Hi Eric, thanks for following up.
I placed the topic in #support as I wasn’t really sure where to put it - but I was really wondering whether anyone had experienced any network issues after updating to 10.11 - and not specifically with Roon.
But I should list this anyway:
Mac mini, late 2012, 2.5ghz i5, 8gb ram
OS X 10.11.6
Music and OS local SSD
mac minimal apps installed but does have carbon copy cloner and a few other utilities. iTunes runs in the bg (for music import only).
Raspberry pi 2, RoonBridge, raspbian, hifiberry DAC plus (phone jack version)
Raspberry pi3, Dietpi RoonBridge, iqaudio DAC
Microrendu into Devialet 200.
All hard-wired cat5e into gigabit switch (little netgear 308), and onto cable router/modem.
Very occasional stutter on the hifiberry zone, most likely playing Tidal, and most likely at least one other zone playing something. Stutters are short, and often go away after a minute or so. Once or twice have persisted and restarting RoonServer machine sorted it. I had one or two stutters on the rendu but that was a one-off.
Last couple days been totally stable again.
I’m assuming it’s something background in 10.11 or something weird with the upgrade. It makes me nervous though as in a year or more no stutters with Roon ever (except one when I left the wifi and Ethernet active at the same time on the core).
It could be anything I know - from the router, Tidal servers, internet connection, the pi, the Mac, and endless other things. That’s why I wondered if anyone else had experienced it before I started trouble-shooting or reverting back to 10.10.
I had run a CAD optimisation script on the Mac with 10.10, so some of that’s probably ruined now, or maybe has left a mess.
Thinking about it if I can find the time I might just do a fresh install and see what happens then.
(Ps it would be great if Roon could extract all the info about the setup to paste here, so we could just fill in the blanks…)
