I had this issue and got it fixed after a lot of frustration.
I had to manually make a custom resolution of 1080p@60hz in the catalyst drivers. Then change the sound to sync in xbmc to be off. Then exit xbmc, restart it and reset it to to sync to the video. Then go to the system info (I use transparency, not sure if all skins support this), and check if it now lists the system running at 1080p@60hz. If it does not, then you need to choose a different audio sync method in the xbmc settings, exit and go back in till it says 60hz. As soon as it says it's running at 60hz, the audio works perfectly.
Prior to doing this I had 24hz setup in the amd driver which it autodetected for my tv even though it can run at 60hz (probably because that is standard HD frequency), but it messes up the audio sync when this happens. Force it to 60hz and you should be good to go (assuming your TV can support 60hz)
