Hm, interesting, AZX_DCAPS_POSFIX_LPIB basically sets the position reporting based on LPIB instead of the position buffer. I thought the position buffer isn't available or unreliable on non-Intel chips, but it might be different on the recent AMD one.
FWIW, you can change the behavior via position_fix option, too. This is an array for multiple instances, so be careful if you have multiple HD-audio devices (likely on AMD). If you pass a non-default value (e.g. 2, which means to forcibly use the position buffer) to the second card, pass like position_fix=,2 note the comma before "2". AZX_DCAPS_SYNC_WRITE should be likely OK. It essentially enables the sync after each write for the codec communication stability, i.e. it assures each command verb is executed and waiting for the response of that command. We're going to enable this flag even for Intel chipsets, too. -- You received this bug notification because you are a member of Desktop 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/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
