After using ropieee happily for years desaster struck last week (maybe earlier).
I have to ropieees in my living room, feeding speakers and phones. As I spend most of my time on the desk, these are not used often, When I tried three days ago they were not available in roons audio settings.
Both show up on the network though and can be configured. A PC at the same location works nicely as backup roon bridge.
Couple of things to look into:
Have you tried rebooting the network and roon server?
Do they show up on the Settings/about page in Roon?
Do they have the same “192.XXX.XX” (subnet) as the Roon server?
Do they show up in Settings/Audio and just need to be enabled?
What DAC(s) are you using? USB or HAT? and are they/it powered on and ready?
What version RPis are they?
Also, the latest beta of RoPieee is 2024.03 (1421) [beta] for Rpi4 and 2024.03 (1420) [beta] for RPi 3s, so you may need to update again? Not that that is the issue?? but worth noting.
