Add Use Case for Arturia Minifuse 2
by GitHub pull_request - opened 03 Apr '22

03 Apr '22

alsa-project/alsa-ucm-conf pull request #145 was opened from nodens: Arturia Minifuse 2 (https://www.arturia.com/products/audio/minifuse/minifuse2) is an USB audio interface with 2 mono inputs and 2 channel outputs. It uses 1 subinterface with 4 capture and 4 playback channels: Capture channels: - Mic/Line/Inst 1 (Mono) - Mic/Line/Inst 2 (Mono) - Loopback (Stereo, L+R) Playback: - Main (Stereo, L+R) - Loopback (L+R) The Loopback capture and playback are intended to ease recording sound from the computer, e.g if you're doing a podcast and want to record something that plays from the computer. Of course us linux user don't need that, since we have many tools able to do that. However, without a dedicated use case, alsa treats the channels as surround 4.0, which make the card difficult to use. At this stage, no controls are available. TODO/FIXMEs: - add a channel map override on the pcm device ?

[PATCH RFC 0/2] Make headphone work on Huawei Matebook D15
by Mauro Carvalho Chehab 03 Apr '22

03 Apr '22

The headphone output at Huawei Matebook D15 is controlled by a separate GPIO than the speaker. So, the es8336 boards logic need to handle two events: one for the speaker switch and another one for the headphone. Please notice that this is my first real incursion at SOC/SOF. While this is working fine, I'm still struggling with some troubles with pipewire, which I believe are due to UCM support, as, sometimes when pavucontrol starts, the playback stucks. Also, sometimes the mixers won't change when jack plug/unplug is detected. So, more debug is needed, and probably the UCM will also need to be closer to the definitions that are used at ucm2/codecs/es8316/, as es8336 is a variant of it. Anyway, let me submit this as as RFC, in order to get some feedback if this is going at the right way to support the headphone switch event.
