Hi,
either by one of the last updates or by me while un-pulseaudio-fy
firefox (and removing pulseaudio afterwards) mpv is no longer willing
to play any sound.

(why it is accessing alsa here???)
Using for example zynaddsubfx (softsynth) via qjackctrl/jack I can
play sound.
Mpv does not show up in qjackctrl....
The situation does not change if doing anything of the above as root.
Mplayer plays sound...but fails to play the video instead.
Currently I dont know what the problem here.
If anyone has any idea...heartly welcome... :)
Cheers
Meino
