Hi We set our KS8000 audio delay settings without a hitch when we first set up the SONOS sound system. All was well until the latest software update. We've been unable to get lip sync accurately matched. It's the same 'need a negative audio delay' issue that many people have. We have set Samsung TV audio delay to 0 and Sonos to 0. There is still a minimal delay and unfortunately I am one of those OCD type people that cannot unsee the dlay and I fixate on it....so frustrating! We've noticed that there is a different delay from channel to channel and I can't watch some channels any more as it's infuriating. Did you ever find a satisfactory solution? Maybe either TV or Home theatre systems manufacturers should come up with an inline processing unit with large memory and storage that will accurately sync both video and audio before outputting through TV and speakers.
