[PATCH -next] ASoC: pcm512x: Fix PM disable depth imbalance in pcm512x_probe
by Zhang Qilong 29 Nov '22

29 Nov '22

The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by going to err_pm instead of err_clk.

[PATCH 00/11] ASoC: Intel: avs: Refactor jack handling
by Cezary Rojewski 29 Nov '22

29 Nov '22

For all the boards included in this patchset, a similar set of changes is proposed: 1) Move jack unassignment from platform_device->remove() to dai_link->exit(). This is done to make jack init and deinit flows symmetric 2) Remove platform_device->remove() function 3) Simplify card->suspend_pre() and card->resume_post() by making use of snd_soc_card_get_codec_dai() helper While bdw_rt286 board - which is utilized by the catpt-driver - is definitely not part of "avs", same treatment applies. And thus decided to make it part of this series instead of sending it separately.

[PATCH] selftests: alsa - move shared library configuration code to conf.c
by Jaroslav Kysela 29 Nov '22

29 Nov '22

The minimal alsa-lib configuration code is similar in both mixer and pcm tests. Move this code to the shared conf.c source file. Also, fix the build rules inspired by rseq tests. Build libatest.so which is linked to the both test utilities dynamically. Also, set the TEST_FILES variable for lib.mk.

[PATCH v2] ALSA: usb-audio: Add quirk for Tascam Model 12
by John Keeping 29 Nov '22

29 Nov '22

Tascam's Model 12 is a mixer which can also operate as a USB audio interface. The audio interface uses explicit feedback but it seems that it does not correctly handle missing isochronous frames. When injecting an xrun (or doing anything else that pauses the playback stream) the feedback rate climbs (for example, at 44,100Hz nominal, I see a stable rate around 44,099 but xrun injection sees this peak at around 44,135 in most cases) and glitches are heard in the audio stream for several seconds - this is significantly worse than the single glitch expected for an underrun. While the stream does normally recover and the feedback rate returns to a stable value, I have seen some occurrences where this does not happen and the rate continues to increase while no audio is heard from the output. I have not found a solid reproduction for this. This misbehaviour can be avoided by totally resetting the stream state by switching the interface to alt 0 and back before restarting the playback stream. Add a new quirk flag which forces the endpoint and interface to be reconfigured whenever the stream is stopped, and use this for the Tascam Model 12. Separate interfaces are used for the playback and capture endpoints, so resetting the playback interface here will not affect the capture stream if it is running. While there are two endpoints on the interface, these are the OUT data endpoint and the IN explicit feedback endpoint corresponding to it and these are always stopped and started together.

stop drivers from passing GFP_COMP to dma_alloc_coherent
by Christoph Hellwig 29 Nov '22

29 Nov '22

Hi all, this series fixes up various drivers that either try to get a compound page from dma_alloc_coherent or more often just did a bit of cargo cult copy and paste, and then warns about this flag passed in the DMA layer instead of silently clearing it like done by ARM and dma-iommu before.
