Mopidy with Gstreamer does not play a single stream or file

I just installed Mopidy on Ubuntu 14.04 on my Wandboard.

Avery time I’m starting an mp3, internet stream, Spotify or Dirble stream, I’m getting the following error:

2015-09-29 11:56:49,458 WARNING [1732:MainThread] Element doesn’t implement handling of this stream. Please file a bug.

No matter what file I want to play. It’s always the same error.
If I play the internet radio station with Gstreamer directly with this command:
playback is working fine.

All the streams I’m trying to play are working on my Raspberry.

Do you have a suggestion I could try?


I have the same problem on my Raspberry…

Gst-play-1.0 is gstreamer 1.0 while mopidy uses gstreamer 0.10 so you
probably want to use the correct version when checking direct playback.
Once you do that you can use the gstreamer debug messages to see what’s
going on, there is something in the Mopidy troubleshooting docs about doing

At the end I was able to solve the problem.

The stream was always played on the wrong sound device. No matter what I
changed. I solved it by blacklisting the kernel modules of the sound
devices I did not want to use.
The warning message seem not to be related to the issue. I still see this
warning but everything is working now.


Can you give me the configuration of mopidy on your Rpi?

I’m not using a Raspberry Pi, but a Wandboard.

Did you try to change the default audio output via raspi-config?

The following config works for me:

cache_dir = /var/cache/mopidy
config_dir = /etc/mopidy
data_dir = /var/lib/mopidy

config_file = /etc/mopidy/logging.conf
debug_file = /var/log/mopidy/mopidy-debug.log

mixer = alsamixer
mixer_volume =
output = alsasink

enabled = true
