I have a USB Dac hooked up to my Pi Zero running Jessie (It’s a Daffodil US01 USB Sound Card 7.1 Channel / Plug and Play / Microphone In and 3.5mm Speaker Out. ‘alas-info’ lists it as: USB-Audio - C-Media USB Headphone Set).

It works great when I do: aplay /usr/share/sounds/alsa/Front\_Center.wav -D sysdefault:CARD=Set

It also works great if I do airplay streaming to it.

It does NOT work however in Mopidy.  
When I try and play my music I get no sound.

I have installed gstreamer0.10-alsa as well as Mopidy-ALSAMixer.  
I don’t get any errors or warnings in the logs.

If I go into alsamixer the USB sound card is set as the main card, and if I run ‘mixer controls’ I get:  
Simple mixer control ‘Headphone’,0  
Simple mixer control ‘Mic’,0  
Simple mixer control ‘Auto Gain Control’,0

My config /etc/mopidy/mopidy.conf:

[audio]  
output = alsasink  
mixer = alsamixer

[alsamixer]  
card = 1  
control = Headphone

Again, no errors or warnings in either the mopidy log file or the main messages log file.  
Anyone have any ideas or suggestions?
