GStreamer fails to find a supported audio sink about mopidy HOT 9 CLOSED

If you have working ALSA, try forcing Mopidy to use ALSA instead of the autodetected OSS4 by setting:

GSTREAMER_AUDIO_SINK = u'alsasink'

in ~/.mopidy/settings.py.

from mopidy.

that gives the following error when starting mopidy:

These are not really Mopidy errors, but GStreamer errors.

Try finding a GStreamer combination that works on your machine through testing different sinks ala:

# Mopidy uses autoaudiosink per default
# If this works, Mopidy needs no custom configuration
gst-launch-0.10 audiotestsrc ! autoaudiosink

# Using ALSA directly:
gst-launch-0.10 audiotestsrc ! alsasink

You can find all currently installed GStreamer sources/sinks using:

gst-inspect-0.10

from mopidy.

Thanks.
Installing gstreamer0.10-alsa made the difference. Maybe good to mention it in the mopidy dependencies for the alsa mixer.
To run gst-inspect-0.10 I needed to install gstreamer0.10-tools. Maybe also good to mention that when you discuss gst-inspect at the bottom of the gstreamer installation page.
Many thanks!

How GStreamer is packages will vary from distro to distro, but I'll add some kind of note regarding this.

Glad that you got it working :-)

The develop branch docs was updated in commit 7743fa3 with tips on how to test the GStreamer installation.

Sorry to resurrect such an old issue but I just hit this with the latest xbian release (Beta 2). When you do gst-launch-0.10 audiotestsrc ! autoaudiosink you get :

Setting pipeline to PAUSED ...
FATAL: cannot locate cpu MHz in /proc/cpuinfo

I think this is because it's got a weird kernel (Linux xbian 3.12.7+ #5) that doesn't include a bogomips field in /proc/cpuinfo and JACK is getting screwed up.

Anyway, my point is that since the raspberry pi installation guide suggests setting output = alsasink it should also suggest installing gstreamer0.10-alsa too.

That's a too good point to hide in such an old bug, @kingosticks ;-)

Fixed in 9db9def.

I do try my best! Thanks for fixing.
