I have an old model (2010) Macbook Pro...the kind that only transfers video but not audio through the hdmi cable. I have this tv: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5247576 With these terminals: Inputs Composite Component In HDMI RF Input Ethernet (LAN) DVI Audio In Outputs Optical Digital Audio Audio Output HDMI Ports 2 So I can get video with a mini-dvi to hdmi adaptor and hdmi cable, but I can't get sound. I didn't know what "in" and "out" meant when it came to terminals ( complete newbie at this!) so I tried an audio cable, an optical digital audio cable and a DVI Audio cable. The audio and optical digital audio didn't work becuse they're output terminals, but neither did the DVI Audio in! Am I doing something wrong? Is there no way to get sound from my Macbook Pro to this tv??? Any suggestions? Thank you!
