It is clipping like mad and causing serious distortion.
This needs to be sorted as it could cause serious damage to people speakers if they don't notice.
I have set it to variable for the time being, but obviously not ideal.

If you're experiencing an issue with audio issues on your CONNECT after updating to 6.0 can you check that the issue goes away if you turn the volume on the CONNECT down to 95% instead of 100%? If your CONNECT was set to Fixed volume you'll need to change that to Variable under Settings > Room Settings.
If you find that this fixes the issue, we are working on a resolution for this issue in the latest version of the Sonos public beta. You can join the beta by following the directions on this page. After you're signed up for the beta, go ahead and update your system and let us know how it goes. Once the beta is over the fix will roll into the next version of the Sonos software to be released further down the road.
Let us know how it goes, and if you do still have any audio trouble with your CONNECT, it'd be best to give us a call and work with our team live.
