I can't believe it, it works now with position_fix = 3! I don't know if this was caused by the additional patch to the kernel, I'll probably try to remove it to see if it is still working with 3, but I had already tried all position fix and a heap of other stuff. The audio now is perfect, even with pulseaudio :) This is the result that you have requested anyway: 0: Same problem, no other issues 1: Same problem, no other issues 2: Unable to acquire stream, arecord signal overrun!!! (at least 377,780 ms long) and no audio is acquired 3: No clicking in the acquired stream! 4: Same problem, no other issues -- 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
