I have an iMac (2020 3.3 GHz 6-Core Intel Core i5 - Monterey OS)
Internet speeds are over 100-200 mbps and I have Google nest wifi mesh WiFi
iMac → USB → Gustard X16 DAC → AVR
I have 1400 albums
I have had no issues and today, I joined Qobus with a 30 day trial and added it to Roon (I also have a paid subscription to Tidal).
I installed the Qobus app for Mac as well.
Everything was working OK and then I tried to play an album in Qobus on Roon and it froze. Not a sound. I thought it was Qobus, but when I tried to play the same album in Tidal or my library - it did the same thing.
Finally, I realized my DAC was no longer an option to output. It was gone. I went to Settings/Audio and it was gone there, also. I exited and restarted Roon and closed the Qobus App and same thing.
Then I rebooted the computer and restarted Roon and all was well again. My DAC was showing and when I played something it was fine.
I returned to the original Qobus album that froze and it played fine as well.
I might add that this has never happened before and I assume is related to Qobus. Note that I had everything working OK after I installed Qobus (I also had the Qobus open on the Mac) for maybe 30 minutes before Roon froze and I lost the DAC. And when I say “froze” it was only the playback. The rest of Roon was working.
