I have a serious and annoying bug from some time. 

When I switch on my TV, connected to an Amp, the Amp and all active speakers in my system sets their volume to 100% !

It is obviously extremely annoying. 

Before, switching on the TV would have no effect on other speakers and the Amp would detach itself from any group. This is the intented behavior.

I suspect this is a bug from lastest software release since nothing changed in my setup.

I can’t comment on the volume issue, but check that you have TV Autoplay and Ungroup on Autoplay enabled. Toggling them off and on might help too.

Next to grouped autoplay the level 100 volume issue sound quite strange to me. 
I strongly recommend to contact Sonos support, send diagnostics and let them take a closer look at this.
