Kemper scene, distorted sound and self-healing.

    Last night I turned off my kemper, everything was normal. That's what happened when I opened the Kemper stage today. A sizzling sound. Like a blown speaker. It's a very weak sound. I checked all settings, everything is normal. When I turned the amp block off and on, the sound got even worse. I thought it was broken. I turned the Kemper off and on and everything was as before. So why did this happen? Will it happen again? what if it doesn't pass? I'm afraid.. Has anyone experienced something like this?

    I did not install any updates.

    In the last year, we experienced the same issue few times on both Stage Kemper-s in the band. Luckily boot time is pretty fast so it's not a show stopper. My Stage has OS 8.6 installed, not sure for the other unit. We didn't find it enough critical to investigate further. Will update to OS 9 soon, i hope issue is fixed ...
