Having the same issue. Playback dropping out within a few seconds when routing to a Mac Pro running Roon 1.6 (Build 416). Problem does not occur when routed to the system output, or when playing the Tidal desktop app.
So we can better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
You mentioned that this doesn’t occur when playing to System Output. Can you confirm what endpoint it does occur with and how it’s connected?
Remote machine: Mac Pro (2013 trashcan), macOS 10.14.4, Roon v1.6 (build 416)
Both machines connected via Airport Extreme over wifi.
Audio output routed from Mac Pro to a Metric Halo ULN-8 via MHLink over cat-5e cable.
Music library is stored on an external HD connected to the Macbook Pro via USB. 14994 tracks. The problems I’m experiencing, however, occur only with Tidal when using the above routing configuration. Often the error occurs when starting playback for the first time when bringing the machines out of sleep. After stopping and restarting playback, the problem resolves. Other times, it seems to occur at random, so I’m not sure this is useful info.
The type of connection seems to make little difference. In either case–wifi or ethernet–when I get the errors in Roon, I do not get the same errors with the Tidal application.
My apologies for the slow responses. The problem is intermittent, so I have to wait for an opportunity when the issue is repeatable, then quickly switch connection types.
