** Summary changed: - No sound from internal card chtmax98090 - missing UCM2 files in alsa-ucm-conf 1.2.2, available in alsa-ucm-conf 1.2.3 + [SRU]No sound from internal card chtmax98090 - missing UCM2 files in alsa-ucm-conf 1.2.2, available in alsa-ucm-conf 1.2.3 ** Also affects: alsa-ucm-conf (Ubuntu Groovy) Importance: High Assignee: Hui Wang (hui.wang) Status: Confirmed ** Also affects: alsa-ucm-conf (Ubuntu Focal) Importance: Undecided Status: New ** Description changed: + [Impact] + There is no ucm for ASUS C300 in the 20.04 and 20.10, as a result, + the audio doesn't work on this machine after installing the 20.04 or + 20.10. + + [Fix] + The ucm files for this machine are in the alsa-ucm-conf 1.2.3, + cherry-pick them to ubuntu 20.04 and 20.10 + + [Test Case] + After booting up, use speaker to play some sound, it works well, + plug a headset, play sound to headphone, it basically works but has + some crankling noise, it is a kernel issue for this noise. + + [Regression Risk] + This SRU adds new ucm files, If the machine uses the audio driver + of chtmax98090, it will apply this new added ucm files, there will + be speaker/headphone in the UI. So the possible regression is with + this SRU, users could see the audio devices in the UI but the audio + doesn't work (without this SRU, users couldn't see the audio devices + in the UI at all and the audio doesn't work). This possibility is + low since we tested it on the ASUS C300. + + Asus C300 (repurposed chromembook - bios flashed by Mr.Chromebox script) - Kubuntu Focal minimal fresh installation. The sound card is detected: I see it in the Plasma Widget, in pavucontrol, in alsamixer and it's not muted. I tried and add in /usr/share/alsa/ucm/chtmax98090/ the old style use case config files: no success. I tried and unmute speakers left and right in alsamixer: no success. I rapidly tested Ubuntu Mate Focal fresh install: I had exactly the same issue. I'm running on the same rig Debian Bullseye, kernel 5.4: sound card output and input are both working perfectly - I noticed that in Kubuntu alsamixer Kubuntu when I open it I have an entry HDA IntelPCH (the HDMI card), while in Debian I find Pulseaudio. - I attach the alsa-info.sh output.
