I suspect OP's problem isn't with Roon. I use a Roon Nucleus and have never experienced the problem OP complains about, nor did I experience it when I ran Roon on my iMac. I use Qobuz, Tidal, and files I ripped from CDs.
To ROON or not to ROON?
I use Roon fed by Qobuz. Roon stalls and locks up of I do a lot of music surfing. I have to Control -> Alt -> Delete and stop the Roon Server then reboot. Surely there has to be a better product out there! Any advice?
