I notice the following in the log with patch 7: Also, I don't know if it's expected but enabling 'mic boost' produces a lot of noise.
pulseaudio[3370]: E: [alsa-source-ALC1220 Analog] alsa-source.c: We were woken up with POLLIN set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. pulseaudio[3370]: E: [alsa-source-ALC1220 Analog] alsa-source.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. pulseaudio[3370]: E: [alsa-source-ALC1220 Analog] alsa-source.c: ALSA woke us up to read new data from the device, but there was actually nothing to read. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1801540 Title: Microphone distorted sound on ALC892/1220 on AMD chipsets To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1801540/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
