Devialet AIR sound settings (Windows)

[ogs]

Possibly because relatively few use Devialet's virtual sound card driver here at DC - for the very same reasons you notice, it's not reliable. If you use Roon the built-in AIR is much more reliable. Other than that a Raspberry 3 or 4 with a SPDIF HAT or a 4 if you want to use USB is the way to go for a low priced high quality streamer.
