I’m finding Audirvana Studio via UPnP to RPi4 running RoPieeeXL to be a little problematic. I never have problems with Roon RAAT. I think it might be because the RPi4 runs hotter with UPnP and Audirvana Studio than with RAAT and Roon.
EDIT: I think I misspoke about this. I’ve been streaming Tidal and Qobuz for 2:14 using Audirvana Studio, RPi4, ,RoPieeeXL, and UPnP and temps have only gone from 115.1 to 117.8.
