Jon,
I d/l the beta, and upgraded MC to 11.0.299 running UPnP server 1.0.32 -- it does not solve the problem.
This behavior is repeatable but not consistent. Let me explain:
1) Download new beta firmware, erase, flash, etc.
2) Download new 11.0.299 MC, install, start UPnP server
On Roku:
3) Connect <OK>
4) Browse <OK>
5) Audio -> now a msg pops on Roku saying, "Waiting for Response"...after about 60 seconds, it comes back. If I choose Artist, it will fail. If I simply scroll down and select a genre, I can stream and play ok.
Steps 1-5 worked a couple times with similar results.
Today I tried the same, and MC11 crashed with an exception (this is typical of what would happen consistently before)
I am totally bummed out. I actually ordered the HomePod from MacSense b/c I can get the firmware and perhaps I can solve any issues with that myself. I'm still waiting / hoping that I can get MC11 to work consistently with the Roku.
Recall last time when you had me clear the Registry entry in Windows -- and that seemed to intermittently fix the issue, but it requires a complete re-import of my library. Is there some clue to success in that nugget of information?
Regards,
Davis
