[alsa-devel] [PATCH v3 0/2] Add support for select accessory detect mode to HPDETL or HPDETR
by Inha Song 27 Apr '15

27 Apr '15

This set of patches adds support for select accessory detect mode to HPDETL or HPDETR. Changes in v3: - Set the hpdet_channel default value to HPDETL If the value is unknown or invalid. Changes in v2: - Use the value in pdata instead of hpdet_channel in extcon_info. - Wrap arizona_extcon_of_get in IS_ENABLED(CONFIG_OF). - Change hpdet_channel type to unsigned from signed in pdata. - Move ARIZONA_ACCDET_MODE_* define to dt-binding header and directly set it to pdata.

[alsa-devel] [RFC] dice: simplifying address registration
by Takashi Sakamoto 25 Apr '15

25 Apr '15

Clemens, Would I request your comments about an attached patch? Currently Dice driver keeps address ranges for each unit instance. But there's a way to reuse the same address range. I think this idea can simplify driver probe processing and save resources of host controller. Regards Takashi Sakamoto

The manual says: http://www.prismsound.com/music_recording/products_subs/orpheus/online_manu… (Contents -> Orpheus hardware -> Stand-alone operation): --------------------------------- Stand-alone operation --------------------------------- It is possible to operate Orpheus without a FireWire connection to a host computer. This is done by setting up the unit as required using the Orpheus Control Panel applet whilst it is connected to a host computer via its FireWire interface, then placing the unit in standby by pressing the standby button, before disconnecting the unit from the host and power source. When the unit is re-powered, and detects that no FireWire connection is active, <========== I missed this part! it reloads the settings which were previously stored. As Takashi Sakamoto mentioned: > Currently, libffado has a bug to fail to switch clock > source for usual BeBoB driver. > So we have no way to set the source of clock correctly. > I've tried to fix it but get stuck deeply into > ffado's fault and given up. this could be a problem for me, too. Anyway, the functionality I expect snd-bebob to have is no more than what is offered by juju+libffado+jack. Mike Ood

[alsa-devel] [RFC v2] ASoC: Topology File format
by Liam Girdwood 24 Apr '15

24 Apr '15

Here's V2 of the file format the userspace topology tool will read to generate the binary output file. The output file uses the topology UAPI structures to represent the objects in the text file. This is still WiP and is based on the UCM file format from Jaroslav. Changes from V1. o Added BE's and Codec <-> codec links o Added enumerated and binary controls o Added private data o Moved object names from name field into object top level (like section names). o Control ops binding changed to string+number #

[alsa-devel] [PATCH 0/8] Proc file cleanups
by Takashi Iwai 23 Apr '15

23 Apr '15

Hi, here is a series of patches for cleaning up the ALSA proc file management code. The biggest change is the use of seq_file for text reads, but all are internal and the API is kept intact. The rest are mostly small cleanups and refactoring. The patches are found in topic/proc branch of sound git tree. Takashi === Takashi Iwai (8): ALSA: core: Use seq_file for text proc file reads ALSA: core: Fix possible memory leaks at error path in info.c ALSA: core: Remove child proc file elements recursively ALSA: core: Manage asound root directory with snd_info_entry ALSA: core: Remove superfluous exit calls for proc entries ALSA: core: Don't ignore errors at creating proc files ALSA: core: Build conditionally and remove superfluous ifdefs ALSA: core: Clean up OSS proc file management include/sound/core.h | 4 - include/sound/info.h | 29 +- sound/core/Makefile | 8 +- sound/core/info.c | 779 ++++++++++++++++++---------------------------- sound/core/info_oss.c | 29 +- sound/core/init.c | 33 +- sound/core/seq/Makefile | 3 +- sound/core/seq/seq_info.c | 19 +- sound/core/sound.c | 24 +- sound/core/sound_oss.c | 30 +- 10 files changed, 373 insertions(+), 585 deletions(-) -- 2.3.5

[alsa-devel] [RFC] File format for topology data
by Liam Girdwood 23 Apr '15

23 Apr '15

I've pasted below the topology data for the broadwell firmware using the text file format being used by UCM. Using the UCM format allows to to share parser code and allows us to also have UCM define topology data. I've not yet completed the byte or enum controls but the rest of the data is there for comments. I've also included the recent channel changes suggested in the UAPI header comments. # Firmware Topology Configuration for Broadwell # TLV scale used by both global and stream volumes SectionTLV."hsw_vol_tlv" { DBScale [ min "-9000" step "300" mute "1" ] } # Controls from default pipeline SectionControl."Default Pipeline" { Index "1" # Master DSP volume Mixer [ name "Master Playback Volume" Channel.0 [ map "Left" reg "0" shift "0" ] Channel.1 [ map "Right" reg "0" shift "8" ] max "31" invert "false" get "0" put "0" tlv_array "hsw_vol_tlv" ] # Offload 0 volume Mixer [ name "Media0 Playback Volume" Channel.0 [ map "Left" reg "1" shift "0" ] Channel.1 [ map "Right" reg "1" shift "8" ] max "31" invert "false" get "1" put "1" tlv_array "hsw_vol_tlv" ] # Enum controls Enum [ ... ] # Byte controls Bytes [ ... ] } # DAPM Widgets for main pipeline SectionWidget."Pipeline1" { Index "1" AIF_IN [ name "SSP0 CODEC IN" stream_name "" slot "" reg "0" shift "0" invert "false" ] AIF_OUT [ name "SSP0 CODEC OUT" stream_name "" slot "" reg "0" shift "0" invert "false" ] ... } # DAPM Routes SectionGraph."Pipeline 1 Graph" { Index 1 Routes [ "Playback VMixer, , System Playback" "Playback VMixer, , Offload0 Playback" "Playback VMixer, , Offload1 Playback" "SSP0 CODEC OUT, , Playback VMixer" "Analog Capture, , SSP0 CODEC IN" ] } # PCM Configurations supported by FW SectionPCMConfig."PCM 48k Stereo 24bit" { Playback [ format "S24_LE" rate "48000" channels "2" tdm_slot "0xf" ] Capture [ format "S24_LE" rate "48000" channels "2" tdm_slot "0xf" ] } SectionPCMConfig."PCM 48k Stereo 16bit" { Playback [ format "S16_LE" rate "48000" channels "2" tdm_slot "0xf" ] Capture [ format "S16_LE" rate "48000" channels "2" tdm_slot "0xf" ] } SectionPCMConfig."PCM 48k 2P/4C 16bit" { Playback [ format "S16_LE" rate "48000" channels "2" tdm_slot "0xf" ] Capture [ format "S16_LE" rate "48000" channels "4" tdm_slot "0xf" ] } # PCM capabilities supported by FW SectionPCMCapabilities."System Playback" { Capabilities [ formats "S24_LE, S16_LE" rate_min "48000" rate_max "48000" channels_min "2" channels_max "2" ] } SectionPCMCapabilities."Analog Capture" { Capabilities [ formats "S24_LE, S16_LE" rate_min "48000" rate_max "48000" channels_min "2" channels_max "4" ] } SectionPCMCapabilities."Offload Pin Playback" { Capabilities [ formats "S24_LE, S16_LE" rate_min "8000" rate_max "192000" channels_min "2" channels_max "2" ] } SectionPCMCapabilities."Loopback Capture" { Capabilities [ formats "S16_LE" rate_min "48000" rate_max "48000" channels_min "2" channels_max "2" ] } # PCM devices exported by Firmware SectionPCM."System Pin" { Index 1 Playback [ Capabilities "System Playback" Config "PCM 48k Stereo 24bit" Config "PCM 48k Stereo 16bit" ] Capture [ Capabilities "Analog Capture" Config "PCM 48k Stereo 24bit" Config "PCM 48k Stereo 16bit" Config "PCM 48k 2P/4C 16bit" ] } SectionPCM."Offload Pin 0" { Index 1 Playback [ Capabilities "Offload Pin Playback" Config "PCM 48k Stereo 24bit" Config "PCM 48k Stereo 16bit" ] } SectionPCM."Offload Pin 1" { Index 1 Playback [ Capabilities "Offload Pin Playback" Config "PCM 48k Stereo 24bit" Config "PCM 48k Stereo 16bit" ] } SectionPCM."Loopback Pin" { Index 1 Capture [ Capabilities "Loopback Capture" Config "PCM 48k Stereo 16bit" ] }

[alsa-devel] [PATCH] ALSA: hda - add AZX_DCAPS_I915_POWERWELL to Baytrail
by mengdong.lin＠intel.com 23 Apr '15

23 Apr '15

From: Mengdong Lin <mengdong.lin(a)intel.com> This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail). Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared power well with GPU. This power well must be turned on before we reset link to probe the codec, to avoid communication failure with the codec. The side effect is that this power is always ON in S0 because the BYT HDMI codec does not support EPSS or D3ClkStop and so the controller doesn't enter D3 at runtime, and the HDMI codec and analog codec share a single physical HD-A link and so we cannot reset the HD-A link freely when we re-enable the power to use the HDMI codec. Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is okay to bring the HDMI codec back to a functional state after restoring the power. If okay, we can bind the power on/off with the HDMI codec PM without interrupting the analog audio.

[alsa-devel] [RFC] bind/unbind SoC devices with deferred list
by Kuninori Morimoto 23 Apr '15

23 Apr '15

Hi Takashi, Mark, Lars I worked for bind/unbind issue which was discussed before http://thread.gmane.org/gmane.linux.alsa.devel/134062/focus=134076 http://thread.gmane.org/gmane.linux.alsa.devel/134283/focus=134287 I would like to know your opinion before sending patch to Greg The problem is ASoC has card/platform/cpu/codec relationship for each other, but, we can unbind one of them, and then, other related devices doesn't know about it. Thus, kernel will error if we use sound after that. Here is example of this issue. It unbind cpu (= rcar_sound), playback sound, and, error. And, we can't re-bind after this. // check current sound card > aplay -l **** List of PLAYBACK Hardware Devices **** card 0: rsnddai0ak4642h [rsnd-dai.0-ak4642-hifi], device 0: rsnd-dai.0-ak4642-hifi ak4642-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 // unbind cpu (= rcar_sound) > echo ec500000.rcar_sound > /sys/bus/platform/drivers/rcar_sound/unbind // recheck sound card // card doesn't know cpu was removed > aplay -l **** List of PLAYBACK Hardware Devices **** card 0: rsnddai0ak4642h [rsnd-dai.0-ak4642-hifi], device 0: rsnd-dai.0-ak4642-hifi ak4642-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 // kernel error happen if playback > aplay xxx.wav Unable to handle kernel NULL pointer dereference at virtual address 00000100 pgd = ee97c000 ... // we can't re-bind cpu > echo ec500000.rcar_sound > /sys/bus/platform/drivers/rcar_sound/bind -- freeze -- I hacked this issue to using deferred list, and created attached patch. it is all-in-one patch. but it solved my issue.

[alsa-devel] [PATCH v8 0/7] ALSA: jack: Refactoring for jack kctls
by Jie Yang 22 Apr '15

22 Apr '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 new implementation, both HDA and soc jack kctls works fine, they are compatible for old HDA jack kctls, too. For soc, a. snd_jack_new() with NULL jack_kctl; b. for each pin, call snd_jack_add_kctls() to add one kctl(it will call snd_ctl_add() to add kctl to card); For HDA, With snd_jack_new(), we can use phantom_jack = true for phantom jack creating, and the jack kctl pointer will be filled with the new created kcontrol. Changes in v8: 1. remove snd_jack_kctl from HDA part, change snd_jack_new param to use bool for creating kcontrol at jack creating stage; 2. create jack for phantom jack, with no input device; 3. remove HDA jack get_unique_index() and index related code. Changes in v7: 1. move name generating and index getting part into ctljack.c; 2. remove exposing private_data and destructor to hda, then jack core can handle kctls by itself totally. 3. some small code fixing. Changes in v6: 1. refine kctl name generating function; 2. integrate HDA jack kctl more deeply, support phantom jack in snd_jack_new(); 3. add documentation for Jack kcontrols to explain how to use it. Changes in v5: 1. remove SND_KCTL_JACK config item, we need jack kctl once CONFIG_SND_JACK is selected. Changes in v4: 1. use snd_ctl_find_id() to get avaliable index; 2. add initial kctl for snd_jack_new(compatible for HDA); 3. add struct snd_jack_kctl * field to struct hda_jack_tbl; 4. new kctls for soc jack during jack pins creating. 5. add a patch to remove exporting snd_kctl_jack_new(). 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. *** BLURB HERE *** Jie Yang (7): ALSA: jack: implement kctl creating for jack device ALSA: Jack: refactoring snd_kctl_jack_new to support embedded kctl ALSA: jack: extend snd_jack_new to support phantom jack ALSA: hda - Update to use the new jack kctls method ASoC: jack: create kctls according to jack pins info ALSA: jack: remove exporting ctljack functions ALSA: Docs: Add documentation for Jack kcontrols Documentation/sound/alsa/Jack-Controls.txt | 48 ++++++++++ include/sound/control.h | 2 +- include/sound/jack.h | 19 +++- sound/core/Kconfig | 3 - sound/core/Makefile | 3 +- sound/core/ctljack.c | 41 +++++++-- sound/core/jack.c | 142 ++++++++++++++++++++++++++--- sound/pci/hda/Kconfig | 1 - sound/pci/hda/hda_jack.c | 90 +++++------------- sound/pci/hda/hda_jack.h | 5 +- sound/pci/hda/patch_hdmi.c | 2 +- sound/pci/oxygen/xonar_wm87x6.c | 2 +- sound/soc/soc-jack.c | 3 +- 13 files changed, 260 insertions(+), 101 deletions(-) create mode 100644 Documentation/sound/alsa/Jack-Controls.txt -- 1.9.1

[alsa-devel] [RFC 1/4] ASoC: topology: Add topology UAPI header.
by Liam Girdwood 22 Apr '15

22 Apr '15

The ASoC topology UAPI header defines the structures required to define any DSP firmware audio topology and control objects from userspace. The following objects are supported :- o kcontrols including TLV controls. o DAPM widgets and graph elements o Vendor bespoke objects. o Coefficient data o FE PCM capabilities and config. o BE link capabilities and config. o Codec <-> codec link capabilities and config. o Topology object manifest. The file format is simple and divided into blocks for each object type and each block has a header that defines it's size and type. Blocks can be in any order of type and can either all be in a single file or spread across more than one file. Blocks also have a group identifier ID so that they can be loaded and unloaded by ID.

[alsa-devel] [PATCH 0/2] Calculate BCLK using TDM slots and remove channels rule
by Jyri Sarha 22 Apr '15

22 Apr '15

The first patch is a bugfix. I did not have the HW see the problem myself, but reading from the code the problem is evident. This should also fix Dan Carpenter's concern about stack usage in davinci_mcasp_hw_rule_channels(), as the whole function is removed. The second patch is just an optimization of the sample-rate rule. In effect I put in use Takashi Iwai's suggestion for fixing the stack usage issue in the channels rule.

[alsa-devel] [PATCH v7 0/7] ALSA: jack: Refactoring for jack kctls
by Jie Yang 22 Apr '15

22 Apr '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 new implementation, both HDA and soc jack kctls works fine, they are compatible for old HDA jack kctls, too. For soc, a. snd_jack_new() with NULL jack_kctl; b. for each pin, call snd_jack_add_kctls() to add one kctl(it will call snd_ctl_add() to add kctl to card); For HDA, With snd_jack_new(), we can use phantom_jack = true for phantom jack creating, and the jack kctl pointer will be filled with the new created kcontrol. Changes in v7: 1. move name generating and index getting part into ctljack.c; 2. remove exposing private_data and destructor to hda, then jack core can handle kctls by itself totally. 3. some small code fixing. Changes in v6: 1. refine kctl name generating function; 2. integrate HDA jack kctl more deeply, support phantom jack in snd_jack_new(); 3. add documentation for Jack kcontrols to explain how to use it. Changes in v5: 1. remove SND_KCTL_JACK config item, we need jack kctl once CONFIG_SND_JACK is selected. Changes in v4: 1. use snd_ctl_find_id() to get avaliable index; 2. add initial kctl for snd_jack_new(compatible for HDA); 3. add struct snd_jack_kctl * field to struct hda_jack_tbl; 4. new kctls for soc jack during jack pins creating. 5. add a patch to remove exporting snd_kctl_jack_new(). 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] [RFC 0/4] ASoC DSP topology
by Liam Girdwood 22 Apr '15

22 Apr '15

It's been about 2 years since posting V1 of the ASoC dynamic firmware patches and a lot has changed since then ... This RFC series is being posted instead of a V2 patch series atm since we are still completing some testing on the codebase and developing a new userspace tool. Expect V2 once more testing is completed shortly. ASoC topology (formerly called dynamic firmware) allows audio DSP topology to be defined as part of the firmware package and not hard coded into the driver. This allows DSP vendors to ship multiple different firmwares or firmwares with programmable topologies for different devices (i.e. phones, tablets, TVs) using a single DSP driver. The DSP topology can be contained as part of the firmware file or exist as separate files. The topology core and file format is generic and not tied to any single vendor or device. The topology core consists of kernel and userspace components :- Kernel. The kernel core reads in the topology data and builds the driver capabilities and audio topology based on this data. This includes building the DAPM graph, setting PCM and DAI capabilities, registering kcontrols and registering DAPM widgets. The userspace tool allows the creation of binary DSP FW topology files based on a topology text files. Changes since V1:- o Name changed to ASoC Topology o Structures from soc.h and soc-dapm.h no longer exposed as UAPIs o Moved to component model from codec/platform model. o Added reserved fields in each UAPI structure. o UAPI structures packed and endianess defined for each structure. o Added support for PCM, DAI and codec <-> codec link capabilities. o Added support for client drivers manifests. o Added support for private data for each dynamic object type. o Single list of dynamic objects rather than list of each object type.

[alsa-devel] [PATCH 1/1] usb-audio: Fix audio output on Roland SC-D70 sound module
by Takamichi Horikawa 21 Apr '15

21 Apr '15

Roland SC-D70 reports its device class as vendor specific class and the quirk QUIRK_AUDIO_FIXED_ENDPOINT was used for audio output. In the quirks table the sampling rate was hard-coded to 44100 Hz and therefore not worked when the sound module was in 48000 Hz mode. In this change the quirk is changed to QUIRK_AUDIO_STANDARD_INTERFACE but as the sound module reports incorrect bSubframeSize in its descriptors, additional change is made in format.c to detect it and to override it (which uses the existing code for Edirol SD-90). Tested both when the sound module was in 44100 Hz mode and 48000 Hz mode and both audio input and output. MIDI related part of the driver is not touched.

[alsa-devel] [PATCH] ALSA: hda - only sync BCLK to the display clock for Haswell & Broadwell
by mengdong.lin＠intel.com 21 Apr '15

21 Apr '15

From: Mengdong Lin <mengdong.lin(a)intel.com> Only Intel Haswell and Broadwell have a separate HD-A controller (PCI device 3) for display audio, which needs to get 24MHz HD-A link BCLK from the variable display core clock through vendor specific registers EM4 & EM5. Other platforms (Baytrail, Braswell and Skylake) don't have this feature. So a new driver quirk AZX_DCAPS_I915_SYNC_CLK is defined for the HSW/BDW display HD-A controller, to sync clock after the shared display power is restored.

[alsa-devel] [PATCH v6 0/6] ALSA: jack: Refactoring for jack kctls
by Jie Yang 21 Apr '15

21 Apr '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 new implementation, both HDA and soc jack kctls works fine, they are compatible for old HDA jack kctls, too. For soc, a. snd_jack_new() with NULL jack_kctl; b. for each pin, call snd_jack_add_kctls() to add one kctl(it will call snd_ctl_add() to add kctl to card); For HDA, With snd_jack_new(), we can use phantom_jack = true for phantom jack creating, and the jack kctl pointer will be filled with the new created kcontrol. Changes in v6: 1. refine kctl name generating function; 2. integrate HDA jack kctl more deeply, support phantom jack in snd_jack_new(); 3. add documentation for Jack kcontrols to explain how to use it. Changes in v5: 1. remove SND_KCTL_JACK config item, we need jack kctl once CONFIG_SND_JACK is selected. Changes in v4: 1. use snd_ctl_find_id() to get avaliable index; 2. add initial kctl for snd_jack_new(compatible for HDA); 3. add struct snd_jack_kctl * field to struct hda_jack_tbl; 4. new kctls for soc jack during jack pins creating. 5. add a patch to remove exporting snd_kctl_jack_new(). 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] ALSA: hda - Mute headphone pin on suspend on XPS13 9333
by Gabriele Mazzotta 20 Apr '15

20 Apr '15

Muting the headphone output pin right before the codec suspension prevents pop noises when headphones are plugged in (except for a barely audible click noise).

[alsa-devel] [PATCH 00/13] ADSP Firmware Controls Update
by Charles Keepax 20 Apr '15

20 Apr '15

This series of patches starts with a few small clean ups for the ADSP code, and then finally adds support for the rev 1 and 2 firmware file formats. The revision 1 format is in common usage in the field so it is long overdue to get support for that merged to mainline. The revision 2 format is fairly new but is starting to see some deployment as well. There is still more work todo here. The main next step is to add support for arbitary length controls through the TLV binary control feature that was recently added to the kernel. This patch series will truncate any long controls to 512 bytes.

[alsa-devel] How to correct params_format on DPCM ?
by Kuninori Morimoto 20 Apr '15

20 Apr '15

Hi Mark, Lars, all Now, I'm using DPCM based sound, but FE/BE gets different params format. How to correct it ? This sound can be used both non-DPCM card / DPCM card -- non-DPCM card -- cpu: rsnd codec: ak4642 -- DPCM card -- FE : cpu: rsnd codec: snd-soc-dummy BE : cpu: snd-soc-dummy codec: ak4642 Here, SNDRV_PCM_FMTBIT_S16_LE is always selected on non-DPCM card. This is OK. rsnd: SNDRV_PCM_FMTBIT_S24_LE | SNDRV_PCM_FMTBIT_S16_LE ak4642: SNDRV_PCM_FMTBIT_S16_LE On DPCM card, FE gets S24, BE gets S16 if aplay selects S24 wav. But, FE needs S16, same as non-DPCM card. I know we can fixup BE side via dai_link.be_hw_params_fixup, but this is FE side. It can't use correct sound playback in corrent DPCM card. But, how to solve this issue ?? Best regards --- Kuninori Morimoto

[alsa-devel] [PATCH] ASoC: at91sam9g20ek: Automatically disconnect non-connected pins
by Lars-Peter Clausen 18 Apr '15

According to the schematics the both LHPOUT and RHPOUT are connected to the external connector. RHPOUT is missing from the DAPM routes, but otherwise they seem to be complete. This patch adds the missing route and then sets the fully_routed flag for the card. This allows to remove all the manual calls to snd_soc_dapm_nc_pin().

[alsa-devel] Understanding Atmel SSC SND_SOC_DAIFMT_CBS_CFS mode
by Angelo Compagnucci 18 Apr '15

18 Apr '15

Hi List, I'm looking for a way to understand how to correctly configure the Atmel SSC dai on a SAMA5D3 to work in master mode with an I2S codec. >From this comment: /* * I2S format, SSC provides BCLK and LRC clocks. * * The SSC transmit and receive clocks are generated * from the MCK divider, and the BCLK signal * is output on the SSC TK line. */ My question is: should be MCK divider configured manually? If yes how? Actually I'm trying to poke around in atmel_ssc_dai and found a way to generate a stable bit clock, but frame clock is not working as expected. Have you any advice on how to set correctly SSC parameters to generate a stable bit clock and frame clock? Any advice? Thank you! -- Profile: http://it.linkedin.com/in/compagnucciangelo

[alsa-devel] Support for Synchronous Audio
by Anoop Rajan 18 Apr '15

18 Apr '15

Hi All, My self Anoop, an audio frame work developer, but a newbie to linux ALSA. We have requirements to play synchronous multi-room audio with very minimal node to node latency(<100 us).( Node to node latency: How much one speaker is out of sync with other). Right now we have logic in user space to synchronize the audio using time stamps derived from a common clock, but the node to node latency is over 1ms. Though I make sure that I start the PCM from user layer synchronously, the actual I2S out is out of sync(in consistent values ranging from 100 to 1ms). I beleive the un-deterministic path delay from user to ALSA buffer, big ALSA buffer(8k Samples), scheduling variances(high priority/interrupt preemption) all might have added to this increased latency. Rather than fine tuning the above discrepancies , I was thinking about some designs to pass the audio frames with time stamps to kernel layer and to implement some logic in kernel (before pushing to DMA) to present the audio at exact stamped time to have a better node to node latency. Before doing that I was trying to find out what ALSA supports for this requirement and from web could see various comments regarding this (proposal to snd_pcm_start_at()<http://mailman.alsa-project.org/pipermail/alsa-devel/2014-October/082091.ht…>) and further proposed discussions on Audio mini summit, but I couldn't find further information's on it. Would you please guide me. Does ALSA provides some means to achieve minimal Node to Node latency? would you please provide some pointers/documents to me to understand better. Thanks, Anoop

[alsa-devel] [PATCH] sound/oss: fix deadlock in sequencer_ioctl(SNDCTL_SEQ_OUTOFBAND)
by Alexey Khoroshilov 18 Apr '15

18 Apr '15

A deadlock can be initiated by userspace via ioctl(SNDCTL_SEQ_OUTOFBAND) on /dev/sequencer with TMR_ECHO midi event. In this case the control flow is: sound_ioctl() -> case SND_DEV_SEQ: case SND_DEV_SEQ2: sequencer_ioctl() -> case SNDCTL_SEQ_OUTOFBAND: spin_lock_irqsave(&lock,flags); play_event(); -> case EV_TIMING: seq_timing_event() -> case TMR_ECHO: seq_copy_to_input() -> spin_lock_irqsave(&lock,flags); It seems that spin_lock_irqsave() around play_event() is not necessary, because the only other call location in seq_startplay() makes the call without acquiring spinlock. So, the patch just removes spinlocks around play_event(). By the way, it removes unreachable code in seq_timing_event(), since (seq_mode == SEQ_2) case is handled in the beginning. Compile tested only. Found by Linux Driver Verification project (linuxtesting.org).

[alsa-devel] [RFC 2/4] ASoC: topology: Add topology core
by Liam Girdwood 16 Apr '15

16 Apr '15

The topology core parses the FW topology file for known block types and instanciates any common ALSA/ASoC objects that it discovers. The core also passes any block that is does not understand to client component drivers for enumeration. The core exports some APIs to client drivers in order to load and unload firmware topology data as use case require. Currently the core deals with the following object types :- o kcontrols. This includes TLV, enumerated and bytes controls. o DAPM widgets. All types with any associated kcontrol. o DAPM graph. o FE PCM. FE PCM capabilities and configuration can be defined. o BE DAI Link. BE DAI link capabilities and configuration can be defined. o Codec <-> codec style links capabilities and configuration.

[alsa-devel] [PATCH 00/16] HD-audio core controller split
by Takashi Iwai 16 Apr '15

16 Apr '15

Hi, this is a patch series for splitting the existing HD-audio controller code to a core library. The purose of this split is to help writing other HD-audio controller codes more easily. With these library codes, a controller driver can be written up with small skeleton codes. I have done quick tests, and no obvious regression found, so submitted here for reviews. The patches are found in topic/hda branch of sound git tree. Note that this series isn't targeted for 4.1 but for 4.2.

[alsa-devel] [PATCH 0/2] i2c: rework last users of 2.4 style attach_adapter
by Wolfram Sang 16 Apr '15

16 Apr '15

The attach_adapter mechanism of the I2C framework is deprecated for years. There are two users left; drivers for old Macintosh computers. I got the idea of replacing this mechanism with a custom one with the help of deferred probing. Because I don't have the hardware, I modified the windtunnel driver to be runnable on my Renesas Lager board (ARM). This patch is not in this series but in the branch mentioned below. I first verified that the attach_adapter method was in deed used for bus scanning. When scanning, the driver rightfully failed on detecting the actual i2c clients because there is no such hardware on my board. However, the actual scanning happened. Using my custom mechanism, the same happens: all busses get scanned, then the clients cannot be detected. Since I didn't change the actual detection code, I assume that it should be working on those Macintosh devices as well. The keywest driver is only compile-tested. That being said, I'd be more than happy, if we could find someone willing to test these patches. Top-of-tree kernel would be nice, but these patches can easily be backported to probably the beginning of deferred probing. I will also notify some ppc lists of distributions of this thread for further help. If this works out, we can _finally_ get rid of this stone-age mechanism and clean up the i2c core. Changes since RFC: return -ENODEV instead of 0 when exiting the while loop (= nothing found on all busses) The branch I used for ARM compilation is here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/attach_adapter_removal_with_arm_compile-experimental Thanks, Wolfram Wolfram Sang (2): macintosh: therm_windtunnel: drop using attach adapter sound: ppc: keywest: drop using attach adapter drivers/macintosh/therm_windtunnel.c | 25 +++++++++++++++++++++++-- sound/ppc/keywest.c | 23 +++++++++++++++++++---- 2 files changed, 42 insertions(+), 6 deletions(-) -- 2.1.4

[alsa-devel] Separate input and output jacks for one UCM device?
by Tanu Kaskinen 16 Apr '15

16 Apr '15

Hi Liam and alsa-devel, My understanding is that a UCM device can represent a thing that has both input and output (I don't particularly like that, but it's too late to complain). How likely do you think that there are or there will be some drivers that expose separate input and output jack kcontrols for a headset jack, to differentiate between headphones/headset/microphone? My understanding is that jack kcontrols store only booleans, so there's no way to distinguish between headphones and a headset with just one kcontrol. The current UCM "spec" doesn't support specifying multiple kcontrols, since there's only one "JackControl" value. (Perhaps the "JackDev" value suffers from this problem too, but I don't know if jack input devices already support reporting the state separately for input and output.) -- Tanu

[alsa-devel] [PATCH] ASoC: rsnd: set dmaen->chan = NULL when error case
by Kuninori Morimoto 15 Apr '15

15 Apr '15

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> rsnd_dmaen_quit() is assuming dmaen->chan is NULL if it failed to get DMAEngine channel. but, current dmaen->chan might have error value when error case (this driver is checking it by IS_ERR_OR_NULL()) This patch makes sure dmaen->chan is NULL when error case. Otherwise, it will contact to unknown address in rsnd_dmaen_quit() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> --- sound/soc/sh/rcar/dma.c | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/soc/sh/rcar/dma.c b/sound/soc/sh/rcar/dma.c index ac3756f..144308f 100644 --- a/sound/soc/sh/rcar/dma.c +++ b/sound/soc/sh/rcar/dma.c @@ -156,6 +156,7 @@ static int rsnd_dmaen_init(struct rsnd_priv *priv, struct rsnd_dma *dma, int id, (void *)id); } if (IS_ERR_OR_NULL(dmaen->chan)) { + dmaen->chan = NULL; dev_err(dev, "can't get dma channel\n"); goto rsnd_dma_channel_err; } -- 1.9.1

> Of course. Not only does this page say so: > http://www.alsa-project.org/main/index.php/SMP_Design Ah, I read this, but that's probably just if two threads would share one handle: "The use of returned handles must be serialized in the application using own locking scheme." One more question: You said snd_pcm_wait() was real time safe. I guess that's also true for similar functions, like snd_pcm_htimestamp(), snd_pcm_readi(), ..., correct?

[alsa-devel] recording problem in beagleboard-mcbsp
by noman pouigt 15 Apr '15

15 Apr '15

Problem: not able to record with any of the devices in beagleboard-xm. Analysis: userspace is stuck in snd_pcm_readi function and kernel space i don't see snd_pcm_update_hw_ptr function being called. Checked the I2S clocks and they are perfect and recording data line is moving based on the data. I am able to do playback though. I am using below command to do recording. Do i need to add additional switches?

In any case, How I can put silence in buffer to avoid underrun? Do you know the answer? Thank you in advance.

[alsa-devel] alsa-announce list not used anymore?
by Tanu Kaskinen 14 Apr '15

14 Apr '15

Hi, I was thinking of subscribing to alsa-announce, but it seems that there have been no messages sent there in years. Is it ok if I remove the list from the wiki page at http://alsa-project.org/main/index.php/Mailing-lists ? Hmm... it seems that the wiki page has many other obsolete lists too... Is it so that only alsa-user and alsa-devel are relevant nowadays? -- Tanu

You're really 100 percent sure that this is guaranteed to work? Sorry for asking this :) I was expecting a "No, of course not.". Also, this will probably work for all handle-based-functions, as long as you keep using pairwise different handles? Regards, Johannes

[alsa-devel] parallel, real time safe waiting?
by Johannes Lorenz 14 Apr '15

14 Apr '15

Hello, I'd like to write a sequencer that can handle many synthesizers. Thus, I want them to run these synths parallel. Still, I'd like to keep my code real time safe, i.e. no malloc(), usleep(), ofstream, pthread mutexes etc. However, I wondered how to let all my threads sleep for x useconds if there's nothing to do for x useconds. My idea was: 1.) Let each thread open a handle using snd_seq_open() 2.) Call snd_pcm_wait() in each thread Are these functions a) real time safe? b) race-condition free, assuming I'll use pairwise different handles each thread Many thanks for any help. Kind regards, Johannes

[alsa-devel] [PATCH] ALSA: hda - not use regmap for vendor verb 0x781 of Intel HDMI codec
by mengdong.lin＠intel.com 14 Apr '15

14 Apr '15

From: Mengdong Lin <mengdong.lin(a)intel.com> For HDMI codec on Haswell/Broadwell/Skylake platforms, the vendor verb 0x781 is used enable DP 1.2 mode as a fixup if BIOS has not done this, in function intel_haswell_fixup_enable_dp12(). Otherwise, the display audio playback will be silent. Although the verb 0x781 is added to vendor verbs array, but snd_hdac_regmap_ encode_verb() will translate it to verb 0xf81 and cause regmap_write IO failure because 0xf81 is not in the vendor verb array and so will not be taken as a writable register. So this patch no longer uses regmap for verb 0x781 but directly send this command to enable DP1.2 mode.

Re: [alsa-devel] ASoC: davinci-mcasp: Set rule constraints if implicit BCLK divider is used
by Dan Carpenter 13 Apr '15

13 Apr '15

Hello Jyri Sarha, The patch a75a053f1eef: "ASoC: davinci-mcasp: Set rule constraints if implicit BCLK divider is used" from Mar 20, 2015, leads to the following Sparse warning: sound/soc/davinci/davinci-mcasp.c:1098:45: warning: Variable length array is used. sound/soc/davinci/davinci-mcasp.c 1088 static int davinci_mcasp_hw_rule_channels(struct snd_pcm_hw_params *params, 1089 struct snd_pcm_hw_rule *rule) 1090 { 1091 struct davinci_mcasp_ruledata *rd = rule->private; 1092 struct snd_interval *ci = 1093 hw_param_interval(params, SNDRV_PCM_HW_PARAM_CHANNELS); 1094 int sbits = params_width(params); 1095 int rate = params_rate(params); 1096 int max_chan_per_wire = rd->mcasp->tdm_slots < ci->max ? 1097 rd->mcasp->tdm_slots : ci->max; 1098 unsigned int list[ci->max - ci->min + 1]; ^^^^^^^^^^^^^^^^^^^^^ I wasnt able to determine where these values are capped. The worry is that the kernel only has an 8k stack so if they are too high it could oops. I think these values can come from the user in snd_pcm_hw_params_user() but I'm an newbie to the code and I didn't see where the limits were enforced. 1099 int c1, c, count = 0; 1100 1101 for (c1 = ci->min; c1 <= max_chan_per_wire; c1++) { 1102 uint bclk_freq = c1*sbits*rate; 1103 int ppm; regards, dan carpenter

BTW we now have a WARN triggering on BSW due to hda trying to query the current cdclk frequency. https://bugs.freedesktop.org/show_bug.cgi?id=90012 I'm not sure if hda really needs to know the cdclk freq on BSW or not. But in either case I think we should just kill the HAS_DDI check. Once these patches land the code will anyway work on all platforms.

[alsa-devel] [PATCH] ctl: fix to handle several elements added by one operation for userspace element
by Takashi Sakamoto 13 Apr '15

13 Apr '15

An element instance can have several elements with the same feature. Some userspace applications can add such an element instance by add operation with the number of elements. Then, the element instance gets a memory object to keep states of these elements. But the element instance has just one memory object for the elements. This causes the same result to each read/write operations to the different elements. This commit fixes this bug by allocating enough memory objects to the element instance for each of elements.

[alsa-devel] [PATCH 1/2] ASoC: atmel: Add dependency to SND_SOC_I2C_AND_SPI where necessary
by Lars-Peter Clausen 12 Apr '15

12 Apr '15

The SND_AT91_SOC_SAM9G20_WM8731 and SND_AT91_SOC_SAM9X5_WM8731 machine driver symbols select SND_SOC_WM8731 which depends on SND_SOC_I2C_AND_SPI. So the machine driver symbols need to depend on SND_SOC_I2C_AND_SPI as well, otherwise we might end up with a invalid configuration, which will sooner or later upset the randconfig auto-builders.

12 Apr '15

This patchset is for refactoring control core code. The first patch is re-send http://mailman.alsa-project.org/pipermail/alsa-devel/2015-February/087700.h… The second patch is new. As long as I investigated, the changed code was written in 1999 and its basic design have never been changed. In my opinion, the design is a bit complicated and refactoring it is better to decrease maintaining cost.

[alsa-devel] [PATCH v5 0/5] ALSA: jack: Refactoring for jack kctls
by Jie Yang 12 Apr '15

12 Apr '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 new implementation, both HDA and soc jack kctls works fine, they are compatible for old HDA jack kctls, too. For soc, a. snd_jack_new() with NULL jack_kctl; b. for each pin, call snd_jack_add_kctls() to add one kctl(it will call snd_ctl_add() to add kctl to card); For hda, a. call snd_jack_kctl_new()(in __snd_hda_jack_add_kctl()) to new a jack_kctl(also new kctl); and use snd_hda_ctl_add to add kctl to card; b. new a hda_jack_tbl, appoint jack_tbl->jack_kctl = jack_kctl; c. for non-phantom jack, call snd_jack_new() with this jack_kctl, then the jack_kctl will be added to the new created jack; Changes in v5: 1. remove SND_KCTL_JACK config item, we need jack kctl once CONFIG_SND_JACK is selected. Changes in v4: 1. use snd_ctl_find_id() to get avaliable index; 2. add initial kctl for snd_jack_new(compatible for HDA); 3. add struct snd_jack_kctl * field to struct hda_jack_tbl; 4. new kctls for soc jack during jack pins creating. 5. add a patch to remove exporting snd_kctl_jack_new(). 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 0/4] ALSA: ctl: fix userspace control element operations
by Takashi Sakamoto 12 Apr '15

12 Apr '15

This patchset is to fix some issues related to operations for userspace control element. Three patches are related to identical information, the other is related to several element added by one operation. Unfortunately, current alsa-lib has no functionality to achieve the operation to add several element. To demonstrate this and test these patches, I prepare for a small GObject introspection library, alsa-gir. https://github.com/takaswie/alsa-gir This reposiroty includes sample scripts written by python. The file of sample/ctl.py demonstrates userspace control elements. If this library helps your review for this patchset, I'm feeling happy.

[alsa-devel] [PATCH] ASoC: rnsd: fix build regression without CONFIG_OF
by Arnd Bergmann 12 Apr '15

12 Apr '15

The r-car sound driver only works when CONFIG_OF is set, and after a recent change has a compile-time dependency as well: sound/built-in.o: In function `rsnd_dma_request_channel': :(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel' This could be fixed either by adding a static inline wrapper for the function, or by adding a Kconfig dependency. This implements the second approach, which seems appropriate because the driver in fact has a hard dependency.

Sorry for sending this direct at the last minute but due to the GPIO misuse it'd be really good to get it in the release and I'd not realised it hadn't been sent yet - between some travel, a job change and other non-urgent fixes coming in I'd lost track of the urgency.

[alsa-devel] Playback - Overwrite buffer with silence
by Nilhcraiv 11 Apr '15

11 Apr '15

Hello, I am working an application and I have problems playing the audio with ALSA. In my application, I receive the sound data, this data must be decoded to be reproduce. In this process, always obtain an under-runerror. To fix this problem, I followed the documentation i.e. I use snd_pcm_sw_params_set_silence_size() and snd_pcm_sw_params_set_silence_threshold() to overwrite the buffer with silence. --> http://www.alsa-project.org/alsa-doc/alsa-lib/group___p_c_m___s_w___params.… but this does not work. Does the doc is wrong? If I obtain the boundary for ring pointers in frames at the start (snd_pcm_sw_params_get_boundary), the boundary is always zero. If I obtain the boundary each time (in the received_data() function) it is more than the buffer size and I get error when I put it in snd_pcm_sw_params_set_silence_size(), ¿Why?, Is it correct to use the boundary value?, ¿How I can avoid under-run by putting silence if I have not data at time? Here you can see a light version of my code (without error checking): #define FRAMES 240 #define PERIOD 1*FRAMES #define BUFFER_SIZE PERIOD*2 #define CHANNELS 1 #define SAMPLE_RATE 48000 snd_pcm_hw_params_t *hwparams; snd_pcm_sw_params_t *swparams; int exact_rate,dir; snd_pcm_uframes_t boundary=0; snd_pcm_stream_t stream = SND_PCM_STREAM_PLAYBACK; snd_pcm_hw_params_alloca(&hwparams); snd_pcm_sw_params_alloca(&swparams); /*PlayBack hw */ snd_pcm_open(&pcm_handle, "default", stream, 0); snd_pcm_hw_params_any(pcm_handle, hwparams); snd_pcm_hw_params_set_access(pcm_handle, hwparams, SND_PCM_ACCESS_RW_INTERLEAVED); snd_pcm_hw_params_set_format(pcm_handle, hwparams, SND_PCM_FORMAT_S16_LE); exact_rate = SAMPLE_RATE; snd_pcm_hw_params_set_rate_near(pcm_handle, hwparams, &exact_rate, 0); snd_pcm_hw_params_set_channels(pcm_handle, hwparams, CHANNELS); snd_pcm_hw_params_set_buffer_size(pcm_handle, hwparams, BUFFER_SIZE); snd_pcm_hw_params(pcm_handle, hwparams); /*Avoid under-run sw*/ snd_pcm_sw_params_current(pcm_handle, swparams); snd_pcm_sw_params_get_boundary(swparams, &boundary); /*Here, boundary is allways ZERO*/ snd_pcm_sw_params_set_silence_threshold(pcm_handle, swparams, 0); /*According to the doc.*/ snd_pcm_sw_params_set_silence_size(pcm_handle, swparams, boundary); /*According to the doc.*/ snd_pcm_sw_params(pcm_handle,swparams); /*END Avoid under-run*/ snd_pcm_prepare(pcm_handle); void received_data(void *t_data)/*short version of the function*/ { short *decoded_data = NULL; int len=0; decoded_data = (short *)malloc(PERIOD * FRAME_SIZE); len = decoder(&decoded_data,t_data); snd_pcm_sw_params_get_boundary(swparams, &boundary); /*Here, boundary is always a large number*/ snd_pcm_sw_params_set_silence_size(pcm_handle, swparams, boundary);/*Here, boundary in frames is always a large number, and there are an error...*/ snd_pcm_sw_params(pcm_handle,swparams); pcmreturn = snd_pcm_writei(pcm_handle, decoded_data, len);/*In most cases there are UNDERRUN...*/ xrun_recovery(&pcm_handle, pcmreturn);/*Recover in case of an error.*/ } Thanks in advance!

[alsa-devel] [PATCH 0/2] Cygnus Audio Driver
by Scott Branden 11 Apr '15

11 Apr '15

Please provide comments on the initial version of this driver. This patchset contains the devicetree bindings and core audio driver for the Cygnus SoC. There is an open question on how to fit this driver into the clock framework (if at all). The audio PLL is embedded in the audio block and only used by the audio block. The audio PLL registers are also in the middle of the audio register map. In addition, the audio PLL is adjustable to less than 1 Hz. The existing clock driver framework does not provide a mechanism to take advantage of the resolution of the hardware. Can the audio PLL remain within the audio driver and/or any modifications required?

[alsa-devel] [PATCH] ASoC: codecs-ac97: Remove rate constraints
by Maciej S. Szmigiero 10 Apr '15

10 Apr '15

Remove rate constraints from generic ASoC AC'97 CODEC and make it selectable in config. Supported rates should be detected and constrained anyway by AC'97 generic code - was tested with VT1613 CODEC and iMX6 SSI controller. This way this driver can be used for platforms which don't need specialized AC'97 CODEC drivers while at the same avoiding code duplication from implementing equivalent functionality in a controller driver.

[alsa-devel] [PATCH 0/3] ASoC: Intel: IPC/mailbox code refactoring
by Jin Yao 10 Apr '15

10 Apr '15

Hi Mark, Currently in Intel SST driver, some very similar or duplicated IPC/mailbox processing code are used in different platforms. This is a patch series which refactors the common IPC/mailbox code into generic APIs and use the new APIs in Baytrail and Broadwell platforms. This patch series depends on Jie Yang's following patches for build: ASoC: Intel: create atom folder and move atom platform files in ASoC: Intel: create baytrail folder and move baytrail platform files in ASoC: Intel: create boards folder and move sst boards files in ASoC: Intel: create haswell folder and move haswell platform files in ASoC: Intel: create common folder and move common files in Since now Jie Yang's patch series has been applied in intel branch so this patch series will be no build issue.

Try to check whether the reverting the diff of sound/* manually fixes the problem. (i.e. apply diff -R for the diff I showed in the previous mail.) If it doesn't fix but still reverting the whole commit does fix, it means that something else got broken by the merge.

[alsa-devel] [PATCH] ALSA: emu10k1: don't deadlock in proc-functions
by Michael Gernoth 10 Apr '15

10 Apr '15

The functions snd_emu10k1_proc_spdif_read and snd_emu1010_fpga_read acquire the emu_lock before accessing the FPGA. The function used to access the FPGA (snd_emu1010_fpga_read) also tries to take the emu_lock which causes a deadlock. Remove the outer locking in the proc-functions (guarding only the already safe fpga read) to prevent this deadlock.

Hi, The link : https://bugtrack.alsa-project.org/alsa-bug isn't working. After searching in web , I found a discussion which says, that link will be down and we need to send alsa-devel mailing list for any bugs. Is there a different bug tracker being used now or reporting to alsa-devel mailing list is the only way ? Please confirm. Regards, Maruthi

[alsa-devel] [PATCH 0/3] ARM: shmobile: armadillo: fixup CPU settings
by Kuninori Morimoto 10 Apr '15

10 Apr '15

Hi Mark, Lars Cc Simon These patches had been posted in ALSA/SH-ARM ML in http://thread.gmane.org/gmane.linux.ports.sh.devel/43079 by Lars. But, he doesn't have armadillo board, and I commented about FSI driver, and no one update these, these patches were marooned. Original 2/3 patch changed behavior for clock inversion on FSI driver. FSI + wm8978 on armadillo800eva worked without any issues, but, I don't know how much effect it has for other board (many board are using FSI). We used this inversion flags on each board for historical reasons, but, almost all these were not needed (except some picky board) on FSI. Maybe Lars's 2/3 patch is correct, but, it is difficult to check/confirm for all boards. And unfortunately, Renesas don't use FSI anymore. So, I think keeping current FSI driver as-is is more safety for old boards. I tested these patches on latest Mark's branch Lars-Peter Clausen (3): ARM: shmobile: armadillo800eva: Properly specify HDMI audio link format ARM: shmobile: armadillo800eva: fix clock inversion ASoC: simple-card: Remove support for setting differing DAI formats arch/arm/mach-shmobile/board-armadillo800eva.c | 3 +-- include/sound/simple_card.h | 1 - sound/soc/generic/simple-card.c | 30 ++++++++---------------------- 3 files changed, 9 insertions(+), 25 deletions(-)

[alsa-devel] ASoC: Mediatek: Add support for MT8173 SOC
by Koro Chen 10 Apr '15

10 Apr '15

This adds basic support for the Mediatek AFE unit for MT8173 SoC. This patch is based on Linux 4.0-rc1, Sascha's clk patch [1], and his SCPSYS power patch [2]. The AFE unit comprises several memory interfaces that communicate with CPU, a multi input multi output digital audio interconnect, and several external interfaces (e.g. I2S). The AFE unit is a DMA master, so no external DMA engine is needed. Each external interface is presented as a DAI to ASoC. A memory interface must be connected via the interconnect to an external interface. The connection pathes are configured through the device tree.

[alsa-devel] [PATCH 00/14] parport: check success of attach call
by Sudip Mukherjee 10 Apr '15

10 Apr '15

Currently we are not checking if attach has succeeded or not. Also parport_register_driver() always return 0 even if attach fails. But in many places where attach has been used, it can fail. So, modified the parport code to check the return value of attach and accordingly return either 0 or error code from parport_register_driver.

You don't need to reply to every single comment, the general assumption will be that if there's no other followup all review comments will be addressed. It's better to just reply to things where there's something more detailed to say, if you explicitly reply to everything then that makes it easier for actual replies to be missed since there's a lot of there's a lot of the mail that's just going to be skipped through. > >>+static void ringbuf_inc(void __iomem *audio_io, bool is_playback, > >>+ const struct ringbuf_regs *p_rbuf) > >So it looks like we're getting an interrupt per period and we have to > >manually advance to the next one? > Yes. OK, so that seems fragile - what happens if we're slightly late processing an interrupt or miss one entirely? Most hardware has some way to read back the current position which tends to be more reliable, is that not an option here?

Re: [alsa-devel] [PATCH] ASoC: max98090: add shutdown callback for max98090

Can you describe the probelm > better? When device is shutdown with playing music, the origin driver does nothing for shutdown operation, as a result, pmic will cut off the power of codec IC, thus cause a pop noise from speaker and headphone. So the patch added a shutdown callback for driver, enable volume smoothing and disable zero cross, this is referenced from mic_input which does the samething before mic switch.

[alsa-devel] [PATCH] ASoC: rt286: Restore default in probe
by Bard Liao 09 Apr '15

09 Apr '15

[alsa-devel] [patch] ASoC: Intel: do cast earlier in sst_cdev_tstamp()
by Dan Carpenter 09 Apr '15

09 Apr '15

My static checker complains about these because it looks like the multiply can overflow and then we cast to a larger data type. I don't think this is a problem, but it's also harmless to do the cast earlier so let's silence the static checker warning.

The alsa-info.sh outputs show no difference but the power state, so the widget attributes seem kept with the power state change, as it seems.

[alsa-devel] [PATCH] ALSA: hda - Always allow access for POWER_STATE verbs
by Takashi Iwai 09 Apr '15

09 Apr '15

The hdac regmap code checks whether the codec is powered on while accessing, but there must be an exception -- the verbs to control the power state. Currently HD-audio driver doesn't access them via regmap, so this patch doesn't fix any current behavior, but it's just for future.

[alsa-devel] [PATCH 0/5 alsa-lib] amixer fixes for enumerated elements
by Takashi Sakamoto 09 Apr '15

The amixer still has issues according to sset operation to enumerated items. The issues are: - Fail to handle omitted value of each channel. - The name of enumerated element is truncated. - Unclear separators for values of channels. This patchset fixes these issues, including a small code refactoring for better reading. Takashi Sakamoto (5): amixer: gather local variables in the beginning of functions amixer: fix a bug to handle omitted value in parameter for enumerated element amixer: expand local storage for item name according to kernel code amixer: arrange validation logic amixer: use the same characters for separator. amixer/amixer.c | 60 ++++++++++++++++++++++++++++++++++++++++----------------- 1 file changed, 42 insertions(+), 18 deletions(-) -- 2.1.0

[alsa-devel] [PATCH] ALSA: hda - make power_save threshold per-codec
by Matthew Garrett 09 Apr '15

Modern hardware will often have multiple HDA devices, and the desired power saving configuration may vary depending on the codecs attached to each of them. Push the power_save value down to the individual codec structures, keeping the module parameter as a global control mechanism for compatibility purposes.

[alsa-devel] [PATCH 1/4] ASoC: tegra_alc5632: Use card DAPM context to access widgets
by Lars-Peter Clausen 08 Apr '15

08 Apr '15

The dapm field of the snd_soc_codec struct will eventually be removed (replaced with the DAPM context from the component embedded inside the CODEC). Replace its usage with the card's DAPM context. The idea is that DAPM is hierarchical and with the card at the root it is possible to access widgets from other contexts through the card context.

[alsa-devel] [PATCH v4 0/5] ALSA: jack: Refactoring for jack kctls
by Jie Yang 08 Apr '15

08 Apr '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 new implementation, both HDA and soc jack kctls works fine, they are compatible for old HDA jack kctls, too. For soc, a. snd_jack_new() with NULL jack_kctl; b. for each pin, call snd_jack_add_kctls() to add one kctl(it will call snd_ctl_add() to add kctl to card); For hda, a. call snd_jack_kctl_new()(in __snd_hda_jack_add_kctl()) to new a jack_kctl(also new kctl); and use snd_hda_ctl_add to add kctl to card; b. new a hda_jack_tbl, appoint jack_tbl->jack_kctl = jack_kctl; c. for non-phantom jack, call snd_jack_new() with this jack_kctl, then the jack_kctl will be added to the new created jack; Changes in v4: 1. use snd_ctl_find_id() to get avaliable index; 2. add initial kctl for snd_jack_new(compatible for HDA); 3. add struct snd_jack_kctl * field to struct hda_jack_tbl; 4. new kctls for soc jack during jack pins creating. 5. add a patch to remove exporting snd_kctl_jack_new(). 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.

Some M-Audio devices require to receive bootup command just after powering on, while codes in BeBoB driver doesn't work properly in big-endian machine because the command should be aligned by little-endian. This commit fixes this bug. This fix should go to stable kernel.

[alsa-devel] 1st draft: ALSA Json Gateway and HTML5 UI
by Fulup Ar Foll 07 Apr '15

07 Apr '15

Hi, I would need some help to finish a json version of amixer. Porting cget is done, but for cset I have an issue with "snd_hctl_find_elem (handle, id)". I'm not sure what's the right method to pass it. I've tried every options I could imagine. But if it works on Mint/32bit, it miserably fail on OpenSuse/64. Furthermore amixer.c as this strange comment /* FIXME: Remove it when hctl find works ok !!! */ and they do not use snd_hctl_find_elem. I posted a small C code to highlight the issue at [1]https://gist.github.com/fulup-bzh/891e5627be325150337f My question is simple, did I miss something ? should I move to lower level API ? Note: While the painting for my json-gateway is not dry, I nevertheless pushed a initial running version with cget at [2]https://github.com/fulup-bzh/AlsaJsonGateway I also have a small HTML5/UI at [3]http://breizhme.net/alsajson/mixers/ajg#/scarlett?card=2 While UI code is very dependant on each soundcard [in my case Scarlett/Focurite] the Json-Gateway is 100% independent of the board. If anything one have an idea, please let me know.

[alsa-devel] [PATCH][ASoC]Add ability to remove rate constraints from generic ASoC AC'97 CODEC driver
by Maciej S. Szmigiero 07 Apr '15

07 Apr '15

Add ability to remove rate constraints from generic ASoC AC'97 CODEC driver via passed platform data, make it selectable in config. This way this driver can be used for platforms which don't need specialized AC'97 CODEC drivers while at the same avoiding code duplication from implementing equivalent functionality in a controller driver. There is no change in behavior when no platform data is passed.

Sorry for posting this soo close to the 4.1 merge window, I had completely forgotten about this chunk of work I did earlier this month. The per-user struct clk patches rather badly broke clkdev and various other places. This was reported, but was forgotten about. Really, the per-user clk stuff should've been reverted, but we've lived with it far too long for that. So, our only other option is to now rush these patches into 4.1 and hope for the best.

[alsa-devel] [PATCH] ASoC: davinci-mcasp: Fix ruledata setup in davinci_mcasp_startup
by Peter Ujfalusi 07 Apr '15

Passing &mcasp->ruledata[dir] to snd_pcm_hw_rule_add() is not correct since commit: 7b3d165a2821 ASoC: davinci-mcasp: Index ruledata in drvdata with substream->stream now sets up the struct based on the substream->stream (0 or 1) while we pass a pointer which we take with dir (1 or 2).

[alsa-devel] steinberg ur44 - soundcard not connecting, acl problem (systemd?)
by James Miller 06 Apr '15

06 Apr '15

Hi, I've just bought a steinberg ur44. It is reported as having worked in an earlier kernel to the 3.18 rt custom/3.19 low latency generic that I am using. The low latency kernel is generic but the realtime is compiled with the alsa quirks as described here: http://mailman.alsa-project.org/pipermail/alsa-devel/2014-March/074120.html On plugging it in, the card is recognised by udev but is disconnected after seemingly being set up. The same error seems to be occurring when I start the machine with the card plugged in. There seems to be an ACL error reported in journalctl. I include the appropriate lines from the udevadm and from journalctl udevadm: sudo udevadm monitor monitor will print the received events for: UDEV - the event which udev sends out after rule processing KERNEL - the kernel uevent KERNEL[2741.779546] add /devices/pci0000:00/0000:00:1a.7/usb1/1-5 (usb) KERNEL[2741.779705] add /devices/pci0000:00/0000:00:1a.7/usb1/1-5/1-5:1.0 (usb)

[alsa-devel] [PATCH v3 0/5] Intel SST driver restructure
by Jie Yang 06 Apr '15

06 Apr '15

In order to prepare for the upstreaming of Skylake drivers and to allow reuse of code between different Intel audio DSP products, this patch series restructures the Intel directory as follows: 1. Create "common" directory. Move common files into this directory. 2. Create "boards" directory. Move all machine drivers into this directory. 3. Create "haswell" directory. Move all remaining hsw/bdw code into this directory. 4. Create "baytrail" directory. Move remaining baytrail driver to this directory. 5. Create "atom" directory. Move all MCG platform drivers(including sst/ folder) to this directory. Changes in v3: Fix ATT43256.config 0day build issue. Changes in v2: Add "Reviewed-by" and "Acked-by" items from each platforms' maintainer. Todo next step: 1. Change and move atom related codes(in atom/sst/) to corresponding and try share as many as possible codes(e.g. sst_acpi.c). 2. Share more common codes about IPC for different platforms, e.g. The methods for queueing and sending/reciving Tx/Rx messages, The methods for mailbox IO, The IPC error return codes, etc. Jie Yang (5): ASoC: Intel: create common folder and move common files in ASoC: Intel: create haswell folder and move haswell platform files in ASoC: Intel: create boards folder and move sst boards files in ASoC: Intel: create baytrail folder and move baytrail platform files in ASoC: Intel: create atom folder and move atom platform files in sound/soc/intel/Makefile | 42 +++-------------------

[alsa-devel] [PATCH] ASoC: wm5102: Remove set of volume update bits for output 3R
by Charles Keepax 06 Apr '15

06 Apr '15

The earpiece on wm5102 is mono, thus there is no output 3R. Don't toggle the volume update bits for this output, although worth noting that doing so had no negative effects it is just redundant.

[alsa-devel] SoundBlaster X-fi HD SPDIF fix
by Richard Körber 05 Apr '15

05 Apr '15

Hi! I own a Creative USB SoundBlaster X-fi HD and tried to use its SPDIF optical output. However it didn't work with ALSA out of the box. The reason is that for SPDIF output device #1 must be used. The fix is: In /usr/share/alsa/cards/USB-Audio.conf, change the iec958_device block like this: USB-Audio.pcm.iec958_device { "USB Sound Blaster HD" 1 } Digital output works fine for me after that. BTW, I tried this line in /etc/asound.conf cards.USB-Audio.pcm.iec958_device."USB Sound Blaster HD" 1 but it didn't have any effect. Why was that? Thank you! Regards Richard Körber

[alsa-devel] linux-next - strange audio bug
by Valdis Kletnieks 04 Apr '15

04 Apr '15

Next-20150310 works OK, next-20150324 has the bug. Dell Latitude E6530 laptop, lspci tells me: 01:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev a1) Subsystem: Dell Device 0535 ... Kernel driver in use: snd_hda_intel Symptoms: Audio works perfectly at boot, and for some amount of time after. But somewhere around 6-8 hours of uptime, it gets into a strange state where I'll get no audio... and then it will cut in for all of 2 seconds or so (fairly consistent, that part), and then cut back out for anywhere from 10 seconds to a minute, then another 2 seconds of sound.. lather rinse repeat. Before I start the thankless task of bisecting this (which means I'll be able to do only 1, *maybe* 2 steps a day), does this ring any bells?

[alsa-devel] [PATCH] ALSA: hda - Fix subsystem ID read regression
by David Henningsson 04 Apr '15

A regression was introduced in 7639a06c23c7d4cda3: if AC_PAR_SUBSYSTEM_ID reads as zero, one should retry using AC_VERB_GET_SUBSYSTEM_ID.

[alsa-devel] dummy codec + simple card combination
by Belisko Marek 03 Apr '15

03 Apr '15

Hi, I'm trying to add audio support for gta04 (for gsm + bt and fm audio). All audio sources are clock masters so basically connection is dummy codecs -> cpu dai (mcbsp ports). For implementing such thing I can see 2 options: 1. simple card driver which can easily describe cpu dai interface but dummy codec cannot because there are no DT bindings (there was sever attempts to add DT bindings for dummy-codec but AFAIK none was accepted) This turns it to only solution to create gta04 soundcard which will get from DT cpu dai links and use in card driver dummy codecs directly. Is my assumption correct? I would like to get some feedback before wasting my time with implementing something which cannot be pushed mainline. Thanks for all suggestions.

[alsa-devel] Advanced Gtk+ Sequencer aka GSequencer now on GitHub
by Joël Krähemann 03 Apr '15

03 Apr '15

Hi all, me just migrated gsequencer to GitHub. http://www.gsequencer.org Further me did renamed binary from `ags` to `gsequencer`. About the state of the sequencer: Version 0.4.2-44 is believed to be stable. Since me don't have the time to test it well, me need people to test it. Please, let me know your experiences. MIDI support is intended to be added for release Version 0.4.3 and many other new exciting features. If someone can help with ALSA rawmidi, please let me know. I don't want to do JACK, since it is believed to be somehow the Qt thing. What me can say so far about MIDI me read years ago about it in "The computer music tutorial - The MIT Press, ISBN 0-262-68082-3". And MIDI consist of messages which are routeable. Someone giving specification how the MIDI message struct is passed to ALSA and how it looks like would be great. Thank you in advance Joël

[alsa-devel] [RFC 0/11] dw_hdmi cleanups, audio preparation, helpers and ahb audio support
by Russell King - ARM Linux 02 Apr '15

02 Apr '15

I'm sending this series for comments, and to allow people to update their code bases (for those who are using my AHB audio driver on iMX6). This is really several series, and I'm not expecting this to be ready for the upcoming merge window. That said, if anyone wants to say that they're happy with some of the initial four patches, I'm happy to queue those for David, if he's willing to take them. This series applies on top of my previous series, which finished with the patch "drm: bridge/dw_hdmi: adjust n/cts setting order". The first four patches are a few cleanups to the dw_hdmi driver. The next two patches introduce new interfaces to the dw_hdmi driver to support AHB audio, including the errata found on iMX6 which requires N to be programmed to zero when the audio FIFO is not full. I'm expecting some discussion with these last two as we try to work out how to deal with the two variants of audio support for this part (AHB audio vs I2S audio). The following three add various helpers to the DRM and ALSA subsystems for audio support which is non-specific to the AHB audio driver. For DRM, this is a helper macro to obtain the pointer into the short audio descriptors. For ALSA, it's a set of helpers to restrict an audio PCM device's capabilities according to the ELD, and to generate the IEC958 channel status data. If these helpers are acceptable, we can convert a number of drivers to them. The ELD helper isn't quite finished, but should be sufficient for initial testing. The last two patches add support for the dw_hdmi audio. This is an ALSA driver rather than an ASoC driver as it's a pretty simple affair. I couldn't find a suitable location in the sound/ subtree to place it, so I've placed it next to the bridge - yes, we probably need to find it a better home in the sound/ subtree, but it currently makes use of dw_hdmi.h in the directory it lives. drivers/gpu/drm/bridge/Kconfig | 11 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/dw_hdmi-ahb-audio.c | 566 +++++++++++++++++++++++++++++ drivers/gpu/drm/bridge/dw_hdmi-ahb-audio.h | 14 + drivers/gpu/drm/bridge/dw_hdmi.c | 250 ++++++++----- drivers/gpu/drm/bridge/dw_hdmi.h | 3 + include/drm/bridge/dw_hdmi.h | 7 + include/drm/drm_edid.h | 19 + include/sound/pcm_drm_eld.h | 6 + include/sound/pcm_iec958.h | 9 + sound/core/Kconfig | 6 + sound/core/Makefile | 3 + sound/core/pcm_drm_eld.c | 91 +++++ sound/core/pcm_iec958.c | 70 ++++ 14 files changed, 964 insertions(+), 92 deletions(-) -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net.

[alsa-devel] [PATCH] ASoC: atmel-pcm-dma: increase buffer_bytes_max
by Alexandre Belloni 02 Apr '15

02 Apr '15

atmel-pcm-dma is not limited to a buffer size of 64kB like atmel-pcm-pdc. Increase buffer_bytes_max to 512kB to allow for higher bit rates (i.e. 32bps at 192kHz) to work correctly. By default, keep the prealloc at 64kB.

[alsa-devel] ASoC: cs4271: init/timing problem
by Pascal Huerst 02 Apr '15

02 Apr '15

Hey all, We have a custom built hw, based on am335x and from time to time we need to rmmod/modprobe the ASoC machine driver. Depending on the hw, the first call to regmap_update_bits(..) in cs4271_codec_probe(..) fails with -EREMOTEIO. The error is originated in: drivers/i2c/busses/i2c-omap.c and happens if no i2c package acknowledge is received by the host. I think this is a timing issue and on some devices, the codec is just not ready yet, for communication. What is the right way to fix that? My attempt would be something like this: const int retries = 5; while (retries) { ret = regmap_update_bits(cs4271->regmap, CS4271_MODE2, CS4271_MODE2_PDN | CS4271_MODE2_CPEN, CS4271_MODE2_PDN | CS4271_MODE2_CPEN); if (ret == -EREMOTEIO) { retries--; udelay(1); continue; } else if (ret) return ret; break; } But I might also just add a proper delay before the first call to regmap_update_bits(..) So what is the proper way to handle this? Thanks Pascal

This can work basically like the reconfiguration via sysfs in the above, but it does it before the first codec configuration. A patch file is a plain text file which looks like below: ------------------------------------------------------------------------ [codec] 0x12345678 0xabcd1234 2 [hint] multi_io = no ------------------------------------------------------------------------ The file needs to have a line `[codec]`. The next line should contain three numbers indicating the codec vendor-id (0x12345678 in the example), the codec subsystem-id (0xabcd1234) and the address (2) of the codec. The rest patch entries are applied to this specified codec until another codec entry is given. Passing 0 or a negative number to the first or the second value will make the check of the corresponding field be skipped. It'll be useful for really broken devices that don't initialize SSID properly. The hd-audio driver reads the file via request_firmware(). Thus, a patch file has to be located on the appropriate firmware path, typically, /lib/firmware. For example, when you pass the option `patch=hda-init.fw`, the file /lib/firmware/hda-init.fw must be present Post output of alsa-info.sh after you reboot with early patching You will get headphone playback volume control but loss those surround , center and lfe playback volume controls http://www.intel.com/support/motherboards/desktop/sb/CS-034206.htm Seem your motherboard does not support multistreaming as it is not in the supported list Do this mean that indep_hp should be explicitly disabled for alc662 ?

[alsa-devel] [PATCH v2 0/5] Intel SST driver restructure
by Jie Yang 02 Apr '15

02 Apr '15

In order to prepare for the upstreaming of Skylake drivers and to allow reuse of code between different Intel audio DSP products, this patch series restructures the Intel directory as follows: 1. Create "common" directory. Move common files into this directory. 2. Create "boards" directory. Move all machine drivers into this directory. 3. Create "haswell" directory. Move all remaining hsw/bdw code into this directory. 4. Create "baytrail" directory. Move remaining baytrail driver to this directory. 5. Create "atom" directory. Move all MCG platform drivers(including sst/ folder) to this directory. Changes in v2: add "Reviewed-by" and "Acked-by" items from each platforms' maintainer. Todo next step: 1. Change and move atom related codes(in atom/sst/) to corresponding and try share as many as possible codes(e.g. sst_acpi.c). 2. Share more common codes about IPC for different platforms, e.g. The methods for queueing and sending/reciving Tx/Rx messages, The methods for mailbox IO, The IPC error return codes, etc. Jie Yang (5):
