@Hui There's no sound recording difference within Debian 1.2.3 and yours testing 1.2.2
I narrowed down the issue: it's coming along when plugging / unplugging the headset jack while I'm running the recording piece of software. I'm able to reproduce the issue on Audacity. This issue makes web Skype unusable, the installed version of Zoom seems to work of I plug the jack in before launching it. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to alsa-ucm-conf in Ubuntu. https://bugs.launchpad.net/bugs/1871306 Title: No sound from internal card chtmax98090 - missing UCM2 files in alsa- ucm-conf 1.2.2, available in alsa-ucm-conf 1.2.3 Status in alsa-ucm-conf package in Ubuntu: Confirmed Bug description: 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.
