During the evening I regularly listen to Roon + Tidal over the above setup. I’d estimate that every 10-15minutes I’ll hear a brief pause or hiccup for a fraction of a second in the audio stream- sorta like if a buffer ran out. It doesn’t seem to be an issue with certain tracks, as if I go back in the track the problem won’t repeat itself.
There shouldn’t be any network congestion as nobody else in the house is on the internet, watching Netflix or anything like that.
I can’t say if it happens only with Tidal or if it happens with my FLAC files as well- as Roon seems to only want to play Tidal when both exist.
Edit: Last night I specifically played a ripped album and it happened twice. Once on the 1st song and again on the 5th. Hence the problem is not limited to just Tidal and doesn’t seem to be internet streaming/congestion related.
