Update: (only after overnight hibernation) :: No sound on external USB audio device after hibernation, but still sound with internal HDA

PRECONDITIONS:

  1. I've purged plasma-pa, pavucontrol, pavucontrol-qt. Because I had similar issues after the user session was locked. This problem has gone now. Below is an hibernation issue which affects ALSA.

  12. Switching to mplayer video: Still nothing happens when trying to play back the video. Still freezed.
  13. Closed mplayer.
  14. Opened mplayer with: PIPEWIRE_DEBUG=3 mplayer $VIDEO.mp4
  15. Yes. I do have sound with the external USB sound device.
