PulseAudio causes timing problem in mpv on one FreeBSD system

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.
