Reproduction Steps
Play any file and stream the audio to a local pulse enpoint. You would usually use this if you want to play local audio as a different user on a linux workstation
PULSE_SERVER=127.0.0.1 mpv --no-config test.mp4 -vo null -ao pulse
● Video --vid=1 (h264 1280x720 25 fps)
● Audio --aid=1 (aac 2ch 48000 Hz 126 kbps)
AO: [pulse] 48000Hz stereo 2ch float
VO: [null] 1280x720 yuv420p

Audio device underrun detected.
Audio/Video desynchronisation detected! Possible reasons include too slow
hardware, temporary CPU spikes, broken drivers, and broken files. Audio
position will not match to the video (see A-V status field).
Consider trying `--profile=fast` and/or `--hwdec=auto` as they may help.
Audio device underrun detected.
Expected Behavior
When testing under Fedora 42 in a clean podman environment
podman run --rm -it --network host fedora:42
dnf install ffmpeg mpv
PULSE_SERVER=127.0.0.1 mpv --no-config test.mp4 -vo null -ao pulse
Audio streams without any interruption or stutter.
Actual Behavior
Video playback suffers if enabled and the audio breaks up.
Tested with mplayer/ffmeg and firefox and google-chrome browsers with PULSE_SERVER defined with no playback issues.
Also re-tested with a clean build of 0.41 from git
