[gentoo-user] mpv: no sound anymore...?

[tuxic]

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... :)

I don't have any particularly concrete ideas because the error log isn't
very descriptive, but I have several things you can try that will give
us more info/may help pinpoint the issue.

You might want to post the contents of your /etc/asound.conf and your
~/.asoundrc as well as maybe checking the contents of /usr/share/alsa if
there's anything still referencing pulseaudio in there. Maybe also a
qcheck media-libs/alsa-lib to check if any of the default config files
have any changes in them (you can also diff the output of qlist alsa-lib
and find /usr/share/alsa).

You might also want to check your mpv.conf if you have change any of the
audio settings there.

You can try running mpv in verbose mode (-v) to see if that prints any
more relevant information and also try using any of the other (alsa)
audio-devices listed by --audio-device=help. You could also try setting
--audio-samplerate=48k and try enabling/disabling alsa resampling with
--alsa-resample=yes/no.

mpv's verbose mode will probably give more info as to why it's trying to
open alsa, but I don't know enough about jack to give any useful ideas
here.

What samplerate does that generate sound at? 48k or 44.1k?

I'd start by running 'alsactl init' to (re)initialise alsa and see if it 
reports any errors.
