No sound from autoaudiosink

[jbmestelan]

Hello,

When setting in config:

[audio]
output = autoaudiosink

I can hear no sound from mopidy.
(Other apps can use the soundcard alright, with hearable volume)

I have tested that
gst-launch-0.10 audiotestsrc ! autoaudiosink
plays a beep alright.

mpc play causes this log in mopidy:

WARNING GStreamer warning: gst-resource-error-quark: Could not open audio device for playback. (6)
WARNING GStreamer warning: gst-stream-error-quark: No volume control found (3)

Could you suggest a way for me to investigate this?

Thank you.

Is the user running mopidy in the audio group? The no volume control is a red herring, which is fixed in the next release.

Is the user running mopidy in the audio group?
Yes. I run mopidy as my regular user.

mpc volume
volume:100%

For the record, and in case it might help, I am writing this because I tried to change my config, due to #1499

If you want to compare with Mopidy 2.0, you need to test with GStreamer 1.x, not 0.10:

gst-launch-1.0 audiotestsrc ! autoaudiosink

Thank you very much.
This command prints the log below, and plays no sound.
After installing gstreamer1.0-alsa, the sound plays OK

% gst-launch-1.0 audiotestsrc ! autoaudiosink

Not sure why the first log mentions Jack server, but as for me, the problem is resolved.

Thanks for mopidy.

jacksink is often preferred by autoaudiosink when alsasink isn't present. Once you have alsasink that is used instead and the jack warning disappears.
