I have a problem with this receiver. The sound cuts out at irregular intervals as if someone were pressing the mute button for 1 second.

By the way, I'd also take a look at the TX-NR7100. It costs a bit more, but it's worth it. Sounds much better!

If the question of being able to connect sonos to the onkyo, yes you can do it via sonos port and connect *sold separately

It does have a 2nd zone on the wire output that can be connected via speaker output
