Hi Andy, you are not alone. I am facing the same thing. I do see one common item though.
Bluesound / NAD.
I am only getting this behavior on my Node2 in my Home Office. In the living room I am using a Lumin D2 and there all works fine.
Also I think this is only when using a streaming account, like Qobuz in my case. Need to check if this also happens when I play local files.
This is already over a year and I kinda got used to it, so never really bothered. Except now with COVID and home office, I am using the Node2 more often and it gets annoying.
My details for roon if needed:
Core Machine (Operating system/System info/roon build number)
Server: Windows 10 - i7 7700 - 8GB Ram roon 1.8 (build 764), but also applies to earlier versions
Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
All hardwired CAT 5 or CAT 6, internet connection 250mbps. Router Deco M9 plus, WiFi not used for audio, only for networked devices like iPad.
Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
Lumin D2 (hardwired Ethernet, analog connection XLR) Node 2 (hardwired Ethernet, analog connection cinch).
