Source: linux Version: 5.14-1~exp1 Severity: normal Tags: upstream In kernel 5.13 on my Rock64, `pactl list cards` correctly identified my AVR (SC-1224) and had various multichannel audio profiles I could choose from. Since kernel 5.14, `paclt list cards` no longer identifies my AVR and I only have stereo audio profiles. I've build and tested various kernel versions myself based off commit e4e2aea3e840406042537c5ef4970d9e8560a103 (Merge branch 'rockchip-spdif' into 'master') which has all needed audio modules (afaik) enabled for Rock64. The 5.13.12-1~exp2 is slightly older and therefor misses the SPDIF card. I used the same dtb in all the test, which is build from 5.14.6, and I've kept all other software at the same sofware versions, so it wouldn't affect the results. I think that means the only (real) change is the upstream source code.

Yes, you understood correctly. I (previously) used HDMI.conf/SPDIF.conf (and also had 2 other .conf files) taken from the LibreELEC repo which actually made multi-channel audio work in kernel versions < 5.14. In kernel 5.14 the card name was hard-coded to "simple-card" and so it couldn't find a matching .conf file and therefor the audio profile changed to "stereo-fallback". In the following commit, the LE people created a "simple-card.conf" file and with that I had my multichannel audio back: https://github.com/LibreELEC/LibreELEC.tv/commit/f681a48a664bd0f0e8f0dc131bd58c5d7512adc3 I _think_ that it would be (even) better if an UCM configuration file gets created, but I don't know how to do it and whether such a file should be created for each card, which to me doesn't rhyme with Use Case. I'm not sure whether I'll make time to figure out how/what/where/why/etc needs to be done to do it proper. In https://github.com/LibreELEC/LibreELEC.tv/issues/5734#issuecomment-940088156 I had verified that it indeed fixed the issue for me with a self-compiled kernel (from ~ Debian's 'master' branch) and today I verified that the latest LE nightly is also again working as it should. Thanks for the reminder :) Cheers, DiederikAttachment: signature.asc
