No audio on ati radeon 2600xt

Earlier I was given up the problem with lower screen split or shift and even ghostly image whenever litle fast moving object. So I bought Gigabyte 8600GT and wait it to come in sometimes next week. While waitng for new item arrive, I finally tried to switch the setting of my ATI 2600xt to higher resolution 1920x1080 to see my Sony 720p LCD 46" KDL46S2010 would be taken or not and it work perfectly.
The reason I didn't change my TV to 1920x1080 because I this LCD is 720P or 1360x768.
Just update
