[SOLVED] radio stream with mpv: Audio device underrun detected
I used to hear radio live streaming with mpv.
After system update at 2023-08-04_143246 (no mpv update) I get an
Audio device underrun detected.
but only after listening 7..9 minutes, before it's fine. The audio stops for a second, then plays, then stops...
During the last 2 minutes before the underrun I can see the mpv cache is degrading from ~ 10 seconds to 0, then the underrun occurs.
Viewing an live TV stream reduces the time to buffer underun to 2-3 minutes.
mpv with "--cache=no" is a workaround.
vlc works with the same radio live streaming.
Any hints or ideas, which package could be the root cause or which changed setting I missed ?
tested today after fully upgrade with

Re: [SOLVED] radio stream with mpv: Audio device underrun detected
Thank very much!
Yes, seems this is my bug, core/glibc 2.38-1 / posix_memalign regression.
I'm using yt-dlp too, and, since mentioned, I see also the high cpu usage too.
The mentioned workaround
LD_PRELOAD=`jemalloc-config --libdir`/libjemalloc.so.`jemalloc-config --revision` mpv ...works for me.
I will set this to solved and wait for a bugfix from upstream.
Have a great weekend !
