[HELP] Configure Mopidy to use ALSA USB Soundcard

General
1

Hi,

totally new to Mopidy, I try to set the Mopidy’s configuration file on my Ubuntu to use the SPDIF output of my USB card with ALSA.
So if I try gst-launch-1.0 audiotestsrc ! audioresample ! alsasink I can hear the sound through the HDMI but I don’t know what to write in the mopidy.conf file in order to use the USB -> SPDIF output
The output of aplay -L :

So what parameter should I use with audio/ output = alsasink parameter in order to select the USB -> SPDIF ?

Thank you !

i have similar issue, Mopidy can play on my on-board sound card device, but when i set the alsa default to USB DAC, Mopdiy cannot play on it.
below is the warning i got.
2019-01-03 11:03:48,519 WARNING [1642:Audio-2] mopidy.audio.actor: Setting GStreamer state to GST_STATE_PLAYING failed

in mopidy.conf
i just set the audio/output to alsasink

what i am missing?
could you share your fix?
thanks!

You can name your device and explicitly set it as per here. Or specify the device using the syntax device=hw:X,Y where X and Y can be found for your device using aplay -l.

Or you could take a look at using gst-launch-1.0 as per our documentation to debug what’s going on. i.e.

gst-launch-1.0 audiotestsrc ! audioresample ! alsasink device=hw:1,0

Or you could provide a better explanation of exactly what you are doing as this is much too vague.

  • Output of cat /etc/asound.conf
  • Output of sudo mopidyctl config
