Public bug reported:
On Ubuntu 25.04, MPV using PipeWire audio output (ao=pipewire) produces
no sound, despite wpctl status showing unmuted sink (ID 35,
Starship/Matisse HD Audio Controller Analogue Stereo, vol: 1.00).
PulseAudio (-ao pulse) and ALSA (-ao alsa) work fine. Added ao=pipewire
and audio-channels=2 to ~/.config/mpv/mpv.conf, reinstalled pipewire,
pipewire-pulse, wireplumber, and tested --audio-
device=pipewire/alsa_output.pci-0000_09_00.4.analog-stereo with no
success. PipeWire logs show xrun errors, suggesting buffer issues.
Adding audio-buffer=0.1 to mpv.conf didn't help. Using -ao pulse as
workaround.
Sound is enabled in Brave or Spotify - which I assume they are just
using pulse or alsa
