Hmm... I am noticing something strange between old and new kernels. Without any patch applied, on the kernel 5.2.5 as Marco said, is working fine after a couple of seconds (with or without position-fix=3) BUT a little bit of sound distortion is present without the Iwai patch 6.
On older kernels than 5.2.5 like 4.19.63 the output issue "disappears" with Iwai's patch after a minute, so it takes longer. I think the issue is on the playback, because when I open Discord even the system audio crackles. But still I'm not sure. Is it possible newer kernels already have a partial workaround? I also noticed the patch modifies less lines on 5.2.5. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1801540 Title: Microphone distorted sound on ALC892/1220 on AMD chipsets Status in Linux: Confirmed Status in linux package in Ubuntu: Won't Fix Status in pulseaudio package in Ubuntu: Won't Fix Bug description: Not sure if I'll report this upstream but there is definitely an issue with microphone recording on my desktop, this is not happening on my laptop which has a different codec. Already tried all workarounds possible, no luck. Only with my desktop with this particular motherboard. No issues in Windows, the sound recorded in there is distorted and has some static and robotic tone on high-pitch. alsa-info on the attachments To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1801540/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
