by Shengjiu Wang 25 Sep '19

25 Sep '19

This patch serial is to update the supported format for fsl_asrc and fix some format issue. Shengjiu Wang (4): ASoC: fsl_asrc: Use in(out)put_format instead of in(out)put_word_width ASoC: fsl_asrc: update supported sample format ASoC: pcm_dmaengine: Extract snd_dmaengine_pcm_refine_runtime_hwparams ASoC: fsl_asrc: Fix error with S24_3LE format bitstream in i.MX8 changes in v2 - extract snd_dmaengine_pcm_set_runtime_hwparams in one separate path. - 4th patch depends on 3rd patch changes in v3 - Fix build report by kbuild test robot <lkp(a)intel.com> - change snd_dmaengine_pcm_set_runtime_hwparams to snd_dmaengine_pcm_refine_runtime_hwparams changes in v4 - update according to Nicolin's comments. include/sound/dmaengine_pcm.h | 5 ++ sound/core/pcm_dmaengine.c | 83 +++++++++++++++++++++++++++ sound/soc/fsl/fsl_asrc.c | 65 ++++++++++++++------- sound/soc/fsl/fsl_asrc.h | 7 ++- sound/soc/fsl/fsl_asrc_dma.c | 59 ++++++++++++++++--- sound/soc/soc-generic-dmaengine-pcm.c | 61 ++------------------ 6 files changed, 193 insertions(+), 87 deletions(-) -- 2.21.0

[alsa-devel] Making alsamixer configurable, adding mouse support + minor fixes
by GitHub pull_request - opened 24 Sep '19

24 Sep '19

alsa-project/alsa-utils pull request #26 was opened from braph: Hello, I'm using the alsamixer, but I am missing mouse support and the ability to configure it. I implemented those things for myself now, maybe it would also be useful for others. There are some commits that would even fit in the original alsamixer code without my rather heavy modifications, these are: 6eb0bc8f0848567f302e94ea5ee3a6d7c6966e65: _alsamixer: remove redundant sprintf() calls_ bef5b723a43f310ba73bcaa52f3da74ef5e08dde: _alsamixer: use mvwhline/mvwvline for drawing lines_ ae0604c93aa4bacbb678eb8ec832ad9e17c8b56a: _alsamixer: device_name.c: recognize DEL (ASCII 127) as backspace_ And maybe 485f3b0da1ffead2f88cffd9f2203516000415b5: _alsamixer: fix window_size_changed()_ Regards, Benjamin Request URL : https://github.com/alsa-project/alsa-utils/pull/26 Patch URL : https://github.com/alsa-project/alsa-utils/pull/26.patch Repository URL: https://github.com/alsa-project/alsa-utils

[alsa-devel] alsa-ucm-conf repository - initial import
by Jaroslav Kysela 24 Sep '19

24 Sep '19

Hello all, I just made an initial import to to alsa-ucm-conf repository which is in the 'import' branch: https://github.com/alsa-project/alsa-ucm-conf/tree/import I do not have the BSD-3-Clause licence acknowledgements from some minor contributors. I do not think that it's a problem. I would expect that if we do not have a disagreement, it is fine. The question is, if we need automake/autoconf tools to package those files. It seems to me that it might be clever to keep this ASIS for now. Users/packagers can just do 'cp' to the appropriate directory.

[alsa-devel] Propagating audio properties along the audio path
by Marc Gonzalez 24 Sep '19

24 Sep '19

Hello everyone, Disclaimer: I've never worked in the sound/ layer, and it is possible that some of my questions are silly or obvious. Basically, I'm trying to implement some form of eARC(*) on an arm64 SoC. (*) enhanced Audio Return Channel (from HDMI 2.1) The setup looks like this: A = Some kind of audio source, typically a TV or game console B = The arm64 SoC, equipped with some nice speakers HDMI A ------> B If we look inside B, we actually have B1 = an eARC receiver (input = HDMI, output = I2S) B2 = an audio DSP (input = I2S, output = speakers) I2S ? B1 -----> B2 -----> speakers If I read the standard right, B is supposed to advertise which audio formats it supports, and A is supposed to pick "the best". For the sake of argument, let's say A picks "PCM, 48 kHz, 8 channels, 16b". At some point, B receives audio packets, parses the Channel Status, and determines that A is sending "PCM, 48 kHz, 8 channels, 16b". The driver then configures the I2S link, and forwards the audio stream over I2S to the DSP. QUESTION_1: How is the DSP supposed to "learn" the properties of the audio stream? (AFAIU, they're not embedded in the data, so there must be some side-channel?) I assume the driver of B1 is supposed to propagate the info to the driver of B2? (Via some call-backs? By calling a function in B2?) QUESTION_2: Does it ever make sense for B2 to ask B1 to change the audio properties? (Not sure if B1 is even allowed to renegotiate.) Regards.
