im connecting my sony vaio vgn-fw21l to my sense hdtv via hdmi cable. i am getting picture but no sound. this is very unsual as i have previously connected the laptop to the same tv WITH sound on numerous occasions (no probs watsoever). however over the last week i can no longer get sound...i just cant understand it. ive tried system restore but this didnt work. any ideas?

PS. ive done the usual -(control panel -sound-change to hdmi-set to default) etc. but this doesnt work as it says its all working properly (via the tests etc-though i cant hear anything).

Actually one thing i have noticed is that when selecting to put the HDMI output in the Sound window as my Default-i can do this-but i cant press APPLY. i can just OK it. the green tick does come up by the HDMI tho. im sure in the past i was able to apply it, but im not 100% sure i cud.

The Apply Button Probably Messed it up, Just clicking OK wont apply it, it just returns to default settings. Are you Administrator?

ive been scouring the net and i think it may have summin to do with my ATI HD 3470 card. however, i just cant understand why all of a sudden its stopped working. it used to be fine.i cant remember updating anything. windows does auto update from time to time, but could thath be it?
