@Hui I updated today to 20.10 and tested. With the official alsa-ucm-conf 1.2.2 and with the official kernel the sound works. However I needed to use alsamixer manually to manage the volume levels when plugging in and out the headset jack.
I didn't find a Groovy build of the testing 1.2.2 in your ppa, therefore I installed alsa-ucm-conf 1.2.3 from Debian testing, rebooted and a perfectly working sound was back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1871306 Title: [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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-ucm-conf/+bug/1871306/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
