I’ve tried one more thing, still without success - I removed the Core installation on ZENTV and installed it on ZENMESTO (the second machine).
Now even with just the Core, there are no audio devices found. No networking involved, just trying to play on the same machine that has Core installed.
My device manager shows a bunch of audio devices and audio works fine in Windows (my main soundcard is RME Fireface UCX II with rock solid Windows drivers). But Roon doesn’t see any audio devices … I tried reinstalling, rebooting etc. What can I do to fix this?
(I also tried disabling a bunch of audio devices and just leaving one enabled etc. - no help)
I’ve tracked this down to my local development server (Laragon) running on port 80 - which is standard for any kind of development environment. After stopping the nginx service on port 80, Audio devices start showing up again. I’ll ask about bypassing that in a new topic.
