994.c | 10 +- sound/soc/codecs/wm8996.c | 4 +- sound/soc/codecs/wm9081.c | 4 +- sound/soc/codecs/wm_adsp.c | 4 +- sound/soc/codecs/wm_hubs.c | 2 +- sound/soc/intel/sst-haswell-pcm.c | 8 +- sound/soc/soc-cache.c | 2 - sound/soc/soc-core.c | 520 ++++++++++++++++---------------------- sound/soc/soc-dapm.c | 91 +------ sound/soc/soc-io.c | 220 +++++++++++++--- 55 files changed, 644 insertions(+), 592 deletions(-) -- 1.8.0

[alsa-devel] [PATCH v8] MIDI driver for Behringer BCD2000 USB device
by Mario Kicherer 02 Apr '14

02 Apr '14

This patch adds initial support for the Behringer BCD2000 USB DJ controller. At the moment, only the MIDI part of the device is working, i.e. knobs, buttons and LEDs. I also plan to add support for the audio part, but I assume that this will require more effort than the rather simple MIDI interface. Progress can be tracked at https://github.com/anyc/snd-usb-bcd2000. Daniel or Clemens: could I get another ACK on this? Thank you both! Best regards, Mario Changes since v7: - replaced snd_card_create with snd_card_new Changes since v6: - applied more style improvements Changes since v5: - use kernel bitmap functions for devices_used Changes since v4: - devices_used as array to support arbitrary number of SNDRV_CARDS - removed unused array "enable" Changes since v3: - applied style and snd_printk changes as suggested by Daniel Mack Changes since v2: - applied more changes from Daniel Mack and Clemens Ladisch Changes since v1: - fixed the various code style issues, thanks to Daniel Mack and checkpatch.pl.

I am not sure I follow this part. We are clearing the 'not selected' registers before we set the one we want.

[alsa-devel] [PATCH] ASoC: core: Only kmemdup binary control buffer if masking
by Charles Keepax 02 Apr '14

02 Apr '14

When writing a binary control we may apply a mask to the first register, as this requires modifying the data the buffer is duplicated, currently this is done for all binary control writes. As most binary controls don't use the mask facility and thus can freely use the original buffer, avoid the kmemdup for these cases.

It's still a hardware error, but, apparently, it happens only when the Linux driver accesses it in a certain way. Which programs work? Which do not? Regards, Clemens

[alsa-devel] pulseaudio and rcar-h2 sound
by Ben Dooks 01 Apr '14

01 Apr '14

I am currently investigating an issue with the rcar-h2 audio driver and a hang when running pulse-audio. From what I can see the issue seems to be an interaction with the driver and the regmap code. The current issue is that whatever is happening causes CPU0 to stall, thus nothing seems to be able to continue. The following errors are detected by the rcu code: INFO: rcu_sched self-detected stall on CPU 0: (1 GPs behind) idle=415/2/0 softirq=3076/3077 (t=10500 jiffies g=520 c=519 q=51) I have been through the regmap code and the locking looks ok. I also enabled as much of the locking checks as I could and it does not produce any useful output as to why it would be deadlocking. I can run the system fine if I replace the rsnd_read, rsnd_write and rsnd_bset code with versions which do not directly use regmap. Does anyone have any experience with this, or any further ideas on how to continue debugging? -- Ben Dooks http://www.codethink.co.uk/ Senior Engineer Codethink - Providing Genius

And you also replace 0xffffffff. I would later send a patch to reset SAI for a true init instead of these lines but not within this patch as it's focusing on the interrupts enabling.

Don't use magic number. It's pretty clear that the so-called magic number is to clear the settings in the registers for driver init as what this driver did at the first place -- no offense but I don't think you would ask this if you check the git-log of the driver.

[alsa-devel] [PATCH] ALSA: usb-audio - Capture and duplex support for Digidesign Mbox 1 sound card.
by Damien Zammit 01 Apr '14

01 Apr '14

This patch completes the support for Digidesign Mbox 1 sound card by adding capture. The issue with this card was that it has two endpoints on the same interface. This patch creates a dual endpoint quirk. The quirk interface needs a second audioformat struct for this to work which I called ".data2". Signed-off-by: Damien Zammit <damien(a)zamaudio.com>

[alsa-devel] [PATCH] ASoC: fsl_sai: Fix buggy configurations in trigger()
by Nicolin Chen 01 Apr '14

01 Apr '14

The current trigger() has two crucial problems: 1) The DMA request enabling operations (FSL_SAI_CSR_FRDE) for Tx and Rx are now totally exclusive: It would fail to run simultaneous Tx-Rx cases. 2) The TERE disabling operation depends on an incorrect condition -- active reference count that only gets increased in snd_pcm_open() and decreased in snd_pcm_close(): The TERE would never get cleared. So this patch overwrites the trigger function by following these rules: A) We continue to support tx-async-while-rx-sync-to-tx case alone, which's originally limited by this fsl_sai driver, but we make the code easy to modify for the further support of the opposite case. B) We enable both TE and RE for PLAYBACK stream or CAPTURE stream but only enabling the DMA request bit (FSL_SAI_CSR_FRDE) of the current direction due to the requirement of SAI -- For tx-async-while-rx-sync-to-tx case, the receiver is enabled only when both the transmitter and receiver are enabled. C) We only enable one side interrupt for each stream since over/underrun on the opposite stream would be resulted from what we've done in rule B: enabling TERE but remaining FRDE disabled, even though the xrun on the opposite direction will not break the current stream. Tested cases: a) aplay test.wav -d5 b) arecord -r44100 -c2 -fS16_LE test.wav -d5 c) arecord -r44100 -c2 -fS16_LE -d5 | aplay d) (aplay test2.wav &); sleep 1; arecord -r44100 -c2 -fS16_LE test.wav -d1 e) (arecord -r44100 -c2 -fS16_LE test.wav -d5 &); sleep 1; aplay test.wav -d1 Signed-off-by: Nicolin Chen <Guangyu.Chen(a)freescale.com> --- sound/soc/fsl/fsl_sai.c | 43 +++++++++++++++++++++++-------------------- sound/soc/fsl/fsl_sai.h | 11 +++++++++++ 2 files changed, 34 insertions(+), 20 deletions(-) diff --git a/sound/soc/fsl/fsl_sai.c b/sound/soc/fsl/fsl_sai.c index f088545..d64c33f 100644 --- a/sound/soc/fsl/fsl_sai.c +++ b/sound/soc/fsl/fsl_sai.c @@ -365,6 +365,7 @@ static int fsl_sai_trigger(struct snd_pcm_substream *substream, int cmd, struct snd_soc_dai *cpu_dai) { struct fsl_sai *sai = snd_soc_dai_get_drvdata(cpu_dai); + bool tx = substream->stream == SNDRV_PCM_STREAM_PLAYBACK; u32 tcsr, rcsr; /* @@ -379,14 +380,6 @@ static int fsl_sai_trigger(struct snd_pcm_substream *substream, int cmd, regmap_read(sai->regmap, FSL_SAI_TCSR, &tcsr); regmap_read(sai->regmap, FSL_SAI_RCSR, &rcsr); - if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK) { - tcsr |= FSL_SAI_CSR_FRDE; - rcsr &= ~FSL_SAI_CSR_FRDE; - } else { - rcsr |= FSL_SAI_CSR_FRDE; - tcsr &= ~FSL_SAI_CSR_FRDE; - } - /* * It is recommended that the transmitter is the last enabled * and the first disabled. @@ -395,22 +388,32 @@ static int fsl_sai_trigger(struct snd_pcm_substream *substream, int cmd, case SNDRV_PCM_TRIGGER_START: case SNDRV_PCM_TRIGGER_RESUME: case SNDRV_PCM_TRIGGER_PAUSE_RELEASE: - tcsr |= FSL_SAI_CSR_TERE; - rcsr |= FSL_SAI_CSR_TERE; + if (!(tcsr & FSL_SAI_CSR_FRDE || rcsr & FSL_SAI_CSR_FRDE)) { + regmap_update_bits(sai->regmap, FSL_SAI_RCSR, + FSL_SAI_CSR_TERE, FSL_SAI_CSR_TERE); + regmap_update_bits(sai->regmap, FSL_SAI_TCSR, + FSL_SAI_CSR_TERE, FSL_SAI_CSR_TERE); + } - regmap_write(sai->regmap, FSL_SAI_RCSR, rcsr); - regmap_write(sai->regmap, FSL_SAI_TCSR, tcsr); + regmap_update_bits(sai->regmap, FSL_SAI_xCSR(tx), + FSL_SAI_CSR_xIE_MASK, FSL_SAI_FLAGS); + regmap_update_bits(sai->regmap, FSL_SAI_xCSR(tx), + FSL_SAI_CSR_FRDE, FSL_SAI_CSR_FRDE); break; case SNDRV_PCM_TRIGGER_STOP: case SNDRV_PCM_TRIGGER_SUSPEND: case SNDRV_PCM_TRIGGER_PAUSE_PUSH: - if (!(cpu_dai->playback_active || cpu_dai->capture_active)) { - tcsr &= ~FSL_SAI_CSR_TERE; - rcsr &= ~FSL_SAI_CSR_TERE; + regmap_update_bits(sai->regmap, FSL_SAI_xCSR(tx), + FSL_SAI_CSR_FRDE, 0); + regmap_update_bits(sai->regmap, FSL_SAI_xCSR(tx), + FSL_SAI_CSR_xIE_MASK, 0); + + if (!(tcsr & FSL_SAI_CSR_FRDE || rcsr & FSL_SAI_CSR_FRDE)) { + regmap_update_bits(sai->regmap, FSL_SAI_TCSR, + FSL_SAI_CSR_TERE, 0); + regmap_update_bits(sai->regmap, FSL_SAI_RCSR, + FSL_SAI_CSR_TERE, 0); } - - regmap_write(sai->regmap, FSL_SAI_TCSR, tcsr); - regmap_write(sai->regmap, FSL_SAI_RCSR, rcsr); break; default: return -EINVAL; @@ -464,8 +467,8 @@ static int fsl_sai_dai_probe(struct snd_soc_dai *cpu_dai) { struct fsl_sai *sai = dev_get_drvdata(cpu_dai->dev); - regmap_update_bits(sai->regmap, FSL_SAI_TCSR, 0xffffffff, FSL_SAI_FLAGS); - regmap_update_bits(sai->regmap, FSL_SAI_RCSR, 0xffffffff, FSL_SAI_FLAGS); + regmap_update_bits(sai->regmap, FSL_SAI_TCSR, 0xffffffff, 0x0); + regmap_update_bits(sai->regmap, FSL_SAI_RCSR, 0xffffffff, 0x0); regmap_update_bits(sai->regmap, FSL_SAI_TCR1, FSL_SAI_CR1_RFW_MASK, FSL_SAI_MAXBURST_TX * 2); regmap_update_bits(sai->regmap, FSL_SAI_RCR1, FSL_SAI_CR1_RFW_MASK, diff --git a/sound/soc/fsl/fsl_sai.h b/sound/soc/fsl/fsl_sai.h index a264185..be26d46 100644 --- a/sound/soc/fsl/fsl_sai.h +++ b/sound/soc/fsl/fsl_sai.h @@ -35,6 +35,16 @@ #define FSL_SAI_RFR 0xc0 /* SAI Receive FIFO */ #define FSL_SAI_RMR 0xe0 /* SAI Receive Mask */ +#define FSL_SAI_xCSR(tx) (tx ?

[alsa-devel] cloning snd_seq_t (or creating one from client id)
by Tobias Schlemmer 31 Mar '14

31 Mar '14

Hi, Recently, I came upon the following problem with the ALSA sequencer interface: I'm surprised that the upcoming version of RtMidi uses one ALSA client per MIDI port. As an end user I'd expect to see only one ALSA client per program instance (e.g. using aconnect -i - o -l). Asking for the reason of that change I got the answer that it has something to do with broken multithread support. Digging deeper into this problem I found out that sequencer handles (snd_seq_t) are not thread safe. So my question is: Could you provide some way to implement multithreaded ALSA clients? My idea is to provide some function int snd_seq_clone(snd_seq_t * old, snd_seq_t ** new) /* clone a sequencer */ and/or int snd_seq_create_from_client(int clientid, snd_seq_t ** new) /* create a sequencer from a given client id */ and/or int snd_seq_split_port(snd_seq_t * old, snd_seq_t ** new, int port) /* create a sequencer that steels a port from old */ For the semantics I think cloned sequencers should act as if they don't know each other. Each one has its own set of ports. While the generation of port numbers still uses the same counter. I don't expect creating a port to be that time critical that it can't use locks. If it helps to ease the implementation one could use a master sequencer with some slaves. If the master sequencer is deleted the slaves are automatically freed and must not be used anymore. And if a subsequencer tries to access a port of another subsequncer, ALSA could just return with an error. Regards, Tobias P.S.: please, CC to me in answers.

[alsa-devel] [PATCH] ASoC: rsnd: fix src clock prepare/unprepare
by Ben Dooks 31 Mar '14

31 Mar '14

As with the previous commit, before a clock can be used it must be prepared for use. Change from clk_enable() and clk_disable() to the versions of the calls which also prepare and un-prepare the clocks. Will fix warnings from the clock code when this is used.

[alsa-devel] [PATCH] ALSA: hda - Enable beep for ASUS 1015E

The `lspci -nnvv` output contains (wrapped for line length): 00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04) Subsystem: ASUSTeK Computer Inc. Device [1043:115d] Signed-off-by: W. Trevor King <wking(a)tremily.us> --- This patch is against git://git.alsa-project.org/alsa-kernel.git master (currently e38d6d3, ALSA: hda - Add Dell headset detection quirk for three laptop models, 2013-12-13), but I imagine it will apply cleanly to any recent branch. I'm happy to fill in any other information folks want, in case there's uncertainty about whether it's just a one-off quirk for my hardware instance, or if it's a general quirk for all 1043:115d devices.

[alsa-devel] [PATCH] ASoC: rsnd: use fast_io for bus
by Ben Dooks 29 Mar '14

29 Mar '14

The rcar sound driver uses regmap to access registers in various parts of the block and uses regmap to manage mappings. The regmap is created without fast_io set, which means it locks with a mutex rather than a lighter-spinlock. The use of the mutex lock causes issues when the IRQ handler is entered as the code needs to read/write register values and thus with lock debugging enabled the system outputs a number of warnings such as: BUG: sleeping function called from invalid context at rnel/locking/mutex.c:616 The rcar registers are all connected via APB bus and thus not that slow to access. The fix is to set the fast_io in the code so that regmap creates the regmap structures using the faster spinlock functions.

With this logic, put function would be easy however get function becomes tedious due to looping on each bit per register for 3 of them in our case.

We will make reg* and mask* instead of arrays and since we use the same structure, the plan is to share the get and put function code. Thanks. Songhee.

[alsa-devel] [PATCH] ALSA: hda - verify pin:cvt connection on preparing a stream for Intel HDMI codec
by mengdong.lin＠intel.com 28 Mar '14

28 Mar '14

From: Mengdong Lin <mengdong.lin(a)intel.com> The pin:converter connection may get reset after S3 on Intel Broadwell HDMI codec. And this can cause multiple pins share a same convertor and mute control will affect each other. We observed a resumed audio playback become silent after S3. This patch verifies pin:cvt connection on preparing a stream, to assure the pin selects the right convetor and an assigned convertor is not shared by other unused pins. Apply this fix-up on Haswell, Broadwell and Baytrail.

[alsa-devel] tlv320aic32x4 Codec ADC and DAC must shutdown to alter clocks
by Mike Looijmans 28 Mar '14

28 Mar '14

My general question: If "my" codec needs to alter the state of the DAPM tree, how can the codec ask or inform the DAPM components of this? This problem occurs on tlv320aic32x4 codecs, but probably applies to many others as well. Using the tlv320aic32x4 a simple loop like this may "crash" the codec: while true do speaker-test -c 2 -t sine -l 1 -r 48000 > /dev/null speaker-test -c 2 -t sine -l 1 -r 44100 > /dev/null done A "crash" means, in this respect that the chip loses some of its settings, malfunctions and often it results in NACKs on I2C commands. I've been trying to properly fix this, but it just won't fit in the framework. The cause is that the DAPM starts the DAC and/or ADC cores while the clocks aren't running, and stops the clocks before shutting down the cores. There is the overall bug of the driver that starts and stops all the clocks in the aic32x4_set_bias_level in the wrong order - it should start them from source to sink, and stop them in the opposite direction, so the PLL must be the first to start and last to stop. Apparently this isn't really critical as I've never observed failure as a result of this. What I cannot fix is that changing the parameters (like clock frequency) must stop the DAC core. The DAPM framework just sets the BIAS to "ON" only once, and does not shut down until after a time out. Which is good. But if the next stream to play needs a different clock setting, the DAC must be stopped first, the code must wait until the DAC has powered down, and then the clocks can be stopped and altered. When all settings are done, the DAC can be restarted. Starting the DAC is the DAPM's task, it's this line that does the job: SND_SOC_DAPM_DAC("Left DAC", "Left Playback", AIC32X4_DACSETUP, 7, 0), I can detect the change in the hw_params, and on the first stream to play, this is called while still in STANDBY or lower levels. However, when the codec is already in ON bias level, how do I tell DAPM that I had to shut down the DAC in order to change the parameters? Just toggling the related bits will keep the DAC powered down. A routine to store and restore the power state is possible, but very ineffective. Especially since the "I must shutdown" conclusion can also be in the clock setting routine. That would result in multiple down-up cycles. -- Mike Looijmans

[alsa-devel] [PATCH v2 0/4] ASoC: davinci-mcasp: Correct start/stop sequences
by Peter Ujfalusi 28 Mar '14

28 Mar '14

Hi, Changes since v1: - Correction for the stop sequence is added - start code cleanup patch added The startup sequence for TX and RX was not correct, not following the programming sequence from the TRM. This could cause initial channel swap when starting TX. When stopping the stream the AFIFO should be stopped as the last step to avoid unpredictable behavior. The change has been tested on AM335x and AM437x but it should be valid for all devices. Regards, Peter --- Peter Ujfalusi (4): ASoC: davinci-mcasp: Correct TX start sequence ASoC: davinci-mcasp: Correct RX start sequence ASoC: davinci-mcasp: When stopping TX/RX stop the AFIFO as the last step ASoC: davinci-mcasp: Move the AFIFO related code under start_tx/rx functions sound/soc/davinci/davinci-mcasp.c | 95 ++++++++++++++++++--------------------- sound/soc/davinci/davinci-mcasp.h | 6 +++ 2 files changed, 49 insertions(+), 52 deletions(-) -- 1.9.1

[alsa-devel] [PATCH v2] ASoC: sta350: Add codec driver
by Daniel Mack 28 Mar '14

28 Mar '14

From: Sven Brandau <brandau(a)gmx.de> The TI STA350 is an integrated 2.1-channel power amplifier that is controllable over I2C. This patch adds an ASoC driver for it. At a glance, this chip is very similar to the STA320 for which a driver already exists. In details, however, the register maps contain subtle differences which made a whole new driver easier to write and maintain.

[alsa-devel] [PATCH 0/2] ASoC: davinci-mcasp: Correct start sequences for TX/RX
by Peter Ujfalusi 28 Mar '14

28 Mar '14

Hi, The startup sequence for TX and RX was not correct, not following the programming sequence from the TRM. This could cause initial channel swap when starting TX. The change has been tested on AM335x and AM437x but it should be valid for all devices.

[alsa-devel] [PATCH v2] ASoC: fsl_sai: Add isr to deal with error flag
by Nicolin Chen 28 Mar '14

28 Mar '14

It's quite cricial to clear error flags because SAI might hang if getting FIFO underrun during playback (I haven't confirmed the same issue on Rx overflow though). So this patch enables those irq and adds isr() to clear the flags so as to keep playback entirely safe.

[alsa-devel] [PATCH] sound: rcar: use fast_io for bus
by Ben Dooks 27 Mar '14

27 Mar '14

The rcar sound driver uses regmap to access registers in various parts of the block and uses regmap to manage mappings. The regmap is created without fast_io set, which means it locks with a mutex rather than a lighter-spinlock. The use of the mutex lock causes issues when the IRQ handler is entered as the code needs to read/write register values and thus with lock debugging enabled the system outputs a number of warnings such as: BUG: sleeping function called from invalid context at rnel/locking/mutex.c:616 The rcar registers are all connected via APB bus and thus not that slow to access. The fix is to set the fast_io in the code so that regmap creates the regmap structures using the faster spinlock functions.

[alsa-devel] [PATCH] ASoC: sta350: Add codec driver
by Daniel Mack 27 Mar '14

27 Mar '14

From: Sven Brandau <brandau(a)gmx.de> The TI STA350 is an integrated 2.1-channel power amplifier that is controllable over I2C. This patch adds an ASoC driver for it. At a glance, this chip is very similar to the STA320 for which a driver already exists. In details, however, the register maps contain subtle differences which made a whole new driver easier to write and maintain. [daniel(a)zonque.org: cleanups, DT property rework, rebased on asoc-next] Signed-off-by: Sven Brandau <brandau(a)gmx.de> --- I'm sending this patch on behalf of Sven Brandau, who wrote the driver, based on earlier bits for the STA320. In case of any pending issue, I will amend and resubmit.

[alsa-devel] [PATCH] ASoC: Add support for multi register mux
by Arun Shamanna Lakshmi 27 Mar '14

27 Mar '14

If the mux uses 1 bit position per input, and requires to set one single bit at a time, then an N bit register can support up to N inputs. In more recent Tegra chips, we have at least greater than 64 inputs which requires at least 2 .reg fields in struct soc_enum.

[alsa-devel] [PATCH] ASoC: fsl_sai: Add isr to deal with error flag
by Nicolin Chen 27 Mar '14

27 Mar '14

It's quite cricial to clear error flags because SAI might hang if getting FIFO underrun during playback (I haven't confirmed the same issue on Rx overflow though). So this patch enables those irq and adds isr() to clear the flags so as to keep playback entirely safe.

[alsa-devel] [PATCH 1/1] ASoC: Samsung: Fix build on multiplatform
by Sachin Kamat 27 Mar '14

27 Mar '14

PCM and S/PDIF drivers referenced mach headers for a trivial data structure. This caused build errors on multiplatform builds as machine headers are not accessible from driver files. Move the data structure definition to the driver header and remove the dependency. While at it rename the structure to avoid multiple definition errors as the same structure is also used by the platform code.

[alsa-devel] Lenovo G580 mic noise when recording
by Nevyan Neykov 27 Mar '14

27 Mar '14

Hello, my lenovo g580(2189, 20150) laptop is using intel hd audio conexant driver( Intel Corporation 7 Series/C210 ) and experiencing lots of noise when trying to record from either external or internal microphone. If I lower mic volume / boost the voice get barely recorded. I am using this line in my alsa conf: options snd-hda-intel model=auto position_fix=2 also tried with model=asus etc..., when using position_fix=1 recording receives lots of cracking noise. I must mention that both mics are working very well under win7/8. Regards.

[alsa-devel] [PATCH RFC v3 0/2] Move dai-link level properties away from dai subnodes
by Jyri Sarha 27 Mar '14

27 Mar '14

This patch is implemented on top of late patches from Jean-Francois Moine [1]. These patches implement the main part of the simple-card changes discussed in alsa-devel mailing list [2].

From: Christopher Freeman <cfreeman(a)nvidia.com> Export the gpio detect function so machine drivers may call it.

[alsa-devel] Fwd: Re: no reset_resume for driver snd-usb-audio for logitech headset H600
by baumber＠hotmail.com 26 Mar '14

26 Mar '14

FWD: Any news to the snd-usb-audio issue? Thanks, Bernhard Old Message: ------------- I have tested the patch with kernel 3.12.0 with suspend and hibernate, and the problem is gone. No messages "no reset_resume for driver snd-usb-audio?" or other negative effects/messages. After resume, the usb_audio_device (Headset) is the master channel in KDE Mixer, as it should be. => So the problem is solved for me. Can you please add the patch to the latest kernels and LTS-kernels or whitelist the workaround for my device (ID 046d:0a29 Logitech, Inc.

[alsa-devel] twl4030 latency update
by Leonardo Gabrielli 26 Mar '14

26 Mar '14

Dear Peter, I was investigating on TWL4030 high playback latency and stumbled in an old thread started by Edgar http://mailman.alsa-project.org/pipermail/alsa-devel/2011-October/045173.ht… where I read this is related to McBSP2 buffer length Recent kernels seems to have the same behavior (I have a debian beagleboardxM with 3.13.3-armv7-x10) Did you manage to get a fix to this problem? Would it be possible? Regards Leonardo -- Dr. Leonardo Gabrielli, PhD student A3Lab - Dept.

[alsa-devel] [Audio Driver Low power state]
by Gomathi Kumar 26 Mar '14

26 Mar '14

Hi all, I am new to kernel work and am trying to understand the low power state of audio driver. I am using ALC262 codec, hda_intel and 3.10 kernel code. In this codec, d3_stop_clk flag is not set. So in the code flow I was able to understand the following. if (!codec->pm_down_notified && !bus->power_keep_link_on && (state & AC_PWRST_CLK_STOP_OK)) this particular condition in hda_power_work function fails, as power_keep_link_on flag is directly based on d3_stop_clk flag. codec->d3_stop_clk = snd_hda_codec_get_supported_ps(codec, fg, AC_PWRST_CLKSTOP); I modified the if condition to not check the power_keep_link_on flag. After this change the audio is consuming lesser power, but I am not able to see it going to suspend/runtime suspend. *Please clarify what is happening when I modify the if condition and how audio device is consuming low power?* *Also please help me understand, the significance of flags EPSS and D3_STOP_CLK and if they can be set by software code. * Thanks, Gomathi

[alsa-devel] [PATCH v3] ASOC: tegra: move AC97 clock handling to the machine driver
by Lucas Stach 25 Mar '14

25 Mar '14

On Tegra the convention is to have a single machine driver that's controlling the whole audio subsystem. This was introduced after the AC97 driver was merged and ever since AC97 has been broken. Move the clock handling to the machine driver, to be in line with the other Tegra drivers and give the machine driver full control over the single Tegra audio PLL.

[alsa-devel] [RFC PATCH] alsa-lib: Call LADSPA activate after all ports are setup

Hey there, I notices mainly swh-plugins (like butterworth_1902) to crash on seek with mplayer or mpd. This is due to their behaviour on relying on the activate call after the control inputs are set. This is not right by LADSPA API description but I see no point in NOT calling activate as late as possible in alsa-lib. Comments?

[alsa-devel] [PATCH v2 00/12] Cleanup card DAPM and control setup
by Lars-Peter Clausen 25 Mar '14

25 Mar '14

This patch series converts all remaining machine drivers that still register their controls and DAPM elements with the CODEC to registering them with the card. The reason for doing this is to be able to remove the hack in the ASoC core that un-sets the name_prefix of a CODEC before calling the init callback for a DAI link. This comes from a time where it was not possible to register controls or DAPM elements at a card level. And removing this hack makes going forward with the componentisation easier and it also looks like the DAI multi-CODEC patch could benefit from this as well. The series depends on topic/pxa and topic/dapm - Lars Lars-Peter Clausen (12): ASoC: ams-delta: Fix compile error ASoC: ams-delta: Convert to table based DAPM and control setup ASoC: mfld_machine: Convert to table based DAPM and control setup ASoC: omap-abe-twl6040: Register machine level DMIC DAPM routes with the card ASoC: omap: rx51: Convert to table based control and DAPM setup ASoC: omap3pandora: Convert to table based DAPM setup ASoC: davinci-evm: Register machine level DAPM elements with the card ASoC: snappercl15: Convert to table based DAPM setup ASoC: s6105-ipcam: Convert to table based DAPM setup ASoC: pxa: magician: Convert to table based DAPM and control setup ASoC: pxa: tosa: Convert to table based DAPM and control setup ASoC: Remove name_prefix un-set during DAI link init hack sound/soc/cirrus/snappercl15.c | 18 +++-------- sound/soc/davinci/davinci-evm.c | 22 +++++-------- sound/soc/intel/mfld_machine.c | 49 ++++++++++++----------------- sound/soc/omap/ams-delta.c | 66 +++++++++++++-------------------------- sound/soc/omap/omap-abe-twl6040.c | 3 +- sound/soc/omap/omap3pandora.c | 31 ++++++------------ sound/soc/omap/rx51.c | 47 +++++----------------------- sound/soc/pxa/magician.c | 34 +++++++------------- sound/soc/pxa/tosa.c | 35 ++++++++------------- sound/soc/s6000/s6105-ipcam.c | 28 ++++++----------- sound/soc/soc-core.c | 7 +---- 11 files changed, 108 insertions(+), 232 deletions(-) -- 1.8.0

The auto-parser may ignore some pins that could be valid when they don't match with the assumption or if there are way too many pins assigned to the same output type. So far, such a pin has been silently ignored, but it's better to leave a message, which would help for debugging and understanding the problem.

[alsa-devel] [hsw dp audio] Muting S/PDIF turns off DP
by Daniel Martin 24 Mar '14

24 Mar '14

Hi, I've a bug here: when playing audio via the speakers of a monitor attached to a DisplayPort and I mute the corresponding S/PDIF (i.e. with alsamixer) then the monitor switches off into standby, unmuting the S/PDIF turns the monitor back on. When muting the S/PDIF while no audio is playing everything is fine. There's no audio daemon running and my ~/.asoundrc contains only: pcm.!default { type hw card 0 device 3 } I've already filed a fdo bug report (drm/intel) for this as I thought it might be related to it: Bug 75729 - [hsw dp audio] Muting S/PDIF turns off DP https://bugs.freedesktop.org/show_bug.cgi?id=75729 Attached to this bug is a `alsa-info.log` too. As stated in the bug report it's not a showstopper for me, but obviously something seems to go wrong and maybe someone has an idea. Thanks, Daniel Martin

It's actually not going to cause a leak there at all since we have an unconditional run through the rest of the function to a double free with references to the list that gets freed, AFAICT there wasn't a leak to start off with. I think what the function needs to do here is bomb out early on -ENOMEM and otherwise trundle on. Anyway, I'll revert this upstream. Thanks for noticing this.

[alsa-devel] Edirol DA2496 and word clock sync
by Brian McNeil 22 Mar '14

22 Mar '14

Hello all; I'm new to the list, and sitting playing with a pair of Edirol DA2496 cards. These support Word Clock synchronisation, which can be done using S/PDIF, a 75 ohm coax cable on the breakout boxes, or with a internal jumper cable between the PCI cards. Unfortunately neither the driver, or Mudita24, were exposing access to the Word Clock. I've managed to patch support into both; doing so with the 3.12.13-rt21 kernel, and mudita24-1.0.3+svn13 from the Ubuntu repositories. This is, mostly, by treating the cards the same as the Delta1010LT. Forgive me being so rusty with C that I've not provided a patch; going to have to redo this and actually build proper diffs for it. I do have a related query, about Xruns - when using an .asoundrc file to merge the two cards into a single virtual card - is there any way to properly suppress backend Xruns that have no impact on the actual recorded audio?

[alsa-devel] Ambiguous DAPM widget names and DPCM
by Daniel Mack 21 Mar '14

21 Mar '14

Hi Mark, Hi Liam, I spent some hours reverse-engineering the DPCM code, and I plan to prepare a patch to add some documentation once I've assembled a fully working setup. However, I have a general question regarding DAPM widget names. DPCM uses DAPM widgets and routes in order to determine the FE <-> BE connections at runtime. The problem with this is that widget names are very ambiguous, as the automatically created widgets for DAIs are named after their stream_name properties, which contain "Playback" or "Capture" for all components in my case. Hence, the code which walks the connections (snd_soc_dapm_dai_get_connected_widgets()) will most likely match the wrong one (which has empty sound/sink lists), which results in a failure like this: [ 16.606268] fe: ASoC: fe no valid playback route I hacked the names of all components so they are unique, but even then, the problem is that snd_soc_dapm_new_dai_widgets() is called twice for the CPU DAI, once from soc_probe_platform(), and later from soc_probe_link_dais(), and both calls would create DAPM widgets with identical names, resulting in the same problem as described above. I don't know how to handle this, but I believe that nobody was really hit by this issue yet, as DPCM doesn't seem to be used widely, at least not by any machine code in mainline. One idea would be to change the automatically generated names of DAI widgets in order to make them unique, or re-factor the lookup routines. Any opinion on that? Do I miss a general consideration here? With more hacks in place, the setup somehow succeeds, but when the stream is opened, we'll hit a BUG() in sound/core/pcm_memory.c, because the FE device's DMA type is undefined. But that's another topic I'll address later. Thanks, Daniel

[alsa-devel] [PATCH v5] ASoC: add RT286 CODEC driver
by bardliao＠realtek.com 21 Mar '14

21 Mar '14

From: Bard Liao <bardliao(a)realtek.com> This patch adds the ALC286 codec driver. ALC286 is a dual mode codec, which can run as HD-A or I2S mode. It is controlled by HD-A verb commands via I2C protocol. The following is the I/O difference between ALC286 and general I2S codecs. 1. A HD-A verb command contains three parts, NID, VID, and PID. And an I2S command contains only two parts: address and data. 2. Not only the register address is written, but the read command also includes the entire write command. 3. rt286 uses different registers for read and write the same bits. As a result, standard regmap is difficult to be used on ALC286. We don't request a standard I/O by snd_soc_codec_set_cache_io anymore. Now we have ,reg_write and .reg_read functions for ALC286's I/O. And we don't use cache due to item 3 above. Some dummy registers (address <= 0xff) are defined for dapm routing. Thhe dummy registers are cache only. Due to item 2 above, HD-A verb commands are put into the address part of regmap. When we issue HD-A verb write commands, the data part of regmap is zero.

[alsa-devel] [PATCH] ASoC: Add support for multi register mux
by Arun Shamanna Lakshmi 21 Mar '14

21 Mar '14

Currently soc_enum structure supports only 2 registers (reg, reg2) for kcontrol. However, it is possible to have multiple registers per mux. This change allows us to control these multiple registers.

[alsa-devel] [PATCH v2] ASoC: tegra: Use flat regcache.
by Dylan Reid 20 Mar '14

20 Mar '14

When using an rbtree cache, there can be allocations the first time a register is accessed. This can cause an attempt to schedule while atomic in the case that the regmap is using a spinlock. This could be fixed by either initializing all the registers or using a flat cache. The register maps for tegra30_ahub and tegra30_i2s are dense and don't save much from using a tree so convert them to flat. Tegra30 changes tested on Norrin, Tegra20 changes compile.

[alsa-devel] Regression caused by "ASoC: core: Rework SOC_DOUBLE_R_SX_TLV add SOC_SINGLE_SX_TLV"
by Thomas Petazzoni 19 Mar '14

19 Mar '14

Brian, Liam, Mark, I am currently bringing up audio support on the Marvell Armada 370 ARM SoC, for which the development board uses the CS42L51 audio codec. It turns out that the commit 1d99f2436d0d1c7741d6dfd9d27b5376cdbbca40 ("ASoC: core: Rework SOC_DOUBLE_R_SX_TLV add SOC_SINGLE_SX_TLV") causes a problem here, and reverting this commit gets things back to normal. Basically, when this commit is applied, the "PCM", "Analog" and "ADC Mixer" volume controls in alsamixer cannot be changed to any other value than 60 or 61. The volume control doesn't allow to go above 61 and below 60. If I remember correctly, at the codec level, the values configured for PCM in registers 0x10 and 0x11 are either 0x0 or 0x1 depending on whether you select 60 or 61 in alsamixer. Reverting the commit mentioned above makes alsamixer behave normally: the volume can be adjusted between 0 and 100 as expected, the values in register 0x10 and 0x11 are meaningful, and the behavior is as expected: with a volume to 0, I hear nothing in my headphones, with a volume set to 100, the volume is maximum, with a nice progressive volume increase in-between. Therefore, I believe that the commit has a problem. I haven't yet investigated where the problem is, maybe just the values passed to SOC_DOUBLE_R_SX_TLV(), or maybe in the implementation of the volume control functions themselves. I can certainly start investigating, but maybe the author of the commit will immediately realize where the problem could be. Thanks a lot!

The snd_compr_open function would always return 0 even if the compressed ops open function failed, obviously this is incorrect.

[alsa-devel] [PATCH] pcm: route: Don't handle no matching chmap as a serious error

19 Mar '14

When find_matching_chmap() returns an error for the non-matching chmap, the caller, snd_pcm_route_open(), also returns an error although it shouldn't be handled as the fatal error. This results in the probe error with PulseAudio and it gives no real output in the end.

regmap deploys the spinlock for the protection when set up in fast_io mode. This may lead to sleep-in-atomic by memory allocation with GFP_KERNEL in regmap_bulk_write().

[alsa-devel] [PATCH v2] ASoC: simple-card: overwrite cpu_dai->fmt with codec_dai->fmt
by Nicolin Chen 18 Mar '14

18 Mar '14

The current simple-card driver separates the daimft for cpu_dai and codec_dai. So we might get different values for them (0x4003 and 0x1003 for example): asoc-simple-card sound-cs42888.12: cpu : 2024000.esai / 4003 / 132000000 asoc-simple-card sound-cs42888.12: codec : cs42888 / 1003 / 24576000 asoc-simple-card sound-cs42888.12: cs42888 <-> 2024000.esai mapping ok This is not allowed at all as we need to keep the DAIFMT settings identical for both the ends of the link. Thus this patch fixes it by overwriting the cpu_dai->fmt with codec_dai->fmt since we defined the DAIFMT_MASTER basing on CODEC at the first place while the other bits are same.

[alsa-devel] [PATCH v2 0/7] Audio support for Armada 370 DB
by Thomas Petazzoni 18 Mar '14

18 Mar '14

Hello, This series of patches enable audio support on the Marvell Armada 370 Development Board. Since both the I2S controller on the SoC side and the I2C audio codec are already supported by the kernel, the amount of work is fairly limited. Changes since v1: * Drop patches "sound: codec: add Device Tree binding to cs42l51" and " sound: soc: enable Kirkwood driver for mvebu platforms" since they have been applied by Mark Brown. * Set DAI format directly in the snd_soc_dai_link structure instead of separately calling snd_soc_dai_set_fmt(). Suggested by Mark Brown. * Do not call snd_soc_dapm_enable_pin(), as Mark Brown mentionned that DAPM widgets default to enabled. It allowed to entirely remove the dai_init operation. * Use devm_snd_soc_register_card() instead of snd_soc_register_card(), as suggested by Mark Brown. * Wrote a Device Tree binding document for the DT binding introduced by this driver. Requested by Mark Brown. * Use the DT to look up the controller and the codec, as suggested by Mark Brown. * Add S/PDIF support, which has been successfully tested. I've kept it as separate patches (for both the ASoC machine driver, and the Device Tree bits), so that it can be reviewed and applied separately. * Modified the commit title so that they contain "ASoC", as requested by Mark Brown. Patches 1 and 2 are to be reviewed/applied by the ASoC maintainer Mark Brown, while patches 3 to 7 are to be reviewed/applied by the ARM mvebu maintainers. Note that the audio support for Armada 370 also needs a fix to the CS42L51, which is being discussed with the author of the change that apparently introduced the problem (see discussion at http://mailman.alsa-project.org/pipermail/alsa-devel/2014-January/071916.ht…).

[alsa-devel] [RFC] ASoC: samsung: don't build pcm and spdif on exynos
by Arnd Bergmann 18 Mar '14

18 Mar '14

In commit d37bdf736d9b "ASoC: samsung: Use ASoC dmaengine code where possible", Mark Brown changed the EXYNOS ASoC code to no longer use the private dma interfaces that are standing in the way of multiplatform enablement. However, in 313367e7bfa "ASoC: Samsung: Update Kconfig for I2S,SPDIF and PCM audio", two new users of that interface appeared, since it is now possible to enable SND_SOC_SAMSUNG_SMDK_SPDIF and SND_SOC_SMDK_WM8994_PCM on all Samsung SoCs including EXYNOS. This patch does a partial revert of 313367e7bfa by allowing these drivers on all samsung platforms except EXYNOS, so we can proceed with the multiplatform patches. If support for these drivers is actually needed on EXYNOS machines, the drivers should probably first be moved over to use the dmaengine code.

[alsa-devel] [PATCH v2 0/4] ASoC: davinci: edma dmaengine PCM and mcasp preparation

18 Mar '14

Hi, This is a cutdown version of the previous [1] series containing only the ASoC part of the edma dmaengine conversion, but without the actual switch to this new edma-pcm platform for the McASP since the edma arch and dmaengine core changes are needed for it to be usable. Changes since v1: - arch and dmaengine patches has been dropped from the ASoC series - Patches has been reordered so only one patch is going to be needed to switch AM335x/AM447x to use the edma-pcm platform driver - all comments from Lars-Peter Clausen has been addressed for the edma-pcm driver - no changes to Kconfig/Makefile - do not yet build the edma-pcm driver. It will be enabled and integrated when we can do the real switch.

[alsa-devel] [PATCH] regmap: Fix possible sleep-in-atomic in fast io mode
by Takashi Iwai 18 Mar '14

18 Mar '14

regmap deploys the spinlock for the protection when set up in fast_io mode. But some places are still left with possible sleep in the lock, typically allocating memory with GFP_KERNEL. This patch fixes these calls by moving the allocations out of the lock. The krealloc() call in regmap_register_patch() makes it unsafe for concurrent accesses, however. But such a use case must be very rare, thus we take rather simplicity over complexity, and add a note in the function description mentioning this restriction.

[alsa-devel] [PATCH RFC] ALSA: oxygen: Xonar DG(X): fix Stereo Upmixing regression
by Clemens Ladisch 18 Mar '14

18 Mar '14

The code introduced in commit 1f91ecc14dee ("ALSA: oxygen: modify adjust_dg_dac_routing function") accidentally disregarded the old value of the playback routing register, so it broke the "Stereo Upmixing" mixer control. The unmuted parts of the channel routing are the same for all settings of the output destination, so it suffices to revert that part of the patch.

[alsa-devel] [PATCH] ASoC: tegra: Use flat regcache.
by Dylan Reid 18 Mar '14

18 Mar '14

When using an rbtree cache, there can be allocations the first time a register is accessed. This can cause an attempt to schedule while atomic in the case that the regmap is using a spinlock. This could be fixed by either initializing all the registers or using a flat cache. The register maps for tegra30_ahub and tegra30_i2s are dense and don't save much from using a tree so convert them to flat.

[alsa-devel] [PATCH 1/2] ASoC: sirf-audio-codec: Remove snd_soc_codec_set_cache_io() call
by Lars-Peter Clausen 18 Mar '14

18 Mar '14

There was a overlap between the snd_soc_codec_set_cache_io() cleanup and the addition of the sirf-audio-codec resulting in the sirf-audio-codec driver still using the old signature of snd_soc_codec_set_cache_io(), which will cause a compile error. Since the core is able to automatically setup IO for this driver we can just remove both the snd_soc_set_cache_io() call and the control_data assignment.

[alsa-devel] [RFC] [PATCH] firewire-lib: add support for AV/C deferred transaction
by Takashi Sakamoto 15 Mar '14

15 Mar '14

Clemens and Stefan, Can I request your comments about attached patch? This is for adding support of deferred transaction into snd-firewire-lib. I confirm some BeBoB devices use this type of transaction. If you have no negative comments, I'll add this patch for my series. For 'undefined interval' between INTERIM and final response, I want to use 'FCP_TIMEOUT_MS' (=125msec) again. In specifications which I can read, there is no limit for this interval. But I need to promise to finish this function for callers. According to AV/C general specification, targets can send INTERIM response one time. But this patch allows to accept several ITERIM responses for device quirks. I don't have devices which have such quirks, but there may be such devices and I want to make codes simpler. Regards Takashi Sakamoto o-takashi(a)sakamocchi.jp

[alsa-devel] [PATCH] ASoC: max98090: Remove unused control_data field
by Lars-Peter Clausen 14 Mar '14

The driver assigns a value to the control_data field of the driver's state struct, but never reads it again. Which means it is unused and can be removed.

[alsa-devel] [PATCH 00/18] edma/ASoC: dmaengine PCM for AM335x and AM447x
by Peter Ujfalusi 14 Mar '14

14 Mar '14

Hi, With this series AM335x and AM447x will use the dmaengine PCM for audio. The daVinci devices will keep using the davinci-pcm for now since I do not have means to test them but the code is written in a way that they can be switched to use the edma-pcm easily (DA850/OMAP-L138 has been tested and audio was working fine). To be able to use the dmaengine PCM I needed to make changes to the edma code in arch/arm/common/ and in drivers/dma/ : Adding support for DMA pause/resume Possibility to select non default event queue/TC for cyclic (audio) dma channels: all devices using the eDMA via dmaengine was assigned to the default EQ/TC (mmc, i2c, spi, etc, and audio). This is not optimal from system performance point of view since sharing the same EQ/TC can cause latency spikes for cyclic channels (long DMA transfers for MMC for example). While debugging the edma to get things sorted out I noticed that the debug was too verbose and the important information was hidden even when the we did not asked for verbose dmaengine debug. I have included some debug cleanups for the edma dmaengine driver also. On the ASoC side: the series has been tested on AM335x and AM447x. I have report that DA850/OMAP-L138 works with this series (which boots w/o DT).

[alsa-devel] please ignore my earlier message regarding R16 quirks
by James Miller 14 Mar '14

14 Mar '14

I'm sorry for my ignorance, but I realised that the device has been reporting itself as 1.1 due to the usb hub being 1.1. This is my first week of looking at usb, and its been a steep learning curve, I am finding my way around the code though, and hope to have something working at some point in the near future. I notice that some cards have boot up quirk functions and I am wondering if that is the problem as the R16 can be switched between its audio interface and a card reader. If I have any more questions, is this the correct list to ask them? Many thanks, James

[alsa-devel] [RFC] ASoC: core: Add support for DAI multicodec
by Benoit Cousson 13 Mar '14

13 Mar '14

From: Misael Lopez Cruz <misael.lopez(a)ti.com> DAI link assumes a one to one mapping between CPU DAI and CODEC. In some cases, the same CPU DAI can be connected to several codecs. This is the case for example, if you connect two mono codecs to the same I2S link in order to have a stereo card. The current ASoC implementation does not allow such setup. Add support for DAI links composed of a single CPU DAI and multiple CODECs. Sound cards have to pass the CODECs array in the corresponding DAI link through a new 'snd_soc_dai_link_codec' struct. Each CODEC in this array is described in the same manner single CODEC DAIs are (either DT/OF node or codec_name). CPU DAI in a multicodec DAI link can have more channels than what each CODEC has. The number of channels each CODEC is responsible for is machine specific, hence it's fixed up in machine drivers in a similar way to what DPCM does. Add few helpers to make the code more readable and fix a trailing space in the header as well. Signed-off-by: Misael Lopez Cruz <misael.lopez(a)ti.com> [bcousson(a)baylibre.com: Adapt the original series to 3.14] Signed-off-by: Benoit Cousson <bcousson(a)baylibre.com> --- Hi Mark and Liam, I'm not sure this is the only way to address that problem, but both Misa and myself were facing the same issue on different platforms, and we didn't find any straighforward way to do that. To avoid breaking all the exiting ASoC implementation, this approach is adding extra attributes for multiple codecs and does not enforce moving every single codec pointer to a multicodec array. The patch is based on 3.14-rc6. Comments are welcome.

[alsa-devel] [PATCH v6] ASoC: tlv320aic31xx: Add basic codec driver implementation
by Jyri Sarha 13 Mar '14

13 Mar '14

This commit adds a bare bones driver support for TLV320AIC31XX family audio codecs. The driver adds basic stereo playback trough headphone and speaker outputs and mono capture trough microphone inputs. The driver is currently missing support at least for mini DSP features and jack detection. I have tested the driver only on TLV320AIC3111, but based on the data sheets TLV320AIC3100, TLV320AIC3110, and TLV320AIC3120 should work Ok too. The base for the implementation was taken from: git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx -branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13.

13 Mar '14

The following changes since commit deeed33850c8a376addabbf971df433b2a1ba74c: Merge remote-tracking branches 'asoc/topic/wm8996', 'asoc/topic/wm9081' and 'asoc/topic/wm9705' into asoc-next (2014-03-12 23:05:31 +0000) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git tags/asoc-v3.15-2 for you to fetch changes up to 56fe48976db38ed3984e0e68b71e503e8179dd89: Merge remote-tracking branch 'asoc/topic/tlv320aic31xx' into asoc-next (2014-03-13 14:19:54 +0000) ---------------------------------------------------------------- ASoC: Updates for v3.15 This is mostly a few additional fixes from Lars-Peter, a new driver and cleaning up a git failure with merging the Intel branch (combined with an xargs failure to pay attention to error codes). The history lists a bunch of additional commits for the branch but the content of those commits is actually present already but not recorded in history due to git failing. Unfortunately xargs is used in the merge script and it doesn't do a good job of noticing errors from the commands it invokes. ---------------------------------------------------------------- Dan Carpenter (4): ASoC: Intel: sst-firmware: missing curly braces (harmless) ASoC: intel: restore IRQs on error ASoC: intel: incorrect sizeof() ASoC: Baytrail: fix error handling in sst_byt_dsp_init() Jarkko Nikula (15): ASoC: Intel: Add common SST driver loader on ACPI systems ASoC: Intel: Move extended fw base and size fields in struct sst_pdata ASoC: Intel: sst-acpi: Request firmware before SST platform driver probing ASoC: Intel: sst-acpi: Add support for multiple machine drivers per platform ASoC: Intel: Add Baytrail SST ID and Baytrail specific register bits ASoC: Intel: Add Intel Baytrail SST DSP support ASoC: Intel: Add Intel Baytrail SST DSP IPC support ASoC: Intel: Add Intel Baytrail SST PCM platform driver ASoC: Intel: Add machine driver for Baytrail SST with RT5640 codec ASoC: Intel: Add Baytrail SST and byt-rt5640 machine driver probing ASoC: Intel: Add build support for Baytrail SST ASoC: Intel: sst-acpi: Fix Oops in case of missing firmware ASoC: Intel: byt-rt5640: Update internal mic and speaker kcontrol names ASoC: Intel: byt-rt5640: Use init time DAI format ASoC: Intel: Baytrail: Fix implicit declaration of function 'memcpy_fromio' Jyri Sarha (1): ASoC: tlv320aic31xx: Add basic codec driver implementation Lars-Peter Clausen (5): ASoC: ams-delta: Fix compile error ASoC: snappercl15: Convert to table based DAPM setup ASoC: pxa: magician: Convert to table based DAPM and control setup ASoC: pxa: tosa: Convert to table based DAPM and control setup ASoC: s6105-ipcam: Convert to table based DAPM setup Liam Girdwood (18): ASoC: Intel: Add a mfld prefix to Intel SST drivers.

[alsa-devel] [PATCH v5] ASoC: tlv320aic31xx: Add basic codec driver implementation
by Jyri Sarha 13 Mar '14

13 Mar '14

This commit adds a bare bones driver support for TLV320AIC31XX family audio codecs. The driver adds basic stereo playback trough headphone and speaker outputs and mono capture trough microphone inputs. The driver is currently missing support at least for mini DSP features and jack detection. I have tested the driver only on TLV320AIC3111, but based on the data sheets TLV320AIC3100, TLV320AIC3110, and TLV320AIC3120 should work Ok too. The base for the implementation was taken from: git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx -branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13. Signed-off-by: Jyri Sarha <jsarha(a)ti.com> --- Since v4 version: - Remove MICBIAS_OFF DT parameter - Remove logging and add missing default: to aic31xx_dapm_power_event() - Take control, widget, and route adding errors into account - Don't try soft reset in power event handler - Remove route to MICBIAS from codec driver damp routing table and add it as output pin to DT doc - Update year in copyright message and change triple newlines to double - Remove internal DAC/ADC routes that were still haunting in the previous patch - Allow PLL reprogramming on the fly as it appears to work just fine BR, Jyri .../devicetree/bindings/sound/tlv320aic31xx.txt | 61 + include/dt-bindings/sound/tlv320aic31xx-micbias.h | 8 + sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tlv320aic31xx.c | 1295 ++++++++++++++++++++ sound/soc/codecs/tlv320aic31xx.h | 258 ++++ 6 files changed, 1628 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/tlv320aic31xx.txt create mode 100644 include/dt-bindings/sound/tlv320aic31xx-micbias.h create mode 100644 sound/soc/codecs/tlv320aic31xx.c create mode 100644 sound/soc/codecs/tlv320aic31xx.h diff --git a/Documentation/devicetree/bindings/sound/tlv320aic31xx.txt b/Documentation/devicetree/bindings/sound/tlv320aic31xx.txt new file mode 100644 index 0000000..74c66de --- /dev/null +++ b/Documentation/devicetree/bindings/sound/tlv320aic31xx.txt @@ -0,0 +1,61 @@ +Texas Instruments - tlv320aic31xx Codec module + +The tlv320aic31xx serial control bus communicates through I2C protocols + +Required properties: + +- compatible - "string" - One of: + "ti,tlv320aic310x" - Generic TLV320AIC31xx with mono speaker amp + "ti,tlv320aic311x" - Generic TLV320AIC31xx with stereo speaker amp + "ti,tlv320aic3100" - TLV320AIC3100 (mono speaker amp, no MiniDSP) + "ti,tlv320aic3110" - TLV320AIC3110 (stereo speaker amp, no MiniDSP) + "ti,tlv320aic3120" - TLV320AIC3120 (mono speaker amp, MiniDSP) + "ti,tlv320aic3111" - TLV320AIC3111 (stereo speaker amp, MiniDSP) + +- reg - <int> - I2C slave address + + +Optional properties: + +- gpio-reset - gpio pin number used for codec reset +- ai31xx-micbias-vg - MicBias Voltage setting + 1 or MICBIAS_2_0V - MICBIAS output is powered to 2.0V + 2 or MICBIAS_2_5V - MICBIAS output is powered to 2.5V + 3 or MICBIAS_AVDD - MICBIAS output is connected to AVDD + If this node is not mentioned or if the value is unknown, then + micbias is set to 2.0V. +- HPVDD-supply, SPRVDD-supply, SPLVDD-supply, AVDD-supply, IOVDD-supply, + DVDD-supply : power supplies for the device as covered in + Documentation/devicetree/bindings/regulator/regulator.txt + +CODEC output pins: + * HPL + * HPR + * SPL, devices with stereo speaker amp + * SPR, devices with stereo speaker amp + * SPK, devices with mono speaker amp + * MICBIAS + +CODEC input pins: + * MIC1LP + * MIC1RP + * MIC1LM + +The pins can be used in referring sound node's audio-routing property. + +Example: +#include <dt-bindings/sound/tlv320aic31xx-micbias.h> + +tlv320aic31xx: tlv320aic31xx@18 { + compatible = "ti,tlv320aic311x";

[alsa-devel] zoom r16 quirks
by James Miller 13 Mar '14

13 Mar '14

Hi, I am trying to get the zoom R16 working with alsa for full duplex operation. I have been able to get the 8 channels of capture working after following jmancine's advice and using the following quirk on ifnum 4: { .ifnum = 4, .type = QUIRK_AUDIO_FIXED_ENDPOINT, .data = & (const struct audioformat) { .formats = SNDRV_PCM_FMTBIT_S24_LE, .channels = 8, .iface = 1, .altsetting = 1, .altset_idx = 1, .attributes = UAC_EP_CS_ATTR_SAMPLE_RATE, .rates = SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000, .rate_min = 44100, .rate_max = 96000, .nr_rates = 4, .rate_table = (unsigned int[]) { 44100, 48000, 88200, 96000 } } }, However, what I discovered was that the ifnum 4 in this case is related to the udev matching rules for the device number, so when I plugged in the zoom, it was being assigned to device 4, which was then matched to the ifnum 4. If I unplugged and replugged the device, it was then designated as device 5 in the udev tree, and wasn't working. I read in quirks-table.h the following: (To work with * hotplugging, bDeviceClass must be set to USB_CLASS_PER_INTERFACE.) so I changed the matching rule macro to : USB_DEVICE_INTERFACE_CLASS(0x1686, 0x00dd, USB_CLASS_AUDIO) to attempt to match the device during udev assignment (in case the device class wasn't returned from the device properly) and then set .binterfaceclass = USB_CLASS_PER_INTERFACE below that before the quirk data. I think that I am heading in the correct direction, although I was wondering if you could confirm the following: Am I correct in assuming that the .ifnum in the quirk is related to udev device matching rules? When I write zoom-quirks.h in the way that I am currently (see below), I get a incorrect maxpacket assignment for interface 3 (midi) and I traced this to: dev_warn(ddev, "config %d interface %d altsetting %d " "bulk endpoint 0x%X has invalid maxpacket %d\n", in config.c line 259. The above bit of code is selected in conditions where the device is usb high speed but I have kern.log reporting that the device is class 1.1. Its a 24 bit chip, and jmancine reports that the device is being incorrectly assigned a 32bit le format for playback when it should be 24bit le, so perhaps this is because of a protocol mismatch? When I have the device successfully recognised the next time, I will check in format.c that it is being assigned the correct bit format, but I am uncertain as to how to confirm what bprotocol to use. Any ideas? Here is the zoom-quirks.h that I am currently using. { /* ZOOM R16 in USB 2.0 mode */ USB_DEVICE_INTERFACE_CLASS(0x1686, 0x00dd, USB_CLASS_AUDIO), .bDeviceClass = USB_CLASS_PER_INTERFACE, .driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) { .ifnum = QUIRK_ANY_INTERFACE, .type = QUIRK_COMPOSITE, .data = (const struct snd_usb_audio_quirk[]) { { .ifnum = 1, /*PLAYBACK*/ .type = QUIRK_AUDIO_FIXED_ENDPOINT, .data = & (const struct audioformat) { .formats = SNDRV_PCM_FMTBIT_S24_LE, .channels = 2, .iface = 1, .altsetting = 1, .altset_idx = 1, .attributes = UAC_EP_CS_ATTR_SAMPLE_RATE, .rates = SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000, .endpoint = 0x03, .ep_attr = (USB_ENDPOINT_XFER_ISOC && USB_ENDPOINT_SYNC_ADAPTIVE && SND_USB_ENDPOINT_TYPE_DATA), .rate_min = 44100, .rate_max = 96000, .nr_rates = 4, .rate_table = (unsigned int[]) { 44100, 48000, 88200, 96000 } } }, { .ifnum = 2, /*CAPTURE*/ .type = QUIRK_AUDIO_FIXED_ENDPOINT, .data = & (const struct audioformat) { .formats = SNDRV_PCM_FMTBIT_S24_LE, .channels = 8, .iface = 2, .altsetting = 1, .altset_idx = 1, .attributes = UAC_EP_CS_ATTR_SAMPLE_RATE, .rates = SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000, .endpoint = 0x84, .ep_attr = (USB_ENDPOINT_XFER_ISOC && USB_ENDPOINT_SYNC_SYNC && USB_ENDPOINT_USAGE_DATA), .rate_min = 44100, .rate_max = 96000, .nr_rates = 4, .rate_table = (unsigned int[]) { 44100, 48000, 88200, 96000 } } }, { .ifnum = 3, .type = QUIRK_MIDI_FIXED_ENDPOINT, }, { .ifnum = -1, }, } } }, Thanks for any help!! -- James Stewart Miller Bsc(hons) Psych.

[alsa-devel] [PATCH] ASoC: Intel: don't select RT5640 if !I2C

From: Stephen Warren <swarren(a)nvidia.com> The rt5640 driver won't compile without I2C enabled.

[alsa-devel] snd_pcm_drain causes repeated playback of last buffer contents
by Sanjeev Chugh 12 Mar '14

12 Mar '14

Hello, I'm not an alsa expert at all but trying to learn alsa. I'm experiencing an issue where on snd_pcm_drain() the slave PCM driven via plugin DSHARE is not filled with silence. Result is endless playback of buffer content until pcm is closed. I'm trying to analyze what could be the reason for this. In my understanding in Alsa, audio data is played as a unit of period. Once playing one period is finished, then next period will be played. If period has lesser frames than the period size, audio data previously played will be re-played until pcm is closed out. Could it be a reason for this continuous playback when snd_pcm_drain is called ? I'm not even sure if it is desired behavior that silence be padded after driver drains the pcm :( I guess it is too big as a bug to be ignored. Thanks Pthread

[alsa-devel] [PATCH] ASoC: Fix use after free
by Lars-Peter Clausen 12 Mar '14

12 Mar '14

Freeing the current list element while iterating over the list will cause a use after free since the iterator function will still use the current element to look up the next.

[alsa-devel] HDA jack retask for Debian 7.4 NOT working
by Subodh Chiwate 12 Mar '14

12 Mar '14

Hi, I am trying to get surround 7.1 on debian 7.4 Wheezy. As guided by hda-jack-retask readme I built it from source on my system. But the changes are not reflecting and no errors by utility as well. I am getting Alsa 1.0.25 from the repository. Do I need to build the latest version from source to get hdajackretask as part of alsa-tools ? Any other suggestions to get the 7.1 working are welcome. Thanks in advance. -- Regards Subodh

[alsa-devel] [PATCH] ASoC: simple-card: overwrite DAIFMT_MASTER of cpu_dai->fmt
by Nicolin Chen 12 Mar '14

12 Mar '14

The current simple-card driver separates the daimft for cpu_dai and codec_dai. So we might get different values for them (0x4003 and 0x1003 for example): asoc-simple-card sound-cs42888.12: cpu : 2024000.esai / 4003 / 132000000 asoc-simple-card sound-cs42888.12: codec : cs42888 / 1003 / 24576000 asoc-simple-card sound-cs42888.12: cs42888 <-> 2024000.esai mapping ok It's pretty fair to do it for DAIFMT_INV since two dais might have differnt definitions in their drivers even though it'd be better to keep it same if we could. But for DAIFMT_MASTER bit, we should keep them identical. Otherwise, it'll make one of dai work in an incorrect mode. Thus this patch fixes it by overwriting the DAIFMT_MASTER bit of cpu_dai->fmt with the one of codec_dai->fmt since we defined DAIFMT_MASTER basing on CODEC at the first place.

[alsa-devel] Creating single-card driver for multi-codec (TLV320AIC34) board - is it possible at the machine level?
by Matt Kleffner 12 Mar '14

12 Mar '14

Hi ALSA developers, I'm developing an ALSA driver for a new board with two TLV320AIC34 chips, which to a driver is the equivalent of 4 TLV320AIC31/2/3 (TLV320AIC3X driver) codecs. The platform is OMAP4, with the OMAP as I2C master. TDM mode with one McBSP port is used, and it is desired that the four codecs appear as one 8-channel codec (clocks are shared and data buses are connected together). It is OK if there are 4 separate mixers, one for each codec. However, when starting/stopping audio all codecs should act together and audio data presented to the ALSA user interface just as with a single 8-channel sound card. My questions have two parts: one on binding together the codecs into a "single card", and another on alterations to support an external sample-clock generator. BONDING CODECS TOGETHER It is desired to write the driver at the "machine" level (ignore the external-clock modification for now), without modifying the ALSA SoC core or the TLV320AIC3X driver. Is this possible? I've searched the internet and looked through the source code, and I have the following gaps in understanding: The following TI link seems to suggest such TLV320AIC34 operation may already be possible with ALSA: http://e2e.ti.com/support/data_converters/audio_converters/w/design_notes/2… However, one of the threads pointed in that link: http://comments.gmane.org/gmane.linux.alsa.devel/84899 suggests such support is not in the ALSA SoC core or the TLV320AIC3X driver. While it is mentioned that if configured appropriately, "you'll end up with a single card", later it is mentioned that "you're probably trying to break new ground here. You're trying to bind all the CODECs together and treat them as one digital interface, currently the code does a series of point to point links multiplexed on a bus only." What does point-to-point link mean in this context? What does "you'll end up with a single card" mean if all 8 channels are not exposed in one card? If it is new ground, then what does the rx51 driver do (it is often referenced as a starting point for this type of binding effort), which interfaces to an AIC34 codec? The threads referenced are a few years old. Is it now possible to write such a driver at the machine level, or must I additionally either modify the core or write a new codec driver (as the original poster did)? ALTERATIONS TO SUPPORT AN EXTERNAL SAMPLE-CLOCK GENERATOR The sample clock is being generated by a single, I2C-configurable clock chip. So any sample-rate configuration must be sent to the clock chip. Can this be handled purely in the machine layer, or do I need to modify the AIC3X driver? I understand I need to use the regmap API to do such things, and ALSA uses this API, but I do not yet know much about it. Any pointers to documentation on doing this besides the source code are appreciated. A key newbie question on regmap (and Linux I2C) as needed by the driver the following: Does the regmap-i2c or i2c driver "own" the I2C bus so that the each device on the bus can be read from/written to via the regmap-i2c or i2c driver without the device's driver having to request-take-release the bus on each access? Thanks, - Matt

[alsa-devel] About snd_dmaengine_pcm_trigger()
by Kuninori Morimoto 12 Mar '14

12 Mar '14

Hi Mark, Lars and all I need your opinion Now, I'm working for ${LINUX}/sound/soc/sh/fsi and ${LINUX}/sound/soc/sh/rcar drirvers. These drivers are supporting DMAEngine transfer, but it is using original DMAEngine method, not using snd_dmaengine_pcm_trigger() or snd_dmaengine_pcm_register(). I was requested to use it from Mark. The reason why I couldn't use it was our DMAEngine didn't have "cyclic" tranfer support which is used on dmaengine_pcm_prepare_and_submit() But now, I created cyclic support on our DMA driver (on my local PC at this point) Then, I noticed our drivers still can't use snd_dmaengine_pcm_xxx() method. 1st, our device needs PIO tranfer support too. Current PIO/DMA transfer are sharing many methods/functions. Code will become difficult to read if it is separated forcibly. (to using snd_dmaengine_pcm_xxx()) 2nd, our device DMA ON/OFF timing has relation ship to other register settings. Unfortunately, our device is picky, it needs like this HW init setting -> DMA ON -> HW start setting It can be solved if snd_dmaengine_pcm_xxx() has callbacks, but many callbacks are needed... 3rd, our device needs special method on snd_pcm_ops int the future. From my point of view, our driver can replace to use "cyclic" DMA transfer instead of current original DMAEngine method. I guess, it is not difficult. But, using snd_dmaengine_pcm_xxx() is difficult. But, what do you think ?

[alsa-devel] [PATCH] ak4642: show error if register write fails
by Ben Dooks 11 Mar '14

11 Mar '14

The calls to snd_soc_update_bits() and snd_soc_write() return error codes if the calls fails. The ak4642 driver discards these errors which means that the user is not informed if there is an issue with the bus providing the register access.

Can't seem to compile 3.11 or 3.12 for the distro I am using (AVLInux)... tested it in Ubuntu Studio 13.10 and the quirk didn't seem to have any effect. The output of lsusb is the same, but the device doesn't show up as a sound card.

[alsa-devel] Playstation Eye won't accept rate greater than 16k, 48k device.
by Benjamin Gorman 10 Mar '14

10 Mar '14

Hello, I'm working with a playstation eye and I'm attempting to grab the raw audio in order to perform some processing using it's 4 channel microphone array. It's listed by the vendor as being a 48khz device. Using Audacity on OSX I can record 4 channels at 44,100hz. However, under linux (raspberry pi running debian) I can only record in 16khz using ALSA. arecord -vv /dev/null -r 16000 -f S16_LE -c 4 -D iec958:CARD=CameraB409241,DEV=0 /dev/null < /dev/null Any higher rate won't be accepted. I tried this using the ALSA C API and also under the PortAudio API. Both without luck. Any ideas on how to patch the driver in order to allow for 44100hz recording? The device is clearly capable of it. Regards, Benjamin The University of Dundee is a registered Scottish Charity, No: SC015096

[alsa-devel] integration into ASoC
by Maxime Ripard 10 Mar '14

10 Mar '14

Hi Liam, Mark, I have a sound IP that is part of an SoC that I'm willing to write a driver for. This IP is made of a few registers to control the sampling rate, if we're using mono/stereo, plus two fifos, one for playback, one for capture, that can be seed with data. The data are then taken, go through a DAC, and the outer interface of the IP are directly analog signals (so the DAC/ADC are directly in the SoC, and the only interface we have is plain registers). From what I understood from ASoC, you have mostly three components, the DAI, the codec and the platform that plumbers the two first together. Here, my understanding is that it's pretty much the whole three in a single IP. Should such a hardware block be handled into ASoC, and if yes, how? If not, which other framework should be used? Thanks! Maxime -- Maxime Ripard, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com

[alsa-devel] [PATCH] add Steinberg UR44 USB Audio Interface support to quirks-table.
by Cyrus Harmon 10 Mar '14

10 Mar '14

* The patch is based on Clemens Ladisch's patch to support the UR22 (http://linuxaudio.org/mailarchive/lad/2013/2/23/197831), with the device ID modified for the UR44. The patch was tested with kernel versions 3.12.11 and 3.12.12 and a PREEMPT RT-patched 3.12.12-rt kernel. Basic recording and playback appear to work. * NB: On one of the systems that I used to test the patch, I was never able to achieve xrun-free JACK performance at -p256 -n3 as I would invariably see xruns roughly once every minute. But this is a new box (Intel haswell NUC) and it seems there are many possible sources of the unacceptable latency. On an older i3 box, the performance was much better.

[alsa-devel] [PATCH 0/9] Update FLL calculations on Arizona devices
by Charles Keepax 10 Mar '14

10 Mar '14

Newer versions of the Arizona IP have several differences in the FLL configuration. The reference and synchroniser paths have slightly difference FRATIO encodings and the expanded encoding on the reference path should be used to avoid integer mode operation. This series of patches does some refactoring on the FLL configuration code, previously calculation of the FLL configuration was done before we knew whether this would be applied to reference or synchroniser path. These patches add some checks to make sure the requested clock can be accomodated and then does the calculations once we knew where they will be applied. Additionally, we add support for the encodings on the newer IP. Thanks, Charles Charles Keepax (9): ASoC: arizona: An OUTDIV of 1 is not valid, avoid this ASoC: arizona: Add defines for FLL configuration constants ASoC: arizona: Move set of OUTDIV in to arizona_apply_fll ASoC: arizona: Move calculation of FLL configuration ASoC: arizona: Don't pass Fout into arizona_calc_fll ASoC: arizona: Calculate OUTDIV first ASoC: arizona: Calculate FLL gain last mfd: arizona: Add support for new fratio encoding ASoC: arizona: Support new fratio encoding on the wm5110 rev D include/linux/mfd/arizona/registers.h | 6 +- sound/soc/codecs/arizona.c | 254 ++++++++++++++++++++++----------- 2 files changed, 171 insertions(+), 89 deletions(-) -- 1.7.2.5

[alsa-devel] [PATCH v2 1/3] ASoC: Consolidate snd_soc_register_dai() and snd_soc_register_dais()
by Lars-Peter Clausen 10 Mar '14

10 Mar '14

snd_soc_register_dais() has basically the same code as snd_soc_register_dai(), but running in a loop. The only difference is that snd_soc_register_dai() calls fmt_single_name() to generate the DAIs name and snd_soc_register_dais() calls fmt_multiple_name(). This patch pushes the check in __snd_soc_register_component() which decides whether to call snd_soc_register_dai() or snd_soc_register_dais() to snd_soc_register_dais() to decide which naming scheme to use. This allows us to remove snd_soc_register_dai(). The patch also updates snd_soc_register_dais() to unregister every DAI it finds for the component rather than trying to unregister one DAI for each DAI that was registered. Both have the same result since there won't be more DAIs than what have been registered, but the former is easier to implement.

When using table based DAPM setup there is no need to register DAPM elements for different sub-components separately. The widgets will be registered before the first sub-component is initialized, the routes are only added after the last sub-component has been initialized, meaning everything will be available when it is needed.

[alsa-devel] [PATCH] ASoC: 88pm860: Fix IO setup
by Lars-Peter Clausen 10 Mar '14

10 Mar '14

The 88pm860 is a MFD device and the CODEC driver is using the regmap struct of the parent device, hence automatic IO setup will not work and we need to manually call snd_soc_codec_set_cache_io(). The issue was introduced in commit f9ded3b2e7 ("ASoC: 88pm860x: Use regmap for I/O").

[alsa-devel] [PATCH RFC 0/2] Fix simple-card *-master DT parameter handling

[alsa-devel] [PATCH] ASoC: sam9g20_wm8731: Convert to table based DAPM setup
by Lars-Peter Clausen 10 Mar '14

10 Mar '14

Use table based setup to register the DAPM widgets and routes. This on one hand makes the code a bit shorter and cleaner and on the other hand the board level DAPM elements get registered in the card's DAPM context rather than in the CODEC's DAPM context. While we are at it also remove the snd_soc_dapm_enable_pin() in the init callback. Pins are enabled by default.

Hi, my 5.1 sound system works as 2.0 on all kernels newer than 3.2.21. Control "Channel Mode" is missing in "Alsamixer". I use the option "3stack-6ch" (module snd-hda-intel, Realtetsk codec ALC882) for kernel 3.2.21. "Alsa-info" for kernels 3.2.21 and 3.13.6 attached.

[alsa-devel] About ALSA SoC cpu/codec asymmetry
by Kuninori Morimoto 10 Mar '14

10 Mar '14

Hi Mark, Stephen, Lars Now, ALSA SoC is using "component" style, and its image is like this. ALSA SoC - platform - component (as CPU) - codec - component It is still not symmetry, and confusable. I guess this is understandable. ALSA SoC - platform - cpu - component - codec - component If we add "cpu", it needs "cpu name", same as current "codec name" on soc_bind_dai_link(). I guess it can keep compatible if it allows "NULL" name on "cpu name" at this point. (but print warning ?) What do you think ? Best regards --- Kuninori Morimoto

[alsa-devel] [PATCH 1/3] ASoC: Consolidate snd_soc_register_dai() and snd_soc_register_dais()
by Lars-Peter Clausen 09 Mar '14

09 Mar '14

snd_soc_register_dais() has basically the same code as snd_soc_register_dai(), but running in a loop. The only difference is that snd_soc_register_dai() calls fmt_single_name() to generate the DAIs name and snd_soc_register_dais() calls fmt_multiple_name(). This patch pushes the check in __snd_soc_register_component() which decides whether to call snd_soc_register_dai() or snd_soc_register_dais() to snd_soc_register_dais() to decide which naming scheme to use. This allows us to remove snd_soc_register_dai(). The patch also updates snd_soc_register_dais() to unregister every DAI it finds for the component rather than trying to unregister one DAI for each DAI that was registered. Both have the same result since there won't be more DAIs than what have been registered, but the former is easier to implement.

[alsa-devel] [PATCH] ASoC: s6105-ipcam: Convert to table based DAPM setup
by Lars-Peter Clausen 08 Mar '14

08 Mar '14

Use table based setup to register the DAPM widgets and routes. This on one hand makes the code a bit shorter and cleaner and on the other hand the board level DAPM elements get registered in the card's DAPM context rather than in the CODEC's DAPM context. While we are at it also remove the snd_soc_dapm_enable_pin() in the init callback, since pins are enabled by default. Also drop the snd_soc_dapm_sync() calls, since they are ignored by the core anyway until the card has been fully instantiated.

[alsa-devel] compress: dpcm_path_get called in wrong place
by noman pouigt 07 Mar '14

07 Mar '14

Shouldn't dpcm_path_get be called earlier ? I think it should be called earlier as happens in soc-pcm file. static int soc_compr_open_fe(struct snd_compr_stream *cstream) { if (dpcm_path_get(fe, stream, &list) <= 0) { dev_dbg(fe->dev, "ASoC: %s no valid %s route\n", fe->dai_link->name, stream ? "capture" : "playback"); In current code we open platform driver and then machine startup function gets called. After this we check for valid path which i think should happen earlier i.e. in the beginning of soc_compr_open_fe function. If you agree, then i will send a patch.

[alsa-devel] [TINYCOMPRESS][PATCH 1/1] compress: no need to set metadata before calling next_track
by Richard Fitzgerald 07 Mar '14

07 Mar '14

The metadata is mainly for MP3 gapless playback, since the MP3 audio stream does not contain enough information to enable gapless. Other audio formats do not necessarily require any additional metadata so we should allow next_track to be called without any metadata.
