Hi, please take a a look at gsequencer.org especially at: libags-audio * http://gsequencer.org/api/ags/ags-AgsPort.html gsequencer * http://gsequencer.org/api/ags/ags-AgsLineMember.html I can crash my application while modifying values of the LADSPA plugin assigned dial widget what uses atomic operations and a task engine ... Where can me read about state of Atomic Operations of linux or glibc? Me doing further investigation. bests Joël

[alsa-devel] [PATCH v2 0/2] ALSA: jack: Refactoring for jack kctls
by Jie Yang 30 Mar '15

30 Mar '15

Currently only hda will create kctls for hda jacks, for asoc, people may need create jack kctls in specific driver. Here we are introducing kctls for each jack, by creating kctls and add them to jack controls list (considering exist of combo jack). At the same time, we will report events for each control in the list. With this implement, we are no longer need hda jack specific kctls, so here also remove jack kctls for hda. Any comments are welcome.

[alsa-devel] getting the sound to work on my asus m6s00v
by Christian Gleerup 28 Mar '15

28 Mar '15

I had some problems getting the sound to work on my asus m6s00v (I think that is the model, it is a bit worn so I can't really read it) the symptoms was * on the integrated speakers, no sound at all * on the headphone speakers, sound for a very very short period that faded into nothing. with help from debianuser on freenode#alsa we managed to get it working. the option that i had to load the module with is the following: sudo modprobe snd-hda-intel model=3stack-digout the status now (perfect)... * sound on integrated speaker. * sound in headphones (disables integrated speaker output which is fine) * mic works, both for direct playback and recording * when recording it is the 'digital' channel that controls the volume of the recording level, all others Notice: I don't have OSS or pulseaudio installed. I am thinking it would be really nice if the driver automatically could detect that this option is required. this is the output from the alsa-info script http://www.alsa-project.org/db/?f=28b98a3bd1efc6a80dbd5c54b52c4472d8ea5496 let me know if I can do anything to help with this. Regards.

by Yakir Yang 27 Mar '15

27 Mar '15

We found Designware hdmi driver only support audio clock config, we can not play sound through it. To add Designware HDMI Audio support, we make those patch set: 1): fixed dw_hdmi irq bug, add irq control to suspend/resume interfaces. 2): add suspend/resume callback for dw_hdmi rockchip driver. 3): Warp irq control in functions. 4): Combine hdmi_set_clock_regenerator_n() and hdmi_regenerate_cts() 5): Adjust n/cts config order. 6): Set ncts_atomic_write & cts_manual, according to dw_hdmi document. 7): Add audio support for more display resolutions(eg. 800x600). 8): Add audio support for No-CEA display resolutions. 9): Add Audio Sample Channel Status config interfaces to dw_hdmi driver. 10): add audio clock control interfaces to dw_hdmi driver. 11): creat "dw_hdmi-audio" platform device in dw_hdmi driver. 12): add codec driver for hdmi audio, callback dw_hdmi audio config functions. 13): add sound driver for hdmi audio, creat hdmi audio sound card. 14): add dt-bings file and add hdmi_audio node to corresponding dt file. Changes in v4: -Correct phy_type assignment bug - Combine CTS3 registers setting, reduce register operate times - Combine N3 registers setting - Add hdmi audio support when monitor support audio - Give HDMI_FC_AUD_SCHNL8 an readable value - Rename "hdmi_audio_*" to "dw_hdmi_audio_*" - Replace delaywork with irq thread, and add suspend/resume interfaces, Replace "dw-hdmi-audio" with consecutive strings. - Add ".pm = &snd_soc_pm_ops," Changes in v3: - Clear Hotplug interrupts before dw_hdmi_fb_register - Wrap irq control in fucntions - Setting the .pm member instead of suspend/resume - Add ID registers parse and record - Combine hdmi_set_clock_regenerator_n() and hdmi_regenerate_cts() - Only adjust the n/cts setting order - Set ncts_atomic_write & cts_manual - Determine whether sample channel should set by desig_id. - Delete hdmi_audio_config interface and modify audio clock control functions - Remove audio_config & get_connect_status callback functions and add write/read/mod register callback functions - Keep audio format config function in dw-hdmi-audio driver and remove audio_config & get_connect_status functions, move jack control to dw-hdmi-audio completely. - Delete the operation of jack in rockchip-hdmi-audio driver, get ready to switch to simple-audio-card driver. - modify cpu-of-node to i2s-controller Changes in v2: - Add irq control to suspend/resume interfaces - Add suspend/resume support for dw_hdmi_rockchip driver - add more n/cts combinations for more display resolutions - Enable audio support for No-CEA display mode - Add audio sample channel status setting - Add audio config interfaces to dw_hdmi driver - Update the audio control interfaces - Update dw_hdmi audio control interfaces, and adjust jack report process - give "codec-name" & "codec-dai-name" an const name - remove codec-name and codec-dai-name - rename rockchip,rockchip-hdmi-audio.txt to rockchip,rockchip-dw-hdmi-audio.txt Daniel Kurtz (3): drm: bridge/dw_hdmi: adjust n/cts setting order drm: bridge/dw_hdmi: set ncts_atomic_write & cts_manual drm: bridge/dw_hdmi: add audio sample channel status setting Yakir Yang (12): drm: bridge/dw_hdmi: add irq control to suspend/resume drm: bridge/dw_hdmi: wrap irq control in fucntions drm: rockchip/dw_hdmi_rockchip: add resume/suspend support drm: bridge/dw_hdmi: add identification registers parse and record drm: bridge/dw_hdmi: combine hdmi_set_clock_regenerator_n() and hdmi_regenerate_cts() drm: bridge/dw_hdmi: add audio support for more display resolutions drm: bridge/dw_hdmi: enable audio support for No-CEA display resolutions drm: bridge/dw_hdmi: add enable/disable to dw_hdmi_audio callbacks drm: bridge/dw_hdmi: creat dw-hdmi-audio platform device ASoC: codec/dw-hdmi-audio: add codec driver for dw hdmi audio ASoC: rockchip/rockchip-hdmi-audio: add sound driver for hdmi audio dt-bindings: Add documentation for Rockchip dw-hdmi-audio .../sound/rockchip,rockchip-dw-hdmi-audio.txt | 12 + drivers/gpu/drm/bridge/dw_hdmi.c | 385 ++++++++++++++++++--- drivers/gpu/drm/bridge/dw_hdmi.h | 53 ++- drivers/gpu/drm/rockchip/dw_hdmi-rockchip.c | 16 + include/drm/bridge/dw_hdmi.h | 17 + sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/dw-hdmi-audio.c | 379 ++++++++++++++++++++ sound/soc/codecs/dw-hdmi-audio.h | 74 ++++ sound/soc/rockchip/Kconfig | 9 + sound/soc/rockchip/Makefile | 2 + sound/soc/rockchip/rockchip_hdmi_audio.c | 169 +++++++++ 12 files changed, 1076 insertions(+), 46 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/rockchip,rockchip-dw-hdmi-audio.txt create mode 100644 sound/soc/codecs/dw-hdmi-audio.c create mode 100644 sound/soc/codecs/dw-hdmi-audio.h create mode 100644 sound/soc/rockchip/rockchip_hdmi_audio.c -- 2.1.2

[alsa-devel] [PATCH] ASoC: atmel_pcm: use endian agnostic IO accessors
by Ben Dooks 26 Mar '15

26 Mar '15

The atmel-pcm.h is using __raw_readl and __raw_writel for IO accessors which do not work if the processor is in big endian mode (the peripheral will still expect data in little endian format). Note, I do not think this is being used in the AVR32 which would require a different fix (possible after atmel_io.h is merged). This has not been run-tested as I do not have a board with an audio code on.

[alsa-devel] [PATCH] ASoC: davinci-evm: drop un-necessary remove function
by Jyri Sarha 26 Mar '15

[alsa-devel] Add AZX_DCAPS_I915_POWEREWELL on SKL is OK?
by Yang, Libin 26 Mar '15

26 Mar '15

Hi Takashi, Is it OK to add AZX_DCAPS_I915_POWEREWELL for SKL in hda_intel.c? SKL HDA controller is not in powerwell domain. But its HDMI codec is in the domain. My understanding is if the flag is added here, it means the controller is in the domain. But I can't find a good place to add a flag to indicate the HDMI codec need the power domain. Regards, Libin

[alsa-devel] RawMIDI behaviour with MidiFace 4x4
by Kalvas, Taneli 25 Mar '15

25 Mar '15

Dear All, I am developing a patch librarian for a synthesizer. Because the communication happens with Midi sysex and timing is not relevant I chose RawMIDI interface and not the alsa sequencer. The problem I have encountered is that writing to the midi port with snd_rawmidi_write() seems to broken. The function accepts any size of data block and claims to have sent everything. In reality only a part of the message is sent. For a large block size I can see the activity light blinking for fraction of a second. This happens both in blocking and non-blocking mode. I would expect the snd_rawmidi_write() to accept only a part of the message. My hardware is Miditech Midiface 4x4, a USB midi interface: $ cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xe0610000 irq 45 1 [MIDI4x4 ]: USB-Audio - MIDI4x4 MIDIPLUS MIDI4x4 at usb-0000:00:14.0-1, full speed usbid: 1acc:1a0b My alsa is quite recent (aplay shows version 1.0.27.2), I am running Ubuntu with 3.13.0-39-generic kernel. I have tested the system by connecting the output port to an input port on the hardware and having another program output the received bytes on stdout. My observations: - As long as the buffer size is 276 bytes or less it gets sent ok - Larger buffer sizes cause corruption and roughly 300 bytes of received. - Alsa reports midi ring buffer size of 4096. - snd_rawmidi_status_get_xruns() on both ends reports 0 errors. - If I write N=128 byte blocks and usleep for 352*N after each write, everything works ok. Is this due to hardware incompatibility with alsa driver or what is going on? Is there a way to connect two programs via a virtual RawMIDI port so that I could test without using the hardware? Any other diagnostics that I could do? My test programs: write.cpp: int main( void ) { int intstatus; snd_rawmidi_t *midiout; if( (intstatus = snd_rawmidi_open(NULL, &midiout, "hw:1,0,1", 0)) ) { std::cerr << "unable to open MIDI out port: " << snd_strerror(intstatus) << "\n"; exit( 1 ); } int N = 3000; // 276 bytes gets through ok. unsigned char msg[N]; for( int a = 0; a < N; a++ ) { msg[a] = a % 0x80; } msg[0] = 0xF0; msg[N-1] = 0xF7; ssize_t wrstatus; if( (wrstatus = snd_rawmidi_write(midiout, msg, N)) < 0 ) { std::cerr << "unable to write MIDI port: " << snd_strerror(wrstatus) << "\n"; return( -1 ); } std::cout << "write status = " << wrstatus << "\n"; if( (intstatus = snd_rawmidi_drain( midiout )) ) { std::cerr << "unable to drain: " << snd_strerror(intstatus) << "\n"; exit( 1 ); } // Sleep for the amount of time needed for transfer + 10 % extra + 100 ms usleep( 352*N + 100000 ); snd_rawmidi_status_t *stat; snd_rawmidi_status_malloc( &stat ); snd_rawmidi_status( midiout, stat ); int err = snd_rawmidi_status_get_xruns( stat ); std::cout << "xruns = " << err << "\n"; snd_rawmidi_close( midiout ); return( 0 ); } -------------------- read.cpp: bool quit = false; void signal_int( int ) { quit = true; } int main( void ) { int mode = SND_RAWMIDI_NONBLOCK; int intstat; std::string portname = "hw:1,0,0"; //std::string portname = "virtual"; snd_rawmidi_t* midiin; if( (intstat = snd_rawmidi_open(&midiin, NULL, portname.c_str(), mode)) < 0 ) { std::cerr << "unable to open MIDI port " << portname << ": " << snd_strerror(intstat) << "\n"; exit( 1 ); } int count = 0; unsigned char buf[1]; std::cout << std::dec << std::setfill(' ') << std::setw(6) << count << " "; signal( SIGINT, signal_int ); while( !quit ) { int read = snd_rawmidi_read( midiin, buf, 1 ); if( read == 0 || read == -EBUSY || read == -EAGAIN ) { usleep( 320 ); continue; } else if( read < 0 ) { std::cerr << "unable to read MIDI port" << portname << ": " << snd_strerror(read) << "\n"; exit( 1 ); } std::cout << std::hex << std::setfill('0') << "0x" << std::setw(2) << (int)buf[0] << " " << std::flush; count++; if( count % 8 == 0 ) { std::cout << "\n"; std::cout << std::dec << std::setfill(' ') << std::setw(6) << count << " " << std::flush; } } snd_rawmidi_status_t *stat; snd_rawmidi_status_malloc( &stat ); snd_rawmidi_status( midiin, stat ); int err = snd_rawmidi_status_get_xruns( stat ); std::cout << "\nxruns = " << err << "\n"; snd_rawmidi_close( midiin ); return( 0 ); } Thanks.

[alsa-devel] [PATCH resend] ASoC: fsl-ssi: Fix bitclock calculation for master mode
by Marc Kleine-Budde 25 Mar '15

25 Mar '15

From: Sascha Hauer <s.hauer(a)pengutronix.de> in fsl_ssi_set_bclk we are looking for the best divider by iterating over all possible dividers. The divider is in the range 1..256, so make this clear by using 'div' as name for the loop counter and iterate from 1 to 256 instead of 0 to 255. This makes obvious that tmprate is calculated wrong, it has to be freq * factor * div, not freq * factor * (i + 2).

[alsa-devel] Missing beep controls for Via HDA codec (snd_hda_codec_via)

I've filled out Via's datasheet-request form [2], but I don't know how likely that is to be accepted. Does anyone have a VT1802 datasheet that they're allowed to share (or some free time to fill in Via beep support on their own)? Or am I barking up the wrong tree? My only previous experience with this code-base was a beep-tweak for a previous box's Realtek chip [3], but I love my beeps and am happy to poke around with a datasheet until I get this working ;). Maybe folks with more experience can just guess the right code without needing to see specs for the VT1802?

[alsa-devel] [PATCH v3 0/2] ALSA: jack: Refactoring for jack kctls
by Jie Yang 25 Mar '15

25 Mar '15

Currently only hda will create kctls for hda jacks, for asoc, people may need create jack kctls in specific driver. Here we are introducing kctls for each jack, by creating kctls and add them to jack controls list (considering exist of combo jack). At the same time, we will report events for each control in the list. With this implement, we are no longer need hda jack specific kctls, so here also remove jack kctls for hda. Changes in v3: 1. replace bit index with bit mask in jack_kctl; 2. add exception for SND_JACK_HEADSET and SND_JACK_AVOUT, only create one jack kctl for these two combo jacks, respectively. 3. add NULL check, mem kfree, and fix some potential risk. Change in v2: 1. define jack_kctl struct, and put jack kctl related stuff there; 2. add a patch to remove the existing controls for HDA jack.

[alsa-devel] [PATCH v3] ASoC: davinci-mcasp: Set rule constraints if implicit BCLK divider is used
by Jyri Sarha 24 Mar '15

24 Mar '15

Set rule constraints to allow only combinations of sample-rate, sample-format, and channels counts that can be played/captured with reasonable sample-rate accuracy. The logic with tdm-slots and serializers (=i2s data wires) goes like this: The first wire will take all channels up to number of tdm-slots, before following wires (if any) are used. If the first wire is used fully, the remaining wires share the same clocks and the divider can be calculated for the first wire. Also, takes the number of tdm-slots into account when implicitly selecting the BLCK divider. Signed-off-by: Jyri Sarha <jsarha(a)ti.com> --- Previous version of the patch: http://mailman.alsa-project.org/pipermail/alsa-devel/2015-March/089319.html Since v2 I changed the SNDRV_PCM_HW_PARAM_SAMPLE_BITS rule in the to SNDRV_PCM_HW_PARAM_FORMAT rule. Somehow the constraints with a SNDRV_PCM_HW_PARAM_SAMPLE_BITS rule using snd_interval_list() converged to an empty set when ever I tried to play a format that could not pass the rule with any channel count or rate, resulting all too familiar assertion in alsa-lib. However, the direct tampering with SNDRV_PCM_HW_PARAM_FORMAT mask appears to work as it should. In addition to SAMPLE_BITS- to FORMAT-rule change I optimized the rate rule a bit so that it does not try the rates that are outside current range. According to my tests this does not affect the behavior in any other way but slightly speeds up the decision making. sound/soc/davinci/davinci-mcasp.c | 207 ++++++++++++++++++++++++++++++++++++-- 1 file changed, 197 insertions(+), 10 deletions(-) diff --git a/sound/soc/davinci/davinci-mcasp.c b/sound/soc/davinci/davinci-mcasp.c index d40b392..76156d18 100644 --- a/sound/soc/davinci/davinci-mcasp.c +++ b/sound/soc/davinci/davinci-mcasp.c @@ -27,6 +27,7 @@ #include <linux/of_platform.h> #include <linux/of_device.h> #include <linux/platform_data/davinci_asp.h> +#include <linux/math64.h> #include <sound/asoundef.h> #include <sound/core.h> @@ -65,6 +66,11 @@ struct davinci_mcasp_context { bool pm_state;

Currently GPIO4 is hardcoded to output the pll-lock signal. Unfortunately this is after the pll-out GPIO is configured which is selectable in the device tree. Therefore it is not possible to use GPIO4 for pll-out. Therefore this patch removes the configuration of GPIO4.

I am also stuck with the same problem. I am sure ALSA experts can help here. What i want to know is how to set the dapm widgets in open embedded? Is it alsa.conf or asound.conf ? I need to set something like this: amixer cset name="LEFT MIXER DAC" 1 Using amixer i am able to playback but i don't know how can i modify conf file to have this dapm widgets associated with a device.

[alsa-devel] [RFC][PATCH 00/11] digi00x: new driver for Digidesign 002/003 family
by Takashi Sakamoto 24 Mar '15

24 Mar '15

This patchset adds an experimental driver for Digidesign 002/003 family. If you have any models, please test with this driver and report the result. Currently, this driver correctly supports these major functionalities: (as long as I tested) * PCM sample capture * MIDI messages capture * MIDI messages playback And functionalities which need to be tested: * streaming with S/PDIF, ADAT and work clock source * MIDI device control And includes a bug which should be fixed: * PCM sample playback For a driver for these models, there was a preceding implementation by Robin Gareus and Damien Zammit. [alsa-devel] draft -- ALSA firewire + digi003 http://mailman.alsa-project.org/pipermail/alsa-devel/2013-January/058177.ht… This patchset includes their implementation, called-as double-oh-three, to multiplex PCM samples into CIP packet. As long as I test, their implementation may includes any bugs and this driver still causes noisy sound in several cases, while I confirm to get the same data block pattern which Robin explains. http://gareus.org/wiki/digi003 If you interested in this bug and tries to fix it, my packet dump may be helpfull. Please see: http://subversion.ffado.org/wiki/digi003rack * 96khz-24bit-1ch.log (27.5 kB) * 44khz-24bit-1ch.log (49.8 kB) * 44khz-24bit-2ch.log (49.8 kB) And DKMS package is available on my github repository. https://github.com/takaswie/snd-firewire-improve Takashi Sakamoto (11): ALSA: digi00x: add skelton for Digi 002/003 device driver ALSA: digi00x: add streaming functionality ALSA: digi00x: add proc node for clock status ALSA: digi00x: add PCM functionality ALSA: digi00x: add MIDI functionality ALSA: digi00x: add hwdep interface ALSA: digi00x: support unknown asynchronous message ALSA: digi00x: support MIDI ports for device control ALSA: firewire-lib: allows to implement external MIDI callback function digi00x: improve MIDI capture/playback ALSA: digi00x: apply double-oh-three algorism to multiplex PCM samples include/uapi/sound/asound.h | 3 +- include/uapi/sound/firewire.h | 1 + sound/firewire/Kconfig | 10 + sound/firewire/Makefile | 1 + sound/firewire/amdtp.c | 30 ++- sound/firewire/amdtp.h | 5 + sound/firewire/digi00x/Makefile | 3 + sound/firewire/digi00x/digi00x-hwdep.c | 192 ++++++++++++++ sound/firewire/digi00x/digi00x-midi.c | 199 +++++++++++++++ sound/firewire/digi00x/digi00x-pcm.c | 336 +++++++++++++++++++++++++ sound/firewire/digi00x/digi00x-proc.c | 71 ++++++ sound/firewire/digi00x/digi00x-protocol.c | 361 +++++++++++++++++++++++++++ sound/firewire/digi00x/digi00x-stream.c | 398 ++++++++++++++++++++++++++++++ sound/firewire/digi00x/digi00x.c | 179 ++++++++++++++ sound/firewire/digi00x/digi00x.h | 126 ++++++++++ 15 files changed, 1907 insertions(+), 8 deletions(-) create mode 100644 sound/firewire/digi00x/Makefile create mode 100644 sound/firewire/digi00x/digi00x-hwdep.c create mode 100644 sound/firewire/digi00x/digi00x-midi.c create mode 100644 sound/firewire/digi00x/digi00x-pcm.c create mode 100644 sound/firewire/digi00x/digi00x-proc.c create mode 100644 sound/firewire/digi00x/digi00x-protocol.c create mode 100644 sound/firewire/digi00x/digi00x-stream.c create mode 100644 sound/firewire/digi00x/digi00x.c create mode 100644 sound/firewire/digi00x/digi00x.h -- 2.1.0

[alsa-devel] [PATCH 0/7] Yet more HD-audio restrucruing
by Takashi Iwai 23 Mar '15

23 Mar '15

Hi, this is the patchset I mentioned in the previous post -- moving some HD-audio core stuff into sound/hda/ directory. As of now, only the codec drivers are split to sound/hda/. The legacy bus (controller) driver still remains almost intact, but the split of the core controller driver is also planned, and will be finished hopefully before 4.1 merge window. The original patches are found in topic/hda-core branch of sound git tree. The patches posted here are the ones rebased on top of the previous widget PM patches, and found in test/hda-core branch. Once when the widget PM patches get merged, I'll adjust this patchset on top of it.

[alsa-devel] simplify simple-card
by Kuninori Morimoto 23 Mar '15

23 Mar '15

Hi Mark, all I want to create new sound card driver which supports DAPM. But I can't use simple-card driver for this purpose because DT binding issue. I guess, this new sound card can use/share simple-card functions. OTOH, simple-card is not "simple" today :( Basically, main purpose of simple-card / new sound card is binding CPU/Codec settings to ALSA SoC framework. But we have many pattern for it. From DT bindings point of view, we can/should use same DT bindings for same settings. Now, simple-card is supporting - single CPU/Codec - multi CPU/Codec - more feature... My opinion is that complex code has un-understandable bug. So, how about simplify simple-card, what do you think about this idea ? We separate current simple-card to common parts, and, simple-card specific parts. basically, common parts controls DT bindings and ALSA SoC settings. sound card specific parts cares each own feature. I don't know about naming, but these audio card can use same bindings via common functions. - common : basic common functions - simple-audio-card : existing driver, keep as-is for compatible reason - single-audio-card : single CPU/Codec sound card. simplified from simple-audio-card - multi-audio-card : multi CPU/Codec sound card. simplified from simple-audio-card - fixrate-audio-card : new sound card same as single-audio-card, but it needs sampling-rate-convert via DAPM, - chain-audio-card : DAPM card (?) - .... My idea is taht we can replace current "simple-audio-card" to "single-audio-card", or, "simple-audio-card" to "multi-audio-card" on DT. Best regards --- Kuninori Morimoto

[alsa-devel] [PATCH 1/2] [resend] snd-waveartist: Introduce Rockwell WaveArtist RWA010 driver
by Ondrej Zary 22 Mar '15

22 Mar '15

This is a new ALSA driver driver for Rockwell WaveArtist RWA010 chips found on some (rare) ISA sound cards, such as DCS Multimedia S717. I wasn't able to get the old OSS WaveArtist driver to work with my card but it was a great source of information about the chip (as the full datasheet is not available - only a brief one and a design guide). However, the OSS driver only supports few of the mixer registers so I had to install the card in Windows and dump mixer registers while changing the mixer settings. Then tried what the rest of the registers do and the result is a fully working mixer which even supports more controls than the Windows driver. Someone with a NetWinder can add support for it to this driver and then remove the old OSS one.

For a codec such as the SGTL5000 I would connect a clock, which is running all the time. If you take a look at the driver, it enables the clock at probe and leaves it running as long as the driver is loaded. But AM335x has CLKOUT1,2 outputs as well. They are not high quality clocks, but can be enabled/disabled. >> This will not work in mainline kernel.

As I said, this is not going to work in upstream kernel. The McASP is not even powered up during probe time anymore. It is only powered up when it is needed, this means that you will not have clocks for the codec coming from McASP pin. The driver is not designed to support such a use case, when you use one of it's clock as a master clock for external chip. In other words the McASP driver is not a clock driver. It might be possible to create a clock driver on top of the McASP driver as child, but it is really something which should not be supported. > >> How do you configure the frequency of the AHCLKX/R, this hack only enables it, >> so you are going to have _some_ clock going out. > > The frequency is the 12 MHz (I think) I get out from AHCLKX without > any further configuration; I have not investigated changing that > frequency as it suited my needs.

It works in other HW because the designers connected the SGTL5000's MCLK to a clock source which can be controlled or it is running all the time. In your case the designers chosen a clock line, which is not working as 'normal' clock. > Is it safe to assume set_sysclk is always going to adjust the I2S MCLK > speed? Please pardon my crude questions, I'm not deeply familiar with > the structure of ALSA. With the setclkdiv/sysclk you can configure the AHCLKX direction and configure the divider to be used to generate the clock which goes out, or to divide down the clock which is coming in. Another issue this hack has is: what happens if for some reason the SGTL5000 driver loads first? McASP will not enable the AHCLKX so the codec driver will fail reading the CHIP_ID and fails to load. You need to provide a dummy clock node to the codec, so that will not fail, but you will not have the MCLK. > I'll reformat the patches and try from a mainline kernel when I get > some spare time. I'm not sure if this can be accepted, sorry. It is really a hack and there are too many corner cases where the system can fail. -- Péter

[alsa-devel] [PATCH] ASoC: Intel: remove misleading DMA error messages on Baytrail platforms
by Pierre-Louis Bossart 22 Mar '15

22 Mar '15

During probe, the Baytrail audio driver reports errors such as: [44.172040] baytrail-pcm-audio baytrail-pcm-audio: error: invalid DMA engine 0 [44.172137] baytrail-pcm-audio baytrail-pcm-audio: sst_dma_new failed Those error messages are misleading, there is no error since the DMA is explicitly not configured for Baytrail.

[alsa-devel] [PATCH 1/2] ALSA:ControlName.txt: Add 'Analogue' as a prefix for volume controls
by Howard Mitchell 21 Mar '15

21 Mar '15

Currently 'Playback Volume' is the correct way to express an analogue volume control. However, this control name has initialisation defaults applied when using 'alsactl restore' and in some cases this is not appropriate. An example would be a control that has a selection of 0db and -6dB of gain that is intended to set the fullscale ouput voltage of a DAC. The TI pcm512x family of DAcs have such a control. In this case the device/driver reset defaults are preferred.

[alsa-devel] [PATCH 0/4] More aggressive PM for HD-audio
by Takashi Iwai 21 Mar '15

21 Mar '15

Hi, here is a patchset for supporting more aggressive PM for HD-audio. This allows to change the power state of each widget more dynamically with jack and stream states. It's activated only when the codec driver (or via sysfs or f/w patch) sets codec->power_mgmt flag. In theory, this should work for the recent Realtek codecs, but currently I have no machine for test. David, could you or your team check whether this works for ALC282 or such?

[alsa-devel] [RFC][PATCH 00/13] alsa-tools: libhinawa for control applications of FireWire devices
by Takashi Sakamoto 20 Mar '15

20 Mar '15

This is RFC for a new library into alsa-tools. ALSA in Linux 3.16 or later extends a support for FireWire sound devices. Currently ALSA drivers supports streaming functionality only, while most of these devices require software implementation to control its internal DSP. The way to achieve this is to transfer byte sequence to the unit and wait byte sequence which the unit transfers if required. This library, libhinawa, just support these operations, nothing others. The supported types of transactions are: - IEEE 1394 read transaction - IEEE 1394 write transaction - IEEE 1394 lock transaction - IEC 61883-1 FCP transaction - Echo Fireworks transaction (with a help of snd-fireworks kernel driver) - Dice notification (with a help of snd-dice kernel driver) To help new developers, this library supports GObject Introspection for language bindings. The main logic of applications can be written with preferred languages such as Python, Ruby, Perl and so on. In the end of this patchset, some Python scripts with Gtk+, Qt4 and Qt5 are committed as samples. This is my first development with GNU Autotools, GLib/GObject and GObject Introspection. Furthermore, I'm a beginner of FireWire subsystem programming. I'm happy to receive your comments, especially: - the way to write Linux version dependency in configure.ac - the way of libtool versioning - the value of poll timeout in fw_unit/snd_unit - the value of thread condition timeout in fw_fcp/snd_dice/snd_efw - improvements of 'unit_query' object - any programming mistakes (threading and so on...) Regards Takashi Sakamoto (13): libhinawa: add build definitions libhinawa: add hinawa context libhinawa: support GTK-Doc to generate references libhinawa: add 'fw_unit' object as a listener for FireWire unit libhinawa: support GObject Introspection for language bindings libhinawa: add 'fw_resp' object as a responder for FireWire transaction libhinawa: add 'fw_req' object as requester for FireWire transaction libhinawa: add 'fw_fcp' object as a helper of FCP transaction libhinawa: add 'snd_unit' object as a listener for ALSA FireWire devices libhinawa: add 'snd_dice' object as a helper for Dice notification libhinawa: add 'snd_efw' object as a helper for EFW transaction libhinawa: add 'unit_query' as a query for ALSA FireWire devices libhinawa: add sample scripts Makefile | 2 +- libhinawa/AUTHORS | 1 + libhinawa/COPYING | 504 ++++++++++++++++++++++++++++ libhinawa/ChangeLog | 5 + libhinawa/Makefile.am | 6 + libhinawa/NEWS | 0 libhinawa/README | 30 ++ libhinawa/autogen.sh | 11 + libhinawa/configure.ac | 68 ++++ libhinawa/doc/Makefile.am | 2 + libhinawa/doc/reference/Makefile.am | 46 +++ libhinawa/doc/reference/hinawa-docs.sgml | 47 +++ libhinawa/doc/reference/version.xml.in | 1 + libhinawa/samples/gtk3.py | 190 +++++++++++ libhinawa/samples/qt4.py | 206 ++++++++++++ libhinawa/samples/qt5.py | 192 +++++++++++ libhinawa/samples/run.sh | 15 + libhinawa/src/Makefile.am | 97 ++++++ libhinawa/src/backport.h | 41 +++ libhinawa/src/fw_fcp.c | 282 ++++++++++++++++ libhinawa/src/fw_fcp.h | 58 ++++ libhinawa/src/fw_req.c | 265 +++++++++++++++ libhinawa/src/fw_req.h | 56 ++++ libhinawa/src/fw_resp.c | 232 +++++++++++++ libhinawa/src/fw_resp.h | 51 +++ libhinawa/src/fw_unit.c | 343 +++++++++++++++++++ libhinawa/src/fw_unit.h | 52 +++ libhinawa/src/hinawa_context.c | 60 ++++ libhinawa/src/hinawa_context.h | 10 + libhinawa/src/internal.h | 31 ++ libhinawa/src/snd_dice.c | 195 +++++++++++ libhinawa/src/snd_dice.h | 53 +++ libhinawa/src/snd_efw.c | 315 ++++++++++++++++++ libhinawa/src/snd_efw.h | 54 +++ libhinawa/src/snd_unit.c | 548 +++++++++++++++++++++++++++++++ libhinawa/src/snd_unit.h | 69 ++++ libhinawa/src/unit_query.c | 116 +++++++ libhinawa/src/unit_query.h | 48 +++ 38 files changed, 4301 insertions(+), 1 deletion(-) create mode 100644 libhinawa/AUTHORS create mode 100644 libhinawa/COPYING create mode 100644 libhinawa/ChangeLog create mode 100644 libhinawa/Makefile.am create mode 100644 libhinawa/NEWS create mode 100644 libhinawa/README create mode 100755 libhinawa/autogen.sh create mode 100644 libhinawa/configure.ac create mode 100644 libhinawa/doc/Makefile.am create mode 100644 libhinawa/doc/reference/Makefile.am create mode 100644 libhinawa/doc/reference/hinawa-docs.sgml create mode 100644 libhinawa/doc/reference/version.xml.in create mode 100755 libhinawa/samples/gtk3.py create mode 100755 libhinawa/samples/qt4.py create mode 100755 libhinawa/samples/qt5.py create mode 100755 libhinawa/samples/run.sh create mode 100644 libhinawa/src/Makefile.am create mode 100644 libhinawa/src/backport.h create mode 100644 libhinawa/src/fw_fcp.c create mode 100644 libhinawa/src/fw_fcp.h create mode 100644 libhinawa/src/fw_req.c create mode 100644 libhinawa/src/fw_req.h create mode 100644 libhinawa/src/fw_resp.c create mode 100644 libhinawa/src/fw_resp.h create mode 100644 libhinawa/src/fw_unit.c create mode 100644 libhinawa/src/fw_unit.h create mode 100644 libhinawa/src/hinawa_context.c create mode 100644 libhinawa/src/hinawa_context.h create mode 100644 libhinawa/src/internal.h create mode 100644 libhinawa/src/snd_dice.c create mode 100644 libhinawa/src/snd_dice.h create mode 100644 libhinawa/src/snd_efw.c create mode 100644 libhinawa/src/snd_efw.h create mode 100644 libhinawa/src/snd_unit.c create mode 100644 libhinawa/src/snd_unit.h create mode 100644 libhinawa/src/unit_query.c create mode 100644 libhinawa/src/unit_query.h -- 2.1.0

[alsa-devel] Can iMX6SL supports different sampling rate for different SSIs?
by Xuebing Wang 20 Mar '15

20 Mar '15

Nicolin, Thank you very much for your always help. I am using 3 SSIs (as I2S master mode) on iMX6SL for 3 different codec. 1) If I read iMX6SL reference manual correctly, I am deriving SSI sys_clock from pll4. -- pll4 = Fref * (DIV_SELECT + NUM/DENOM) ** I am using a value of 786.432000 MHz -- pll4_main_clk = pll4 / (PLL_AUDIOn: POST_DIV_SELECT) / CCM_ANALOG_MISC2n: MSB:LSB ** I am using a value of 196.608 MHz -- SSI1_CLK_ROOT = pll4_main_clk / (CS1CDR: ssi1_clk_pred) / CS1CDR: ssi1_clk_podf ** I am using a value of 3.072 MHz (for 48k sampling rate) 2) As pll4_main_clk is global for all 3 SSIs, I think that we can *not* use 8k for ssi1 and 44.1k for ssi2, right? Because 8k and 44.1k requires different pll4 clock, right? -- However, as 48k, 32k, 16k, 8k can use same pll4, thus different SSI can use different sampling rate in this subset (48k, 32k, 16k, 8k). -- Same principle applies for 44.1k, 22.050, 11.025 subset of sampling rates. Is my understanding correct? -- Xuebing

[alsa-devel] [PATCH v2.1] ASoC: davinci-mcasp: Set rule constraints if implicit BCLK divider is used
by Jyri Sarha 19 Mar '15

19 Mar '15

Set rule constraints to allow only combinations of sample-rate, sample-bits, and channels that can be played/captured with reasonable sample-rate accuracy. The logic with tdm-slots and serializers (=i2s data wires) goes like this: The first wire will take all channels up to number of tdm-slots, before following wires (if any) are used. If the first wire is used fully, the remaining wires share the same clocks and the divider can be calculated for the first wire. Also, takes the number of tdm-slots into account when implicitly selecting the BLCK divider.

[alsa-devel] [PATCH] ASoC: Intel: remove misleading DMA error messages on Baytrail platforms
by Pierre-Louis Bossart 19 Mar '15

19 Mar '15

During probe, the Baytrail audio driver reports errors such as: [44.172040] baytrail-pcm-audio baytrail-pcm-audio: error: invalid DMA engine 0 [44.172137] baytrail-pcm-audio baytrail-pcm-audio: sst_dma_new failed Those error messages are misleading, there is no error since the DMA is explicitly not configured for Baytrail. Add a test to remove DMA error checks when DMA is not configured and return silently.

[alsa-devel] [PATCH] ALSA: jack: create jack kcontrols for every jack input device
by Jie Yang 19 Mar '15

19 Mar '15

From: Liam Girdwood <liam.r.girdwood(a)linux.intel.com> Currently the ALSA jack core registers only input devices for each jack registered. These jack input devices are not readable by userspace devices that run as non root. This patch adds support for additionally registering jack kcontrol devices for every input jack registered. This allows non root userspace to read jack status.

First off, please send the patches with git send-email so people can comment on them. This will not work in mainline kernel. The McASP is turned off when it is not in use (no audio activity) so the AHCLKX/R is not going to be there on the ball output. How do you configure the frequency of the AHCLKX/R, this hack only enables it, so you are going to have _some_ clock going out. You should be using set_clkdiv and set_sysclk calls from the machine driver to configure the AHCLKX (we do not have AHCLKR supported in the driver ATM). -- Péter

Please submit patches using the process in SubmittingPatches, you need to work against current development versions of the kernel rather than an old vendor kernel.

[alsa-devel] [PATCH v2] ASoC: davinci-mcasp: Set rule constraints if implicit BCLK divider is used
by Jyri Sarha 19 Mar '15

19 Mar '15

Set rule constraints to allow only combinations of sample-rate, sample-bits, and channels that can be played/captured with reasonable sample-rate accuracy. The logic with tdm-slots and serializers (=i2s data wires) goes like this: The first wire will take all channels up to number of tdm-slots, before following wires (if any) are used. If the first wire is used fully, the remaining wires share the same clocks and the divider can be calculated for the first wire. Also, takes the number of tdm-slots into account when implicitly selecting the BLCK divider. Signed-off-by: Jyri Sarha <jsarha(a)ti.com> --- I hope the logic with tdm-slots and serializers is now correct. I do not have HW to test multiple serializers case, so please review davinci_mcasp_hw_rule_channels() extra carefully.

Hello, First of all, since this is my first message I hope am not mistaken reporting this two issues about this piece of hardware (I was pointed here by alsa irc support channel) and bug tracker url does not seem to work, so I decided to post it here. Problem: Errors with mixer controls, breaking alsamixer, and not working 7.1 support.

[alsa-devel] bug in alsa-plugins: #if SND_PCM_EXTPLUG_VERSION wrong
by Ethan Grammatikidis 18 Mar '15

18 Mar '15

in alsa-plugins 1.0.28 and 1.0.29, mix/*.c contain the following line: #if SND_PCM_EXTPLUG_VERSION >= 0x102 that 0x102 needs to be 0x10002. i have alsa-lib 1.0.26 installed. its headers define SND_PCM_EXTPLUG_VERSION to 0x10001, corresponding to version number 1.0.1. that #if effectively tests for >= 0.1.2, so attempting to build alsa-plugins 1.0.28 or 1.0.29 results in a long list of errors. SND_CHMAP_MONO, SND_CHMAP_FL, etc are undeclared and snd_pcm_chmap_query_t is an unknown type. in alsa-plugins 1.0.26 SND_PCM_EXTPLUG_VERSION is not tested. i didn't look at 1.0.27 reporting here because the bug tracker is down. -- Wir mussen wissen, wir werden wissen.

[alsa-devel] Support two wm8962 codec in i.mx6 board.
by Shawn Embedded 18 Mar '15

18 Mar '15

Hello everyone, I'm new to ALSA. I have a question here. Now there is a wm8962 on the i.mx6 board, running well, and we want to add an extra wm8962 to the board, connected to i.mx6 on another SSI port through a different i.mx6's AUDMUX port. The two wm8962 will work independently completely, at the same time possiblly. Before sending this mail to the list, I've already googled some materials about my requirements. I've found there is a structure named "struct snd_soc_aux_dev". For my applicantion, if I want to support another wm8962, could I can use this structure for my intention please? But in this link http://www.spinics.net/lists/alsa-devel/msg40127.html , it's said that This makes possible to register auxiliary dailess codecs in a machine driver. Term dailess is used here for amplifiers and codecs without DAI or DAI being unused. then, does it mean that I couldn't use this structure for my application? Or, I should declare another structure "struct snd_soc_card" for the second wm8962, just as the now-working wm8962? or other ways? In fact, I'm a little confused if I could declare two structure snd_soc_card at the same? If it's OK, what should I do next to meet my requirement? Could anyone give me any guidance on this? Any links, and materials will also be much appreciated. Thank you in advance. ------------------- Best Regards, Shawn

[alsa-devel] pcm512x driver: Mixer control naming issue
by Howard Mitchell 17 Mar '15

17 Mar '15

Hi, As you may be aware the Raspbian distribution for the RaspberryPi has recently been upgraded to kernel version 3.18. It was previously at version 3.12. This has had the unfortunate side effect that users of the PCM5122 DAC have found that the output volume has been significantly reduced. The issue is related to this commit <https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit…> which adds support for a couple of analogue gain controls. One control (Playback Volume) sets a gain of either 0db or -6dB and is intended to set the full scale output at 2Vrms or 1Vrms respectively. The other (Playback Boost Volume) provides a boost of +0.8dB. The hardware reset value of both of these gain controls is 0dB, however, in the Raspbian distribution 'Playback Volume' is being defaulted to -6dB. After some investigation I figured out that this was caused by the alsa restore mechanism. If '/var/lib/alsa/asound.state' doesn't exist or there is no saved state for a particular control then the defaults in '/usr/share/alsa/init/default' are used. In this file the default for a control named 'Playback Volume' is -20dB which is forcing the control to it's minimum value of -6dB. This seems like incorrect behaviour for something that is essentially an implementation detail, i.e. a choice that should be made by the board designer not the end user. Therefore I'd like to see what you think of the following suggestions (which I'd be more than happy to implement and submit patches for): * Either change the names of these controls to something that's not affected by the alsa restore mechanism, * or remove them as mixer controls, but make them accessible some other way - e.g. device tree.

Hi Mark, These are Braswell machine driver fixup patches. Jin Yao (2): 1) ASoC: Intel: Add suspend_pre and resume_post for Braswell snd_soc_card 2) ASoC: Intel: move the jack creation to Braswell machine driver For 1), it requires following dependency patches to build: ASoC: rt5670: Add IRQ function ASoC: rt5670: export jack suspend/resume APIs For 2), it requires following dependency patch to build: ASoC: Allow to register jacks at the card level These dependency patches have been integrated in for-next branch but not in intel branch.

[alsa-devel] HD-audio restructuring (and future changes)
by Takashi Iwai 16 Mar '15

16 Mar '15

Hi, I now merged the branches topic/hda-bus and topic/hda-unbind into for-next branch that is targeted for 4.1 kernel. They are the changes of HD-audio I posted in the last month, moving the HD-audio binding to standard bus and its relevant fixes. At this moment, there should be no big visible (nor audible) changes. It's merely an internal structure change. Now you see more sysfs entries and controls, but the basic functionality via API remains identical. Also, hda-emu was updated together with this merge. Let me know if you hit any issue with these updates. About the future plan: there are already more pending changes for HD-audio and I'd like to merge them for 4.1, too. Namely, many basic HD-audio codes are split to a smaller core library in sound/hda, so that we can build the upcoming ASoC HD-audio driver with a smaller subset of HD-audio codes. You can find the current code in topic/hda-core branch. In this branch, the bus and HD-audio codec core are moved into sound/hda. You may grasp an image from the main header file include/sound/hdaudio.h. The split and cleanup of controller driver code is in development, and some pieces are found in sound-unstable git tree as of now. The patches will be submitted once when all settled down. Meanwhile, there is another patchset I've set previously for the regmap support. This is found in topic/hda-regmap branch, which is built on top of topic/hda-core branch. Unless any serious problem is found, I'm going to merge this as well. Note that this needs some fixes in regmap side, so this branch might be rebased in future to merge the regmap fixes into it. One undecided thing is whether we keep codes in sound/pci/hda directory, or move everything into sound/hda, e.g. sound/hda/legacy/pci/hda_intel.c, sound/hda/legacy/codecs/*.c. The obvious drawback of moving files is that it makes backport difficult, so it's bad for stable kernels. As of now, I'm inclined to keep them as is now, but I'm open about this. Let me know if you have any suggestions. thanks, Takashi

[alsa-devel] [PATCH V8 0/5] ASoC: QCOM: Add support for ipq806x SOC
by Kenneth Westfield 16 Mar '15

16 Mar '15

From: Kenneth Westfield <kwestfie(a)codeaurora.org> This patch series adds support for I2S audio playback on the Storm board, which contains a Qualcomm Technologies ipq806x SOC and a Maxim max98357a DAC/amp. The ipq806x SOC has audio-related hardware blocks in its low-power audio subsystem (or LPASS). One of the relevant blocks in the LPASS is its low-power audio interface (or LPAIF). This contains an MI2S port, which is what these drivers are configured to use. The LPAIF also contains a DMA engine that is dedicated to moving audio samples into the transmit FIFO of the MI2S port. One bus from the MI2S port of the SOC is connected to the DAC/amp for stereo playback. This bus is configured so that the SOC is bus master and consists of DATA, LRCLK, and BCLK. The DAC/amp does not need MCLK to operate. In addition, a single GPIO pin from the SOC is connected to the same DAC/amp, which gives enable/disable control over the DAC/amp. The specific drivers added are: * a codec DAI driver for controlling the DAC/amp (applied from V4) * a CPU DAI driver for controlling the MI2S port (applied from V7) * a platform driver for controlling the LPAIF DMA engine (applied from V7) * a machine driver that instantiates a dai-link for playback The LPASS also contains clocks that need to be controlled. Those drivers have been submitted as several separate patch series: * [PATCH v3 0/8] qcom audio clock control drivers http://lkml.org/lkml/2015/1/19/656 * [PATCH] arm: dts: qcom: Add LCC nodes https://lkml.org/lkml/2015/1/28/557 * [PATCH 1/2] arm: qcom_defconfig: Enable lpass clock driver https://lkml.org/lkml/2015/1/28/582 * [PATCH] clk: qcom: Fix ipq806x LCC frequency tables https://lkml.org/lkml/2015/2/26/774 * [PATCH v2] clk: qcom: Properly change rates for ahbix clock https://lkml.org/lkml/2015/3/6/878 Even though the ipq806x LPASS does not contain an audio DSP, other SOCs do have one. For those SOCs, the audio DSP typically controls the hardware blocks in the LPASS. Hence, different CPU DAI driver(s) would need to be used in order to facilitate audio with the DSP. As such, the LPASS DT binding description alludes to an optional adsp phandle, which is not present for this SOC. For other SOCs that do contain an audio DSP, the phandle should exist and refer to a an adsp node. Not using the audio DSP on an SOC that does have one would require different CPU DAI driver(s), in addition to possible bootloader and/or firmware changes. Note that the use of a phandle was a modification that has been submitted as part of a separate patch series. Corresponding additions to the device tree for the ipq806x SOC and its documentation have also been added.

[alsa-devel] [PATCH] ALSA: hda - Don't access stereo amps for mono channel widgets
by Takashi Iwai 16 Mar '15

16 Mar '15

The current HDA generic parser initializes / modifies the amp values always in stereo, but this seems causing the problem on ALC3229 codec that has a few mono channel widgets: namely, these mono widgets react to actions for both channels equally. In the driver code, we do care the mono channel and create a control only for the left channel (as defined in HD-audio spec) for such a node. When the control is updated, only the left channel value is changed. However, in the resume, the right channel value is also restored from the initial value we took as stereo, and this overwrites the left channel value. This ends up being the silent output as the right channel has been never touched and remains muted. This patch covers the places where unconditional stereo amp accesses are done and converts to the conditional accesses.

16 Mar '15

Hi Mark These are DPCM based sampling rate convert support patch-set for Rensas sound driver. Then, it doesn't use simple-card. it uses new Renesas specific sound card driver, but it is copied from simple-card. Current ASoC DPCM needs route settings for FE/BE, but sometimes it will have trouble, because many drivers are using same name for this routing. This patch set solved this issue too. 1 - 2 : prepare patch for Renesas new sound card driver 3 - 4 : DAPM routing issue solution patches 5 - 6 : new Renesas sound card driver 7 - 11 : fixup/tidyup patches for rsnd 12 - 13 : DPCM support patch for rsnd Kuninori Morimoto (13): 1) ASoC: core: remove of_xlate_dai_name from snd_soc_component_driver 2) ASoC: core: add snd_soc_get_dai_info() to get driver infomation 3) ASoC: dapm: add snd_soc_dapm_route_scan macro for DAPM route 4) ASoC: dapm: add driver prefix matching for snd_soc_dapm_add_route() 5) ASoC: rsnd-dpcm-card: add Renesas sound card support for DPCM 6) ASoC: rsnd-dpcm-card: add .be_hw_params_fixup support for convert rate 7) ASoC: rsnd: no more SSI restart when unusual situation 8) ASoC: rsnd: no more SRC restart when unusual situation 9) ASoC: rsnd: tidyup error message format 10) ASoC: rsnd: show debug info for sampling rate convert 11) ASoC: rsnd: don't call clk_prepare_enable/unprepare() from inside spin lock 12) ASoC: rsnd: add dai_link stream name 13) ASoC: rsnd: add DPCM based sampling rate convert Documentation/devicetree/bindings/sound/renesas,rsnd-dpcm-card.txt | 72 ++++++++++++++ include/sound/soc.h | 6 +- sound/soc/sh/Kconfig | 5 + sound/soc/sh/rcar/Makefile | 5 +- sound/soc/sh/rcar/adg.c | 2 + sound/soc/sh/rcar/core.c | 48 ++++++++- sound/soc/sh/rcar/dvc.c | 12 +-- sound/soc/sh/rcar/rsnd-dpcm-card.c | 491 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ sound/soc/sh/rcar/rsnd.h | 16 ++- sound/soc/sh/rcar/src.c | 63 ++++++++++-- sound/soc/sh/rcar/ssi.c | 31 ++++-- sound/soc/soc-core.c | 71 ++++++++------ sound/soc/soc-dapm.c | 33 +++++-- 13 files changed, 780 insertions(+), 75 deletions(-) Best regards --- Kuninori Morimoto

[alsa-devel] Issues and/or possible bugs in alsa
by Yomi Ogunwumi 15 Mar '15

15 Mar '15

Hello. I seem to have run into a few issues with alsa. First, when I plug my headphones into my laptop, sound continues to play out of the speakers and doesn't switch over to (or unmute) the headphones. Auto-Mute Mode is enabled in alsamixer. The same thing happens when I unplug the headphones, it doesn't switch over to the speakers. I have to do the same thing I described above, (no unmuting, I just have to turn up the volume for the speakers in alsamixer.) Second. When I plug in these headphones, I can't use the internal microphone on this laptop, it mutes. (AFAICT) These headphones do not have a microphone built in, they're just an ordinary pair of headphones. However, I was given a workaround in #alsa on freenode. In order to use the laptop's internal microphone with my headphones plugged in, I have to do : sudo hda-verb /dev/snd/hwC1D0 0x22 SET_CONNECT_SEL 6 — it works, but it isn't really ideal. alsa-info is here : https://gist.github.com/Yomi0/9bfc3e72588cf8a35811 The first file in that gist is alsa-info with headphones and the second is without headphones. Third. This is just a question. Is this : https://bugs.freedesktop.org/show_bug.cgi?id=86676 actually a pulseaudio bug, or is it an issue with alsa? I'm only asking since Raymond linked something that seemed to belong to the alsa project. Thank you. -- *Yomi*

[alsa-devel] [PATCH] ASoC: fsl-ssi: Fix bitclock calculation for master mode
by Marc Kleine-Budde 15 Mar '15

15 Mar '15

From: Sascha Hauer <s.hauer(a)pengutronix.de> in fsl_ssi_set_bclk we are looking for the best divider by iterating over all possible dividers. The divider is in the range 1..256, so make this clear by using 'div' as name for the loop counter and iterate from 1 to 256 instead of 0 to 255. This makes obvious that tmprate is calculated wrong, it has to be freq * factor * div, not freq * factor * (i + 2).

This bitmap must be interpreted as a two-dimensional bit array that has a row for each logical input channel and a column for each logical output channel. If a bit at position [u, v] is set, this means that the Mixer Unit contains a programmable mixing Control that connects input channel u to output channel v. If bit [u, v] is clear, this indicates that the connection between input channel u and output channel v is non-programmable. Its fixed value can be retrieved through the appropriate request. The valid range for u is from one to n. The valid range for v is from one to m. The bmControls field stores the bit array row after row where the MSb of the first byte corresponds to the connection between input channel 1 and output channel 1. If (n x m) is not an integer multiple of 8, the bit array is padded with zeros until an integer number of bytes is occupied. The number of bytes used to store the bit array, N, can be calculated as follows: IF ((n x m) MOD 8) <> 0 THEN N = ((n x m) DIV 8) + 1 ELSE N = ((n x m) DIV 8) Index of a string descriptor, describing the name of the first logical channel. >> > iChannelNames 0 Index of a string descriptor, describing the Mixer Unit. >> >> > iMixer 33 >> >> >> if (check_matrix_bitmap(c, ich, och, num_outs)) { >> ich_has_controls = 1; >> break; >> } >> } This mean value returned by check_matrix_bitmap() is incorrect as >> >> > bmControls 0x00 >> >> > bmControls 0x00 >> if (ich_has_controls) >> build_mixer_unit_ctl(state, desc, pin, ich, >> unitid, &iterm); >> } >> } >> return 0; >> } > >

[alsa-devel] [PATCH RFC (do not merge)] ASoC: davinci-mcasp: Set rule constraint if implicit bclk divider is used
by Jyri Sarha 13 Mar '15

13 Mar '15

Set a rule constraint to allow only sample-rate and sample-format combinations that can be played/captured with reasonable accuracy. Signed-off-by: Jyri Sarha <jsarha(a)ti.com> --- In theory this patch does exactly what it is supposed to. It only allows a sample-rate and sample-format combination if the rate can be produced with reasonable accuracy. Unfortunately the alsa-lib and alsa-tools are not able use this information too well. If the requested sample-rate and sample-format is not available the aplay/arecord fails, even if plughw is selected, with: pcm_params.c:170: snd1_pcm_hw_param_get_min: Assertion `!snd_interval_empty(i)' failed.

[alsa-devel] Adding new (old) SNDRV_SEQ_PORT_TYPE_MIDI_* defines
by Adam Goode 13 Mar '15

13 Mar '15

Hi, I found the /* TODO: read port flags from descriptors */ in sound/usb/midi.c and was thinking about what to do to implement this. The first thing to do would be to ensure that all the flags from the element descriptors in the USB MIDI standard are available for returning from snd_seq_port_info_get_type. USB MIDI (see page 23): http://www.usb.org/developers/docs/devclass_docs/midi10.pdf I propose adding these flags to ALSA: #define SNDRV_SEQ_PORT_TYPE_MIDI_CLOCK (1<<7) /* MIDI CLOCK compatible device */ #define SNDRV_SEQ_PORT_TYPE_MIDI_TIME_CODE (1<<8) /* MTC compatible device */ #define SNDRV_SEQ_PORT_TYPE_MIDI_MACHINE_CONTROL (1<<9) /* MMC compatible device */ #define SNDRV_SEQ_PORT_TYPE_MIDI_EFX (1<<21) /* Audio effects processor device */ #define SNDRV_SEQ_PORT_TYPE_MIDI_PATCH_BAY (1<<22) /* MIDI patcher or router device */ #define SNDRV_SEQ_PORT_TYPE_MIDI_DLS1 (1<<23) /* DownLoadable Sounds Standard Level 1 compatible device */ #define SNDRV_SEQ_PORT_TYPE_MIDI_DLS2 (1<<24) /* DownLoadable Sounds Standard Level 2 compatible device */ Thoughts? I can send a couple patches for the kernel and alsa-lib. I don't think this is a breaking change. Thanks, Adam

[alsa-devel] struct timespec as part of kernel/userspace ABI
by Tim Cussins 13 Mar '15

13 Mar '15

Hi all, Like the other ALSA ioctls, the proposed start_at ioctl currently uses struct timespec. A reviewer (of the start_at patchset) has mentioned that communicating timespecs across the kernel/userspace boundary requires special 32bit/64bit compatibility handling (pcm_compat.c). I didn't appreciate this :( Should I follow the same pcm_compat.c pattern for dealing with timespecs for the proposed start_at ioctl? Cheers, Tim

[alsa-devel] [PATCH] ASoC: Intel: Add suspend_pre and resume_post for Braswell snd_soc_card
by Jin Yao 13 Mar '15

On Braswell, we need to add some machine specific setting before suspend and after resume. For example, disable/enable jack detection in codec so use snd_soc_card suspend_pre and resume_post ops for this purpose.

[alsa-devel] [PATCH v2] ALSA: control: Add sanity checks for user ctl id name string

There was no check about the id string of user control elements, so we accepted even a control element with an empty string, which is obviously bogus.

In the commit [2225e79b9b03: 'ALSA: core: reduce stack usage related to snd_ctl_new()'], the id field of the newly added kctl is untouched, thus all attribute like name string remain empty.

[alsa-devel] Microphone Not Working after Suspend on Apple MacBookAir5, 2 Cirrus Logic CS4206
by Vasil Zlatanov 12 Mar '15

12 Mar '15

Issue as seen on reddit thread: https://www.reddit.com/r/linux/comments/1kccbk/alsa_bug_driving_me_crazy_pl… A common problem for Apple Macbook Air 5.2 users where microphone does not work after system resume. As users have noted microphone starts working ones again when the volume is changed in alsa-mixer. alsa-info dumps are attached showing before and after being adjusted (where before causes microphone not to work while in after it does) IRC user 'debianuser' kindly helped out and found that using the two following commands fix the issue: amixer -cPCH set "Capture" 0% nocap amixer -cPCH set "Capture" 100% cap In my experience both are required and they seem to have the same effect as manually changing the volume level in alsamixer, and as such resolve the issue (until another suspend when they have to be run again). As of now I'm resolving this issue by creating a service that is to run after resume from susspend with the given amixer commands to renable the microphone. The second issue, which is also in the reddit thread, is that the microphine is mono and when recording only right channel audio is seen. For me this broke programs such as mumble and skype. A alsa-info output with coefficients is attached. 'debianuser' managed to find a solution to this issue well, resolving it by running the following two commands: hda-verb /dev/snd/hwC0D0 0x11 SET_COEF_INDEX 2 hda-verb /dev/snd/hwC0D0 0x11 SET_PROC_COEF 0x102a After one runs them a single time after boot, the channels collectly show and programs issues are resolved. 'debianuser' mentions that the sources for the commands are available in the kernel and applied to the macbook 8.1 model, but not to mine.

[alsa-devel] [PATCH] ASoC: wm8994: Manage wm8994's MCLK in codec driver
by Inha Song 12 Mar '15

12 Mar '15

Previously, When we use wm8994 codec, we should control its MCLK in machine driver. But, It should be managed by wm8994 codec driver, not machine driver. This patch add MCLK clock DT parsing logic and control own MCLK.

[alsa-devel] ti, codec property in sound/soc/omap/omap-twl4030.c not used
by Belisko Marek 12 Mar '15

12 Mar '15

Hi, I'm looking at sources for omap-twl4030.c driver which is used by many boards. In DT bindings documentation is property ti,codec described as mandatory but it's never parsed in driver code. I did small experiment in gta04 board and remove ti,codec from devicetree and sound was working. I think it can be removed from documentation and also from various device trees. Is my assumption correct? Thanks.

[alsa-devel] [PATCH] ALSA: snd-usb: add quirks for Roland UA-22
by Daniel Mack 12 Mar '15

[alsa-devel] [PATCH] rate: Allow LGPL for libsamplerate commercial licensee

alsa-plugins-rate is tagged with GPL just for following the license of libsamplerate. However, libsamplerate provides a commercial license to allow it used with less restrictions.

[alsa-devel] [PATCH 0/8] Fix struct clk pointer comparing
by Shawn Guo 12 Mar '15

12 Mar '15

On the first day back from Chinese new year holiday, I got a regression report from rmk, saying Ethernet stops working on HimmingBoard with v4.0-rc1. I read through the thread [1] and found a couple of i.MX audio drivers are also affected per Stephen's Coccinelle report. That's why I came up with this series based on Quentin's structclk.cocci, Stephen's result and Mike's input (thanks all). The first two patches are run-time tested and all others are compile-tested only.

[alsa-devel] [PATCH] ALSA: hda - Fix built-in mic on Compaq Presario CQ60
by Takashi Iwai 11 Mar '15

11 Mar '15

Compaq Presario CQ60 laptop with CX20561 gives a wrong pin for the built-in mic NID 0x17 instead of NID 0x1d, and it results in the non-working mic. This patch just remaps the pin correctly via fixup.

[alsa-devel] [PATCH v2 1/2] ASoC: rt5670: Add IRQ function
by Bard Liao 11 Mar '15

11 Mar '15

This patch adds the IRQ function support of rt5670. We use a flag named dev_gpio in platform data to inform codec driver if the IRQ function is used or not. Also, we export rt5670_set_jack_detect for machine driver to pass the jack point.

[alsa-devel] [PATCH] ASoC: Intel: move the jack creation to Braswell machine driver
by Jin Yao 11 Mar '15

11 Mar '15

The jack creation code was in rt5670 codec driver before due to the jack resources (gpio/irq) were defined under the node of codec device in ACPI on Braswell. We used the snd_soc_jack_new() to create a jack instance. But now snd_soc_jack_new() is removed from upstream and we can't use snd_soc_card_jack_new() in codec driver, so we move the jack creation code to machine driver and pass the jack instance to codec driver for further processing.

[alsa-devel] [PATCH] SoC: rt5670: Add IRQ function
by Bard Liao 11 Mar '15

11 Mar '15

This patch adds the IRQ function support of rt5670. We use a flag named dev_gpio in platform data to inform codec driver if the IRQ function is used or not. Also, we export rt5670_set_jack_detect for machine driver to pass the jack point.

[alsa-devel] [PATCH 1/2] ASoC: rt5670: Add IRQ function
by Bard Liao 11 Mar '15

11 Mar '15

This patch adds the IRQ function support of rt5670. We use a flag named dev_gpio in platform data to inform codec driver if the IRQ function is used or not. Also, we export rt5670_set_jack_detect for machine driver to pass the jack point.

[alsa-devel] [PATCH 00/14] Fix wrong ctl value references in ASoC codecs
by Takashi Iwai 10 Mar '15

10 Mar '15

Hi, while looking through the ASoC codec codes, I noticed that lots of drivers refer to the wrong union value type for boolean controls. They should be value.integer.value[], but the code accesses to value.enumerated.item[]. They haven't been noticed so far maybe just because both are same on 32bit architectures. But they are incompatible on 64bit architectures, thus must be fixed.

[alsa-devel] [PATCH] ALSA: firewire-lib: leave unit reference counting completely

10 Mar '15

With previous commit, this module managed to leave the counting to each drivers, but the isochronous resources functionality still increment/decrement the count.

[alsa-devel] [PATCH] ALSA: dice: fix wrong offsets for Dice interface
by Takashi Sakamoto 10 Mar '15

10 Mar '15

For received packet stream, the offset of 'RX_SEQ_START' locates after the offset of 'RX_NUMBER_MIDI', although current macro and proc output includes wrong offsets. Fortunately, this bug doesn't affect streaming functionality because these macro is not used. This commit fixes these wrong macro and outputs.

[alsa-devel] About iMX6SL sign extension of SSI Receive Configuration Register (SSIx_SRCR)
by Xuebing Wang 10 Mar '15

10 Mar '15

Hi Nicolin and community, iMX6SL reference manual section "48.9.8 SSI Receive Configuration Register (SSIx_SRCR)" says about sign extension. Below is a quote from iMX6SL reference manual: ------------------------------------------------------------- Receive Data Extension. This control bit allows SSI to store the received data word in sign extended form. This bit affects data storage only in case received data is LSB aligned (SRCR[9]=1) 0 OFF — Sign extension turned off. 1 ON — Sign extension turned on. ------------------------------------------------------------- After I receive data (in the format of S16_LE) from SSI/I2S, I got data like 0x7FFF or 0x77d2. Are they supposed to be 0xFFFF or 0xF7d2? After setting bit 10 (RXEXT) of SSIx_SRCR, I still get 0x7FFF or 0x77d2. -- Note: SRCR[9] is 1. Any suggestions? Thanks. -- Xuebing

[alsa-devel] [DAPM question] DAPM support for single input multiple outputs
by Qiao Zhou 10 Mar '15

10 Mar '15

Hi Mark, I have one question and need your suggestion. Thanks in advance. In our DSP, one stream path is like this: There is one bit controlling whether a signal A goes to A_out or B_out. That's the reverse case of DAPM_MUX(multiple inputs, single output). One way is to use two switches but it seems not good since two switches control the same bit. It's strange. Do you have any opinion about such requirement support? -- Best Regards Qiao

[alsa-devel] [PATCH] ASoC: tlv320aic23: remove incorrect __exit markups
by Dmitry Torokhov 09 Mar '15

09 Mar '15

Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.

[alsa-devel] [PATCH 2/2] ASoC: wm8996: ensure lower bounds of 1 for timeout
by Nicholas Mc Guire 09 Mar '15

09 Mar '15

wait_for_completion_timeout can be called with timeout == 0 due to msecs_to_jiffies(2) == 1 for HZ < 1000 and usecs_to_jiffies(300) == 1 for all reasonable values of HZ, thus the following timeout /= 2; sets timeout to 0. This patch simply adds a lower-bounds of 1. Signed-off-by: Nicholas Mc Guire <hofrat(a)osadl.org> --- line numbers from wm9666.c linux-next -next-20150306 2101 /* Wait for the FLL to lock, using the interrupt if possible */ 2102 if (Fref > 1000000) 2103 timeout = usecs_to_jiffies(300); 2104 else 2105 timeout = msecs_to_jiffies(2); 2106 2107 /* Allow substantially longer if we've actually got the IRQ, poll 2108 * at a slightly higher rate if we don't. 2109 */ 2110 if (i2c->irq) 2111 timeout *= 10; 2112 else 2113 timeout /= 2; 2114 2115 ret = wait_for_completion_timeout(&wm8996->fll_lock, 2116 timeout); The call-path here would then be: wait_for_completion_timeout(...,timeout) -> wait_for_common action==schedule_timeout -> schedule_timeout(timeout) ... expire = timeout + jiffies; so expire == jiffies here and the timer would expire immediately for systems with HZ<1000 due to msecs_to_jiffies(2) == 1 and the following timeout /= 2 -> timeout == 0, which is probably a bit more that a "slightly higher rate".

Re: [alsa-devel] Using loopback card to Connect GSM two way call to the real sound card UDA1345TS
by Srinivasan S 09 Mar '15

09 Mar '15

Dear All, Could you please provide any inputs w.r.t the loopback card using snd-aloop & alsaloop, how this loopback card can be used to connect the GSM two way call simultanoeusly to the UDA1345TS codec on MCASP0 of the am335x (UDA1345TS ie., real sound card) The codec has two output channels VOUTL, VOUTR & two input channels VINL , VINR As I am pretty new to linux audio particularly ALSA Framework as I was involved only in intial codec bringup using aplay & arecord utilities , as I was having some trouble getting a grasp on it all, (as I want this to be darecord one in ALSA only without entering into gstreamer or ffmpeg, could you please confirm on the same that whether can it be done in ALSA only) If this probably isn't the place to ask this question, but I am not sure where is. Feel free to point me somewhere else if there is a better place :) So it seems what is happening is basically when i up the channels from VINL to VOUTL, & VINR to VOUTR ie., I am able capture from VINR & play back using VOUTR & similarly I am able to capture from VINR & route to VOUTR using the below asound.conf & the attached application With this am able to achieve only one way call at a time by running only one application at a time ie., alsa_loopback_min_mono_VINL.c or alsa_loopback_min_mono_VINR.c Could you please kindly let me know how two way call can be established simultaneously finally with only one application , as I tried merging both apps ie., (alsa_loopback_min_mono_VINL & alsa_loopback_min_mono_VINR) at that moment am getting device resource busy, when I tried to open snd_pcm_open (&playback_handle_left, pldevice, SND_PCM_STREAM_PLAYBACK, 0) in the application alsa_loopback_min_mono.c Kindly do the needful as early as possible, Awaiting for your replies, Many Many Thanks a lot for your replies & would appreciate the same w.r.t my earlier two queries

[alsa-devel] [PATCH v2 0/3] Improve eye-diagram & single-ended test for rk3288 hdmi
by Yakir Yang 09 Mar '15

09 Mar '15

RK3288 hdmi eye-diagram test would fail when pixel clock is 148.5MHz, and single-ended test would failed when display mode is 74.25MHz. To fix such problems, we make those patch set: - Fix some code style, leave space for next patches. - For hdmi eye-diagram test, we turn on the Transmitter Trailer-B and improve slopeboost to 10%-20% decrease. - For hdmi single-ended test, we set CKLVL to 18 and & TXLVL to 19 when pixel clock is 74.25MHz, keep CKLVL & TXLVL to 13 when pixel clock is 148.5MHz. Changes in v2: - set slopeboost back to 10%-20%, then rasing/falling time would pass. - For pixel clock less than 74.25MHz, set txlvl to 19 and set cklvl to 18.

[alsa-devel] [PATCH] ASoC: Fix component lists locking
by Lars-Peter Clausen 08 Mar '15

08 Mar '15

Any access to the component_list, codec_list and platform_list needs to be properly locked by the client_mutex. Otherwise undefined behavior can occur if the list is modified in one thread and concurrently accessed from another thread. This patch adds the missing locking to the debugfs file handlers that display the registered components, as well as the various components unregister functions. Furthermore the client_lock is now held for the whole snd_soc_instantiate_card() sequence to make sure that component removal does not race against the card registration.

[alsa-devel] [PATCH] ALSA: hda - Fix regression of HD-audio controller fallback modes
by Takashi Iwai 08 Mar '15

08 Mar '15

The commit [63e51fd708f5: ALSA: hda - Don't take unresponsive D3 transition too serious] introduced a conditional fallback behavior to the HD-audio controller depending on the flag set. However, it introduced a silly bug, too, that the flag was evaluated in a reverse way. This resulted in a regression of HD-audio controller driver where it can't go to the fallback mode at communication errors. Unfortunately (or fortunately?) this didn't come up until recently because the affected code path is an error handling that happens only on an unstable hardware chip. Most of recent chips work stably, thus they didn't hit this problem. Now, we've got a regression report with a VIA chip, and this seems indeed requiring the fallback to the polling mode, and finally the bug was revealed. The fix is a oneliner to remove the wrong logical NOT in the check. (Lesson learned - be careful about double negation.) The bug should be backported to stable, but the patch won't be applicable to 3.13 or earlier because of the code splits. The stable fix patches for earlier kernels will be posted later manually.

[alsa-devel] [RFC 0/5] Create hdalib for common hda code
by Vinod Koul 08 Mar '15

08 Mar '15

This patch series attempts to split existing HDA code to create common hda library. This is done in order to make HDA code available to other users like upcoming Intel platforms which sport a HDA controller along with an I2S link. This series is 1st patch series which will try to refactor HDA by splitting it up and then adding ASoC HDA controller driver for these platforms. This series moves code to sound/hda, renames the files mostly. The second series will do API changes and subsequent ones will be using HDA bus patches which Takashi posted recently Comments welcome... ~Vinod Jeeja KP (5): ALSA: hda: move hdaudio header files to global include ALSA: HDA: create HDA common lib ALSA: hdalib - fix existing checkpatch issues ALSA: hda: rename sound/hda/hda* as sound/hda/hdalib ALSA: hdalib: rename common header files as hdalib_* .../hda/hda_priv.h => include/sound/hda_register.h | 10 +-- .../sound/hdalib_auto_parser.h | 6 +- .../hda/hda_beep.h => include/sound/hdalib_beep.h | 6 +- .../hda_codec.h => include/sound/hdalib_codec.h | 23 +++--- .../sound/hdalib_controller.h | 11 +-- .../hda_local.h => include/sound/hdalib_controls.h | 20 ++--- .../sound/hdalib_generic.h | 6 +- include/sound/{hda_hwdep.h => hdalib_hwdep.h} | 4 +- .../hda/hda_jack.h => include/sound/hdalib_jack.h | 6 +- sound/Kconfig | 2 + sound/Makefile | 2 +- sound/hda/Kconfig | 85 ++++++++++++++++++++ sound/hda/Makefile | 21 +++++ sound/{pci => }/hda/hda_intel_trace.h | 0 sound/{pci => }/hda/hda_trace.h | 0 .../hda_auto_parser.c => hda/hdalib_auto_parser.c} | 7 +- sound/{pci/hda/hda_beep.c => hda/hdalib_beep.c} | 8 +- sound/{pci/hda/hda_codec.c => hda/hdalib_codec.c} | 21 +++-- .../hda_controller.c => hda/hdalib_controller.c} | 10 ++- sound/{pci/hda/hda_eld.c => hda/hdalib_eld.c} | 4 +- .../hda/hda_generic.c => hda/hdalib_generic.c} | 13 +-- sound/{pci/hda/hda_hwdep.c => hda/hdalib_hwdep.c} | 6 +- sound/{pci/hda/hda_jack.c => hda/hdalib_jack.c} | 8 +- sound/{pci/hda/hda_proc.c => hda/hdalib_proc.c} | 13 +-- sound/{pci/hda/hda_sysfs.c => hda/hdalib_sysfs.c} | 6 +- sound/pci/hda/Kconfig | 44 ---------- sound/pci/hda/Makefile | 14 +--- sound/pci/hda/hda_i915.c | 3 +- sound/pci/hda/hda_intel.c | 7 +- sound/pci/hda/patch_hdmi.c | 10 ++- sound/pci/hda/patch_realtek.c | 10 ++- 31 files changed, 229 insertions(+), 157 deletions(-) rename sound/pci/hda/hda_priv.h => include/sound/hda_register.h (98%) rename sound/pci/hda/hda_auto_parser.h => include/sound/hdalib_auto_parser.h (96%) rename sound/pci/hda/hda_beep.h => include/sound/hdalib_beep.h (95%) rename sound/pci/hda/hda_codec.h => include/sound/hdalib_codec.h (97%) rename sound/pci/hda/hda_controller.h => include/sound/hdalib_controller.h (90%) rename sound/pci/hda/hda_local.h => include/sound/hdalib_controls.h (98%) rename sound/pci/hda/hda_generic.h => include/sound/hdalib_generic.h (99%) rename include/sound/{hda_hwdep.h => hdalib_hwdep.h} (95%) rename sound/pci/hda/hda_jack.h => include/sound/hdalib_jack.h (96%) create mode 100644 sound/hda/Kconfig create mode 100644 sound/hda/Makefile rename sound/{pci => }/hda/hda_intel_trace.h (100%) rename sound/{pci => }/hda/hda_trace.h (100%) rename sound/{pci/hda/hda_auto_parser.c => hda/hdalib_auto_parser.c} (99%) rename sound/{pci/hda/hda_beep.c => hda/hdalib_beep.c} (98%) rename sound/{pci/hda/hda_codec.c => hda/hdalib_codec.c} (99%) rename sound/{pci/hda/hda_controller.c => hda/hdalib_controller.c} (99%) rename sound/{pci/hda/hda_eld.c => hda/hdalib_eld.c} (99%) rename sound/{pci/hda/hda_generic.c => hda/hdalib_generic.c} (99%) rename sound/{pci/hda/hda_hwdep.c => hda/hdalib_hwdep.c} (96%) rename sound/{pci/hda/hda_jack.c => hda/hdalib_jack.c} (99%) rename sound/{pci/hda/hda_proc.c => hda/hdalib_proc.c} (99%) rename sound/{pci/hda/hda_sysfs.c => hda/hdalib_sysfs.c} (99%) -- 1.7.9.5

[alsa-devel] [PATCH 1/2] snd-waveartist: Introduce Rockwell WaveArtist RWA010 driver
by Ondrej Zary 08 Mar '15

08 Mar '15

This is a new ALSA driver driver for Rockwell WaveArtist RWA010 chips found on some (rare) ISA sound cards, such as DCS Multimedia S717. I wasn't able to get the old OSS WaveArtist driver to work with my card but it was a great source of information about the chip (as the full datasheet is not available - only a brief one and a design guide). However, the OSS driver only supports few of the mixer registers so I had to install the card in Windows and dump mixer registers while changing the mixer settings. Then tried what the rest of the registers do and the result is a fully working mixer which even supports more controls than the Windows driver. Someone with a NetWinder can add support for it to this driver and then remove the old OSS one.

[alsa-devel] KBN-1 HD-audio
by Russ Whitaker 08 Mar '15

08 Mar '15

Hi A little over a year age I got a ECS KBN-1 which has on-board HD-audio chip: card0, card1. Determined I needed to make card1 the default and someone was kind enough to send me a simple one line "fix." So simplein fact, I didn't write it down. Now I'm installing new software on a new partition and I need that fix again, please. This time I promise to write it down in my ECS user manual. Thanks, Russ

[alsa-devel] [Patch V7 00/10] ASoC: QCOM: Add support for ipq806x SOC
by Kenneth Westfield 07 Mar '15

07 Mar '15

From: Kenneth Westfield <kwestfie(a)codeaurora.org> This patch series adds support for I2S audio playback on the Storm board, which contains a Qualcomm Technologies ipq806x SOC and a Maxim max98357a DAC/amp. The ipq806x SOC has audio-related hardware blocks in its low-power audio subsystem (or LPASS). One of the relevant blocks in the LPASS is its low-power audio interface (or LPAIF). This contains an MI2S port, which is what these drivers are configured to use. The LPAIF also contains a DMA engine that is dedicated to moving audio samples into the transmit FIFO of the MI2S port. One bus from the MI2S port of the SOC is connected to the DAC/amp for stereo playback. This bus is configured so that the SOC is bus master and consists of DATA, LRCLK, and BCLK. The DAC/amp does not need MCLK to operate. In addition, a single GPIO pin from the SOC is connected to the same DAC/amp, which gives enable/disable control over the DAC/amp. The specific drivers added are: * a CPU DAI driver for controlling the MI2S port * a platform driver for controlling the LPAIF DMA engine * a machine driver that instantiates a dai-link for playback The LPASS also contains clocks that need to be controlled. Those drivers have been submitted as several separate patch series: * [PATCH v3 0/8] qcom audio clock control drivers http://lkml.org/lkml/2015/1/19/656 * [PATCH] clk: qcom: Properly change rates for ahbix clock https://lkml.org/lkml/2015/2/25/706 * [PATCH] clk: qcom: Fix ipq806x LCC frequency tables https://lkml.org/lkml/2015/2/26/774 Even though the ipq806x LPASS does not contain an audio DSP, other SOCs do have one. For those SOCs, the audio DSP typically controls the hardware blocks in the LPASS. Hence, different CPU DAI driver(s) would need to be used in order to facilitate audio with the DSP. As such, the LPASS DT contains an adsp subnode, which is disabled for this SOC. The same subnode should be enabled and populated for other SOCs that do contain an audio DSP. Not using the audio DSP would require different CPU DAI driver(s), in addition to possible bootloader and/or firmware changes. Corresponding additions to the device tree for the ipq806x SOC and its documentation has also been added. Also, as this is a new directory, the MAINTAINERS file has been updated as well. = Changes since V6 [Patch V6 00/10] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2015-February/088218.h… * Added REGMAP_MMIO selection for the CPU and platform drivers * Modified the AHBIX frequency to match the corresponding LCC fix * Tweaked the logging in the CPU driver probe. = Changes since V5 [Patch V5 00/12] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2015-February/087832.h… * Correctly use Storm as the build target label and DT binding label. * Added audio DSP sub-node to the LPASS device tree, disabled for this SOC. * Added logic to CPU DAI driver to fail the probe() if a DSP is present. * Use the standard naming convention for the DAI link properties. * General code cleanup. = Changes since V4 [Patch V4 00/10] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2015-February/087499.h… * Replaced simple-card with a machine driver to resolve the system clock configuration, rather than having the CPU DAI driver do it. * Added header files to avoid indirect header dependencies and implicit forward declarations. * Tweaked the ISR to match the conventions of the surrounding code. * Removed the usage of the low-power memory as it is not needed. * Removed the use of the DRV_NAME constant. * Added explicit dependency on gpiolib for the codec driver. * Moved the MODULE_DEVICE_TABLE macro inside the CONFIG_OF conditional. * Modified the documentation to reflect the changes. * General code cleanup. = Changes since V3 [Patch V3 00/10] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2014-December/085694.h… * Placed the content of the inline functions into the callbacks. * Replaced use of readl/writel register access functions with regmap access functions. Notable exception is the ISR, which uses ioread32/iowrite32. * Rearranged the sequencing of the hardware block enables to fit within the ASoC framework callbacks, while remaining functional. REQ 1: The hardware requires the enable sequence to be: LPAIF-DMA[enable],then LPAIF-MI2S[enable], then DAC-GPIO[enable] REQ 2: The hardware requires the disable sequence to be: DAC-GPIO[disable], then LPAIF-MI2S[disable] * Corrected the implementation of the pointer callback. * Utilize the LPM to buffer audio samples, rather than memory external to LPASS. * Corrected the interrupt clearing in the ISR. * Implemented a default system clock (defined by the simple-card DT node), and optional LPASS DT node modifiers that can alter the system clock in order to expand the range of available bit clock frequencies. * Addressed all of the remaining issues raised by Mark Brown. * General code cleanup. = Changes since V2 [Patch v2 00/11] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2014-December/085186.h… * Removed the PCM platform driver from the DTS platform and tied it to the CPU DAI driver. * Changed I2S pinctrl to use generic naming convention and moved control to CPU DAI driver. It should be controlled now by soc-core's pinctrl_pm_* functionality. * Added stub DAPM support in codec driver. As the DAC GPIO needs to be enabled last when starting playback, and disabled first when stopping playback, it seems as though the trigger function may be the place for this. Suggestions are welcome for a better place to put this. * Removed machine driver and tied DAI drivers to simple-audio-card. * Packaged the build files and Maxim codec files together in one change. * Removed QCOM as vendor from Maxim code and documentation. * Separated the SOC and board definitions into the correct DTS files. * Update device tree documentation to reflect changes. * General code cleanup. = Changes since V1 [PATCH 0/9] ASoC: QCOM: Add support for ipq806x SOC http://mailman.alsa-project.org/pipermail/alsa-devel/2014-November/084322.h… * Remove the native LPAIF driver, and move its functionality to the CPU DAI driver. * Add a codec driver to manage the pins going to the external DAC (previously managed by the machine driver). * Use devm_* and dev_* where possible. * ISR only handles relevant DMA channel now. * Update device tree documentation to reflect changes. * General code cleanup.

A DSP expects only one scratch, but hsw_parse_fw_image() allocates scratch blocks for each firmware image it parses. Move the allocate function sst_block_alloc_scratch() out of hsw_parse_fw_image() to make sure a scratch be allocated only after all firmware images be parsed.

Phone should always try to fill the uplink, no? (Or do you detect silence and not transmit in this case?) (Actually, I guess applications should be ready for "data not ready" case even on "normal" hardware due to differing clocks.) Packets vs. stream of samples... does userland need to know about the packets? Could we simply hide it from the userland? As userland daemon is (supposed to be) realtime, do we really need extra set of timestamps? What other metadata are there? Uplink timing... As the daemon is realtime, can it just send the data at the right time? Also normally uplink would be filled, no? > Some definite similarities: > - the mmap interface to manage the PCM buffers (that is on purpose > similar to that of ALSA) > > The interface was designed so that the audio mixer (e.g. Pulseaudio) is run > with a soft real-time SCHED_FIFO/RR user-space thread that has full control > over _when_ voice _packets_ are sent, and can receive packets with meta-data > (see libcmtspeechdata interface, cmtspeech.h), and can detect and handle > gaps in the received packets. Well, packets are of fixed size, right? So the userland can simply supply the right size in the common case. As for sending at the right time... well... if the userspace is already real-time, that should be easy. Now, there's a difference in the downlink. Maybe ALSA people have an idea what to do in this case? Perhaps we can just provide artificial "zero" data? > This is very different from modems that offer an actual PCM voice link for > example over I2S to the application processor (there are lots of these on > the market).
