Description Of Issue
When streaming from Qobuz (any resolution), the intense network activity from caching causing the CPU of the Synology to spike leading to dropouts (See logs below). Once cached (15-30s), playback proceeds flawlessly. This only happens with Qobuz. Local files up to 192/24 play fine start to finish.
Is there a way to specify some kind of limit on how aggressively Roon caches from Qobuz?
Update: I’m actually seeing this happen now throughout normal playback, not just during caching. Jumped the gun a bit on a theory / diagnosis, I think. Title updated.
