<pre>Sorry for the delay on my part also.
So the error was "Operation not permitted". That means that a thread tried to

Are you familiar with getting backtraces with gdb? mpv's pulse output is
working fine for me, and finding the exact code that fails requires a
backtrace. There are some instructions here (but instead of running pulseaudio
inside gdb, you need to run mpv inside gdb):
