I’m having the same problem, server and bridge are both linux and the 571 update disabled all my zones and lost the settings. I restored a backup from a few days ago and it didn’t bring back my zones or DSP settings.
If I try to recreate my DSP settings I get “unexpected error communicating with audio device” and I have to disable DSP to get playback.
Also needed to activate and rename my two Ropieee bridges.
After inputting their old names, I could easily select respective DSP settings, that I’d saved during creation.
Also had to group zones again and select respective icons.
Piece of cake, took about three minutes.
Edit:
I do see on thinking about it, that it may get tiring for those unfortunate fortunate ones with full house installs and multiple DACs per endpoint…
It would have been much nicer and smarter, though, if all that happened automatically, since the information was there to begin with.
I had to re-enable, rename and set up my DSP, etc. settings again following the update to Roon Bridge on my Rpi. No big deal for me, but I imagine it is for those with complex settings that haven’t saved as a preset (which I was guilty of - lesson learnt).
It might depend on the endpoint configuration. Raspberry pi with attached dac hat wasn’t impacted. A second one which uses hdmi for output has been reset/lost the settings.
Thanks for the reports. I’ve mentioned this to the technical team and we’re looking into this issue, once we have an update we will let everyone know here. Thanks!
