Does this happen if you use use a different AO?

I had a similar issue which came with the version after 0.33.1-3 in arch.

Following the suggestion, I switched from pipewire back to pulseaudio and the issue was fixed (at least for me).

Let me know if you need any more info, happy to test

This could be fixed by #10356

Going to assume this was a pipewire pulse emulation thing that has since been fixed since this is old and there haas been a lot of work since then. Feel free to reopen if this is not the case.

I'm having this problem too after deciding to remove my old mpv version on Ubuntu 22.04 LTS then building it from source into a deb package myself. Pipewire doesn't come with Ubuntu 22.04, but I enabled it myself with pipewire-pulse.

So far, adding an ao=pulse line to mpv.conf seems to have remedied the issue. I'll report back if something else goes wrong, but that seems to be the fix for me
