Hello all, Hope you can help. Trying to stream video and audio through mbp to LG hdtv. Have bought a mini displayport to hdmi and it works great, but without sound. I can get sound through 3.5mm to rca cable, but I have to switch to av channel on tv, thus swapping from hdmi...you can see what's happening.. audio or video, but not both. Is there a way to allow me to get both using the gear I have already? or do I have to buy this: http://www.microanvika.com/product.asp?TXT=INFO&PNO=TAD35500&ref=froogle&cam=TAD35500&key=77880 My macbook does not support digital audio via toslink cable, I believe apple stopped adding this on my macbook. Any help would be appreciated. p.s I have searched the forum, there are lots of posts about audio out, but I cannot get a definitive answer, or people are recommending toslink cables. Thanks. Matt.
