Did some tests using the AUR package snd_hda_intel-alc1220-dkms (Seems to be Patch 2) on the 1022:1457 ALC1220 (X370 Pro Carbon motherboard). Using the default settings i no longer hear the robotic echo issues in my microphone recordings and i am able to get good recordings with Audacity. tsched=0 seems to have feint audio issues which are similar to my best case scenario without the patch. It is hard to hear and could be a tsched=0 only issue.
However more worryingly i was able to reproduce my former Audacity "Dolphin speed" issue where it records way faster than it should. While not present by default this happens after i use pulseaudio -k and then try to use Audacity. This does not happen on my laptop with an Intel Motherboard and connexant audio chip indicating it is still driver related. The effect happens both on the "pulse" microphone and on the direct microphone when selected. Perhaps this is already resolved in the future patches, but i found this an easy to replicate testing scenario to see if underlying bugs are present. -- 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
