Description Yuri 2016-07-21 23:45:24 UTC

On one FreeBSD laptop mpv plays video much faster when pulseaudio is enabled (--ao pulse). With --ao oss the speed is normal. Clock itself there runs with the normal speed.

It appears that pulseaudio is what causes it, but I don't understand the mechanism. It is also unclear why the overall playing speed depends on the pulseaudio which only plays sound.

I already asked this question on hackers@ FreeBSD ML but so far got no answer: https://lists.freebsd.org/pipermail/freebsd-hackers/2016-July/049762.html

My bug report for mpv was labaled as "not_our_bug" https://github.com/mpv-player/mpv/issues/3353

paplay plays simple sounds fine.

This bug makes mpv pulseaudio completely unusable with pulseaudio.

It really isn't clear at all what the problem might be. I doubt the problem is in PulseAudio, but I don't want to do another round of passing on the buck, so could you please generate verbose logs on the server side (pacmd set-log-level 4, see output in syslog) while also generating verbose output from mpv, for the media that doesn't work.
