Hello,
I am currently running a Yamaha rx-a1050 receiver for my zone 1 surround sound with the zone 2 output connected to a Yamaha r-s201 receiver. I would like to replace the zone 2 r-s201 receiver with a sonos amp. I connected a Sonos amp temporarily to make sure it could power my zone 2 speakers and it worked great, EXCEPT when I went to “party mode” on the main rx-a1050 receiver I could not get the music to play in-sync between the 2 zones like i could with both Yamaha receivers. There was a 1 to 2 second lag. Any thoughts on how to correct this and play music in unison when I switch out zone 2 to a sonos amp?
