I may be able to do that. But I have to reproduce the situation again.
Roon has been working for some days now. The day after the occurance, I restarted and everything worked.
The ‘no devices’ issue is different from the not playing issue, by the way. They seem independent.
The not playing issue will make Roon cycle through the tracks, attempting to play them. But there will be no sound. It doesn’t matter which album I play.
I know that it will occur after I switch soundcards in Windows. I sometimes switch to the Yamaha CX-A5200 to play a movie. I somehow cannot keep the windows settings there for Roon to play via the ecdesigns Fractal dac.
