Hi, |

either by one of the last updates or by me while un-pulseaudio-fy |
4 |
firefox (and removing pulseaudio afterwards) mpv is no longer willing |
5 |
to play any sound. |

(why it is accessing alsa here???) |
76 |
|
77 |
|
78 |
Using for example zynaddsubfx (softsynth) via qjackctrl/jack I can |
79 |
play sound. |
80 |
Mpv does not show up in qjackctrl.... |
81 |
|
82 |
The situation does not change if doing anything of the above as root. |
83 |
|
84 |
Mplayer plays sound...but fails to play the video instead. |
85 |
|
86 |
Currently I dont know what the problem here. |
87 |
|
88 |
If anyone has any idea...heartly welcome... :) |
