NUC 7 - iMac (Big Sur)
cabled Ethernet 5e network with two Netgear LAN switches
the culprit Express base is hard wired with fixed assigned IP (10.0.1.3, which shows correctly for a short time in Roon Audio page, then switches to a mysterious 169.254.118.155 - I guess the factory assigned) and is connected with Optical Tos link to the DAC Bryston BDA-3
System has been working reliably (apart the old Airplay issues not entirely solved, but definitely made bearable long ago, since I wired the connection to the incriminated Airport Express) until yesterday, when I received a new (brilliant) hi-fi furniture, and I re arranged all the equipment on it.
Today the Optical input coming from the Airport Express to my Bryston BDA-3 DAC has become unbearably stuttering.
From the Audio page in Roon settings I noticed that that Express base is listed under ‘Other network devices’, while the other Airplay devices are all under the more reassuring ‘ROON Tested’.
Please See screenshot:
Before I start to check on each LAN cable I painstakingly laid down yesterday, I’d like to know if this
is ok or it’s a clue to what’s going wrong.
PS: the other systems attached to other Express bases work ok.
