I have recently updated to ubuntu 22 and though my headphone sound working fine, laptop speaker is not working. So I went through askubuntu page and followed this tutorial ubuntu 22.04 audio output not working (dummy audio)

And now even my headphone sound is not working. It continues to produce weird radio sound. The sound continues even when I am restarting the OS. It only stops when laptop power went off. Do you guys have any idea? would help alot. Thank you!

  • This is likely a sink/source misconfiguration (see https://unix.stackexchange.com/questions/449690/pulse-audio-virtual-sinks-changing-on-alsa-underrun#450114 & https://stackoverflow.com/questions/52311637/pulseaudio-setting-up-sinks-and-sources-for-a2dp-and-hfp-connections) but you'll have better luck if you report the problem to kernel bug tracker with a full report of your HW specs (which you didn't provide any) – Matias N Goldberg Oct 23 '22 at 14:09
