Unpleasant Background Distortion since upgrade to 8.6 Beta

Hello

I' m using the Kemper Profiler Stage via SPDIF to Focusrite Audio Interface. Since I've upgrade to 8.6beta I experience very annoying background distortion. I sounds like something is vibrating on the desktop but that's the case All other devices sound the same.

Was there a big change in the firmware? Is there an easy way to downgrade using the Rig Manager?

Regards

Andreas

Ok, kind of strange, that nobody seems to have the same problem.

Just in case somebody is interested. Downgrade to 8.58 solved the problem and there's a "revert os" function in the RigManager.
