*Description Of Issue
Room remotes see files in my database, and ROCK can be operated via web browser, but “Failed to open the audio device” appears whenever I try to play something. 2+ years with same setup and no issue before. Tried restarting Roon server software, reinstalling OS, and swapping hard drive library with another. Still fails to open.
Thank you for your replies. I figured out what causes the “Failure to connect…” error message. It’s not the cable, an HDMI from NUC to AV preamp/tuner, which works fine.
I forgot to mention that I have a Roon-Ready HiFiBerry DAC+, to extend my Roon into a guest room, for occasional use. When I disabled the HiFiBerry, the main setup worked fine. I’ll have to look into why the HiFiBerry no longer connects — maybe a software-update issue.
The WiFi operated the HiFiBerry, and the wired connection operated the NUC. Until the other day, when the HiFiBerry stopped connecting, and prevented the NUC from connecting, too. disabling the HIFiBerry re-enabled the NUC.
You assumed a USB connection. There is no USB connection: the NUC connects to the AV via HDMI.
Resetting did not work, but I was able to fix the problem by purchasing a new microSD card, downloading the latest HiFiBerry version, and restarting the system. It’s possible that the old SD card failed, since I wasn’t able to erase it and rewrite it with the image of the new software.
The guy at the store, where I bought the new SD card, was wearing a gas mask like this one, to avoid COVID-19, so it felt like an adventure.
