Update after the latest firmware update for the platform, called AMD AGESA V2 PI 1.2.0.3 Patch A, released yesterday for my platform, finally. This includes the USB patch for the drop in the USB communication under load for too much recovery errors hitting the Pci-Ex subsystem on the chipset, apparently, that was only present when using Pci-Ex 4 (B5xx and X5xx, not on b4xx, in theory).
However, the USB issues was still present even on older platform, apparently. Just not as grave as the 500 series. The audio clicking is completely gone and the machine is finally much more responsive; I've yet have to test the system under high loads, but even on the desktop the audio clicking was audible sometimes, when event from application fires; after the firmware update, this is completely disappeared. The audio now is perfect, at least in output. I'll update here as soon as I can test the recording now. I didn't think it would change much. But, for me at least, it did. -- 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
