[PATCH] ASoC: SOF: ipc4-topology: No need to unbind routes within a pipeline
by Peter Ujfalusi 28 Jan '23

From: Ranjani Sridharan <ranjani.sridharan(a)linux.intel.com> The FW currently ignores unbinding routes if the source and sink widgets belong to the same pipeline.

[PATCH 1/4] ASoC: codecs: tas5720: split a tas5720_mute_soc_component() function

This is to be re-used in tas5720_mute() (which is part of the dai_ops) and also in the tas5720_fault_check_work() hook. The benefit here isn't too great (now).

[PATCH 0/6] Fix default DMIC gain on AMD PDM drivers
by Mario Limonciello 27 Jan '23

27 Jan '23

It's been reported that a number of laptops have a low volume level from the digital microphone compared to Windows. AMD offers a register that can adjust the gain for PDM which is not configured at maximum gain by default. To fix this change the default for all 3 drivers to raise the gain but also offer a module parameter. The module parameter can be used for debugging if the gain is too high on a given laptop. This is intentionally split into multiple patches for default and parameter so that if the default really does behave better universally we can bring it back to stable too later.

[PATCH] ALSA: hda/hdmi: Use only dynamic PCM device allocation
by Jaroslav Kysela 27 Jan '23

27 Jan '23

Per discussion on the alsa-devel mailing list [1], the legacy PIN to PCM device mapping is obsolete nowadays. The maximum number of the simultaneously usable PCM devices is equal to the HDMI codec converters. Remove the extra PCM devices (beyond the detected converters) and force the use of the dynamic PCM device allocation. The legacy code is removed. I believe that all HDMI codecs have the jack sensing feature. Move the check to the codec probe function and print a warning, if a codec without this feature is detected.

[PATCH] [v2] ASoC: cs42l56: fix DT probe
by Arnd Bergmann 26 Jan '23

26 Jan '23

From: Arnd Bergmann <arnd(a)arndb.de> While looking through legacy platform data users, I noticed that the DT probing never uses data from the DT properties, as the platform_data structure gets overwritten directly after it is initialized. There have never been any boards defining the platform_data in the mainline kernel either, so this driver so far only worked with patched kernels or with the default values. For the benefit of possible downstream users, fix the DT probe by no longer overwriting the data.
