Roon "Lost control of audio device"?

All of a sudden for the past couple of weeks, I can’t get through 2 minutes of a song without receiving an error stating, “Roon lost control of the audio device.” I use a Spectrum modem and router. Spectrum  replaced my router, but I continue to receive the same error. Sometimes I hear what sounds like static coming through my speakers, right before the error pops up and the music stops. I’ve tried resetting my Antipodes S40 music server and my Chord English Electric 8 Switch. How do I correct the issue, because I can’t listen to music? Can anyone recommend a good router/modem?
