Possible? Send Audio to receiver 75 milliseconds before video to screen

I’m possibly looking to pass the audio from my AppleTV2 to a Sonos zone player and then pipe the audio to other players around the house / to other speakers in the room wirelessly, according to Sonos, there will be a 75 millisecond delay between the receipt of the audo source on line in and it being played by the other wireless speakers.

I was wondering whether it would be possible to set a global option in ATV Flash black, that would allow the audio to be sent to the Sonos players 75 milliseconds before the video is sent to the TV, which would help the video and audio to come out in sync, I know that this is possible with applications such as VLC, but haven’t seen anywhere in ATV flash black where I can adjust this.

Can anyone help?
