@Hui alsa-ucm-conf 1.2.3 from Debian Bullseye and mainline kernel generic 5.8.13 eliminate garbling/crackling sound: plugging and un plugging the headset works perfectly, Skype is working as expected.

@Mathi I have the same problem, I thought it was related to plugging/unplugging the headset jack (see comment #28 and following ones). Hui's and my opinion is the it's not alsa-ucm-conf related, therefore this requires more analysis and a new bug report. What you could do: - to play with parameters in alsamixer (it does not work with me) - to test a more recent mainline kernel (not tested yet) - to install alsa-ucm-conf 1.2.3 from Debian (not tested yet) Post your testing results please. -- 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: 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

thanks for working on this @Hui and @Gabirele Today i added ppa:hui.wang/pa-testing and installed alsa-ucm-conf followed by an "apt update; apt upgrade" when i rebooted the system after that, i was so happy to have the sound working. sound worked from browser (while watching youtube videos) and also from media players. But when I opened the pulse audio volume control, i noticed a strange behavior. Suddenly the sound became garbled. I could still hear the sound but it was very garbled. Same behavior observed when i tried to do a zoom conference. The sound on zoom was also very much garbled.

@Hui Ok thanks. Last night I re installed from scratch Ubuntu 20.04.1 and I noted a variation: to make the sound to work I needed to add your testing repo and to do an upgrade.

@Hui Agreed, your backport in 1.2.2 testingvis working as well as the 1.2.3 from Debian Bullseye. It definitively makes sense to submit the 1.2.2 testing to the Ubuntu packagers. Do I need to file a bug against Groovy same issue or is the 1.2.2 is automatically included in Groovy too? I'll check more in deep the crackles issue and if it's the case I'll file new bug.

@Gabirele, Looks there is no difference between Debian 1.2.3 and testing 1.2.2, so should I submit the testing 1.2.2 to ubuntu package?

@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.

@Gabriele, It will also upgrade the pulseaudio, but that pulseaudio will not bring any impact on your machine. Did you experience the same crackling and low volume with the alsa-ucm- conf 1.2.3 from Debian? If Debian version doesn't have this problem, Could you diff my testing version with Debian version?
