aplay: add support for G.711 A_LAW enconding in AU file format
by GitHub pull_request - opened 02 Apr '25

02 Apr '25

alsa-project/alsa-utils pull request #297 was opened from chleroy: At the time being, aplay only supports G.711 µ-law, 8-bits PCM and 16-bits PCM encodings for the AU format while the AU format supports many more. In Europe the most G.711 used encoding is the A-law, which is also part of the encodings supported by the AU file format. Add support for that encoding in aplay.

[PATCH alsa-ucm-conf 1/2] sof-soundwire: cs42l43: Drop headset mic from mic mute LED
by Maciej Strozek 01 Apr '25

As per conversation in [1], let headsets be dropped from LED bindings. Also remove turning off the mics on device disable since they are now not needed.
