I am losing the will to live now as I have tried various recommended audio extractor boxes and am still having a audio delay through my speaker system. 

I am trying to use a projector with my Sonos system but my audio is way behind and cant seem to find anything to sort this issue.

I did have a little success with connecting my amp to a sky multi box (through the ARC HDMI) however this isn't very practical but at least it worked. I am really hoping someone can help as after spending a considerable amount on the amp plus ceiling speakers I would love to get a solution.
