Roon message error: "Audio device in use"

[ogs]

When I had the 240/250 I preferred to use the AES/EBU input. At some point I got a Mutec. Better sound than any other option with microRendu->Mutec->Devialet. And the stability using Roon RAAT to microRendu was fabulous.
It is very 'clean' to use AIR (or RAAT on the CI models) to the Devialet. In most cases the Devialet is networked anyway, so why not? Your last chance with AIR is to try wifi (you may have tried this already).
