The video/audio sync is because they are sent as a single stream, where the multi-speaker sync is requiring a very different set of functionnality, including having the player's clock synchronized to a external clock provided by the controler (the bridge in that case), the player being able to play each packet at a precise moment as indicated by the controler (each packet comes with a playtime based on the above sync'd clock) and the player has to guarantee a constant delay on its D/A conversion queue. What I saw using ShairPort Windows (eg) is that the timing aspects are not taken into account (in fact, I was running test with that at the beginning and I thought all was fine, but when I moved to a real player, I realized that some of my timing information were wrong, but ShairPort Windows simply did not care) LMS 7.7.5 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.
