I am trying to get my digital output to work. In alsamixer my S/PDIF is on but no frame around and I can't regulate the volume. Is it maby not activated or is my digital input on and output of?
Specs:
Ubuntu 16.04 (Linux Mint)
Asus Xonar DG (soundcard)
Here are some screenshots of aslamixer and audio manager:
Would be nice, if someone can help me. Thanks
