Could this error-message relate more to the Bluesound firmware than to Roon itself as pointed out at?:
This happens while been using BluOS and then switching to Roon. Then Roon will not get access as supposed to.
I thought thought that this has to do with the grouping in BluOS and therefore not accessible from Roon to group once again but it appears to be very random.
Grouping works in Roon but in some cases just one of my 4 Powernodes rejects with this message. I have also ungrouped in BluOS but still same issue remains.
I think I made an reset in the router once and then it worked again but not very useful to do everytime using Roon.
Play a song via spotify to one of the bluesound endpoints: kitchen
2, Group with another bluesound endpoint via the bluesound app; in my case: A powernode2 is added to/grouped to the kitchen (pulse mini) which was the original endpoint selected in Spotify.
3, Pause the music via the spotify app.
4, Ungroup from the bluesound app
5, The select Powernode2 in the office via the Roon app to play something
6, Get the error message: Transport: failed to select Roon as the current source
7, You have to reboot the bluesound endpoint to get roon to play music to that device.
This bug can be reproduced each time by following the steps above. I have reproduced it twice now.

Also in support package support_e3cff966-1965-4e95-9322-0cdab48c413e_29FE7615-DC6C-4BBE-8A68-75EB8819A257 from 9:21PM you’ll find the same.
For me in short terms, once grouped in BluOS i cannot group properly in Roon anymore.
However if only using Roon it works with grouping. It is like BluOS occupies the endpoints somehow once played the first time and will not give access to Roon.
Just awaiting a reply from @support because it is not clear if this should be posted to bluesound; mind you, I do now believe that Roon and Bluesound have established a liaison for this forum. Stops the double posting on each of their respective forums too, I guess.
Anyhow. Looks like my post and yours should be merged so can @support do this too?
