When I play live DJ music through a seperate set of speakers via XLR and I also connect the Dj mixer output to a Sonos connect via RCA, which feeds into th Sonos network with 7 connect amps wired up to in-ceiling speakers. The problem is that there is a significant delay when the audio is passed to the Sonos network. It's probably about 1/2 to 3/4 of a second delay, which makes it near impossible to mix correctly and stream the live mix around the house.
I also notice this delay when I have a TV connected to to the rca input of the Sonos, so it's not the mixer at fault. It's been this way since brand new and after man firmware updates.
Any tips? is this a hardware limitation due to running over wifi and processing, or is this something which can be rectified with a firmware update?
