No Sound

[Thomas George]

I just installed an Asus Xonar DSX pcie card. Alsamixer recognizes it 
and PulseAudio Volume Control show a strong signal level during playback 
but no sound from the speakers. The system works with the onboard Nvidia 
sound, no problems.

I assume the problem is a missing linux driver for the Xonar but I have 
seen claims that Xonar works out of the box on linux systems.

Does anyone have this working?

I am using Debian Stretch.
