Tried that already.

Based on the report, this seems to be an actual bug - it was working fine for everyone before the update and only happens in the presence of FluidSynth.

Ubuntu probably hasn’t had this version of PipeWire yet.

My work around is working just fine for now, though.

I’ve done it with ffmpeg before - I think the command’s on the Arch wiki. I preserved subtitles as well. I overall remember it being pretty reasonable since I didn’t set it up to re-encode, just pass through original video.
