I have always had occasional drop outs with Roon but did not think much of it since I was also using Devialet Air which many have been complaining, so I just blamed it on Devialet.
I thought bypassing Devialet Air with the latest Roon would cure the problems but I am still getting dropouts quite consistently, averaging about one dropout per 10 minutes or so.
I also discovered that the dropouts are not confined to playing via the Devialet. I also listen to headphones via my Macbook Air Roon client with Audioquest Dragonfly, frequency of dropouts about the same.
Here is my configuration:
Network - CAT6 GIgabit Ethernet, 8 port Linksys/Cisco switch
Roon Core - Macmini with 8GB RAM, internal SSD drive and external Thunderbolt drives storing music. Library size is huge with 30-40,000 tracks, mix of PCM 44.1, hires and DSD files.
The Mac Mini is hard wired and on the same Ethernet network
I have not tried mounting the Dragonfly directly, the Mini is headless and I stow it away in a store room. I can try but it sometimes take a while for the break to start happening.
(BTW The dropout usually last for about 1-2 sec before it resumes)
I have noticed dropouts in both 16/44.1 PCM and higher res files.
Does the large library have impact on the performance?
Is there anything else I can do to debug? Such as CPU loading or Roon log. (I will need instructions on how to get a log dump.)
If that’s not configurable, I suggest this experiment: Shutdown your Mac Mini (running Roon Core) and (temporarily) move it to direct connect to the TP-Link switch, and directly connect your Roon endpoints to this switch as well. Let the music data flow from Roon Core to your Roon endpoints via the TP-Link switch only, not any Cisco switch.
