[alsa-devel] [V2 PATCH] ALSA: hda - Add Dell headset detection quirk for one more laptop model
by Hui Wang 18 Dec '13

18 Dec '13

On the Dell machines with codec whose Subsystem Id is 0x10280640, no external microphone can be detected when plugging a 3-ring headset. Using ALC255_FIXUP_DELL1_MIC_NO_PRESENCE can fix this problem. The codec (Vendor ID: 0x10ec0255) on the machine belongs to alc_269 family.

On the Dell machines with codec whose Subsystem Id is 0x10280640, no external microphone can be detected when plugging a 3-ring headset.

[alsa-devel] USB sound auto-suspend not working
by Sarah Sharp 18 Dec '13

18 Dec '13

Hi Oliver and Takashi, I've noticed that in the last couple kernel releases or so, I can't get USB webcams to suspend. It turns out that the USB sound interface is keeping the device active, even when the device is not playing sound. This goes back as far as 3.10, but I haven't tried older kernels. This is testing on Ubuntu 13.10. Commit 88a8516a2128a6d078a106ead48092240e8a138f "ALSA: usbaudio: implement USB autosuspend" went into kernel 2.6.39. The commit message says the device is prevented from suspending if the pcm or midi channel files are open. I plugged in a USB speaker, and ran lsof to see which files were open (output is attached). AFAICT, only the USB sound device's control files are open, and I don't have any midi files. Any ideas as to why USB sound auto-suspend isn't working? Sarah Sharp

[alsa-devel] [PATCH][RESEND] ALSA: Add SNDRV_PCM_STATE_PAUSED case in wait_for_avail function

When the process is sleeping at the SNDRV_PCM_STATE_PAUSED state from the wait_for_avail function, the sleep process will be woken by timeout(10 seconds). Even if the sleep process wake up by timeout, by this patch, the process will continue with sleep and wait for the other state.

[alsa-devel] [PATCH] ASoC: kirkwood: Fix the CPU DAI rates

This patch fixes the rates declared in the CPU DAI parameters: - SNDRV_PCM_RATE_KNOT and the discrete rates SNDRV_PCM_RATE_xxx should not be used with SNDRV_PCM_RATE_CONTINUOUS, - SNDRV_PCM_RATE_CONTINUOUS asks for rate_min and rate_max, - the device may do streaming down to 5512Hz.

[alsa-devel] [PATCH] ASoC: dmaengine: Add config parameter NULL check.
by Xiubo Li 17 Dec '13

17 Dec '13

Because the "ASoC: dmaengine-pcm: Provide default config" has provided us one defualt config of DMA. When using this, the config parameter of devm_snd_dmaengine_pcm_register() will be NULL, so here we need to have a check before using it.
