[alsa-devel] [PATCH 1/2] ASoC: cs42xx8: Do not use rtd->codec
by Lars-Peter Clausen 19 May '14

19 May '14

rtd->codec does not necessarily point to the CODEC instance for which the callback was called (e.g. for CODEC<->CODEC or multi-CODEC links). Use dai->codec instead.

[alsa-devel] [PATCH V2] ASoC: SAMSUNG: Add sound card driver for Snow board
by Tushar Behera 19 May '14

19 May '14

Added machine driver to instantiate I2S based sound card on Snow board. It has MAX98095 audio codec on board. There are some other variants for Snow board which have MAX98090 audio codec. Hence support for MAX98090 is also added to this driver. Signed-off-by: Tushar Behera <tushar.behera(a)linaro.org> --- Changes for V2: Addressed various comments from Mark Brown. 1. Moved DAIFMT flags to dai_link. Removed snd_soc_dai_set_fmt calls. 2. Removed BCLK settings. 3. Moved sysclk settings to late_probe. 4. Removed now empty snow_hw_params. 5. Removed snow_init 6. Used devm_snd_soc_register_card. Also removed empty remove function. 7. Removed non-DT handling as the driver is DT only. Additional nits: 1. Renamed snow_driver_probe to snow_probe 2. Removed unused pm_ops. 3. Updated clock settings for I2S block (Earlier it was I2S_CDCLK, whereas it should be I2S_RCLKSRC_0). 4. Removed 'card-name' DT property as it was not used in earlier sound-card driver DT bindings. Will be added later.

[alsa-devel] [PATCH] ALSA: pcm_dmaengine: Add check during device suspend
by Tushar Behera 19 May '14

19 May '14

Currently snd_dmaengine_pcm_trigger() calls dmaengine_pause() unconditinally during device suspend. In case where DMA controller doesn't support PAUSE/RESUME functionality, this call is not able to stop the DMA controller. In this scenario, audio playback doesn't resume after device resume. Calling dmaengine_pause/dmaengine_terminate_all conditionally fixes the issue. It has been tested with audio playback on Samsung platform having PL330 DMA controller which doesn't support PAUSE/RESUME.

As far as I understand it we do not have to do anything for TRIGGER_SUSPEND if we do not set the SNDRV_PCM_INFO_RESUME flag. It looks like TRIGGER_SUSPEND is called unconditionally during suspend. But since the error code is ignored it should be fine if we just call dmaengine_pause() and that return -ENOSYS or similar. Are you seeing an actual issue that you are trying to fix with your patch? - Lars

[alsa-devel] [PATCH 0/13] make return of 0 explicit

Sometimes a local variable is used as a return value in a case where the return value is always 0. The result is more apparent if this variable is just replaced by 0.

[alsa-devel] Segfaults in snd_pcm_area_silence() when using softvol
by Tanu Kaskinen 18 May '14

18 May '14

Hi, A bug was reported to pulseaudio about a segfault in alsa-lib code when using softvol: https://bugs.freedesktop.org/show_bug.cgi?id=51060 . It has been observed by several people, and this mail was prompted by the last bug comment, which rightly recommends getting in touch with the alsa developers: > I've had this problem too and the problem only occurs with > -ftree-vectorize. > > It looks to me as if this is a gcc bug, as it produces a "movdqa" or > "vmovdqa" instruction which is used with an unaligned pointer. > > Now, I have no clue why gcc assumes the pointer would be an aligned > one, maybe it is even right and something else is wrong, but I haven't > spent too much time digging into this. > > (note that it still happens with gcc 4.7 and the current 4.8 > development one) > > Also, this bug should probably be brought up with the alsa guys as > well, as I don't think pulseaudio is at fault here.
