I’ve been testing out my new iFi Pro iDSD DAC and ran into a similar problem, which I disgustedly reported to iFI. Now, it seems as though it might be a Roon problem.
I know the OP uses ROCK, but I run Roon under Windows 10. I don’t use DSP, but the DAC upsamples to 702K. The other day I couldn’t decide what I wanted to listen to, which resulted me switching from a track recorded in aac to one in flac and back again.
Doing so caused the DAC to drop its USB connectivity. My SMS-200 could no longer discover it. Turning the DAC off/on resolved the problem.
Clearly my Chromecast Audio DAC is not nearly as sophisticated as yours. The only other option I have at this time is a Pi with a HiFiBerry Digi+ Pro feeding a Sony STR-DN1080 using a coax cable. The Sony is a 2018 model and presumably has a better DAC although still not as sophisticated as yours.
I did notice the Prine tracks played Lossless TIDAL FLAC 44.1kHz 16bit 2ch while the Jones tracks played as Low Quality TIDAL AAC 44.1kHz 24bit 2ch.
Not sure I helped much.
Thanks for the reference to the Glenn Jones album, not one I would have found on my own. It may be a Low Quality stream but it sound good and I’m enjoying listening to it.
I appreciate the information here. I’ve passed your information above along to the team so they can investigate further. If you see this behavior return please let me know and we can take a closer look.
