Hi,
I moved my Audirvana Studio from Linux to Mac this weekend and since, it is almost impossible to find my iFi Zen Stream in the UPNP list. Meanwhile, in the log, I can see:
2026-04-13 10:31:05.937 [error]: UPnP select device: can’t find the device iFi audio iFi audio with UID: uuid:48e75bf1-ed45-6dbf-cc31-32df7bf44f21
No issue with my previous linux installation.
Regards
Vivien
