Hi I am new to the forums. I have a macbook pro late 2010 model. I purchased a mini display port to hdmi adapter and hooked that to my vizio l37 tv and the picture worked fine but the audio wont work. I have searched the forums and cant find an answer. I saw the guide to hooking my mac to a display and my adapter is compliant with the new macbooks for audio through hdmi. There are reviews for the cable from people saying the audio works fine when they go into system preferences then sound and select the tv for sound but mine will not recognize my tv for sound. Ive read some people change their tv from digital to analog sound but my only option is from digitalhd to dvi which i tried and it did not work. I hooked it up with a 3.5 mm to rca jack to my preamp for my surround sound and that works but i would much rather just use the hdmi instead of having all those cables. I realize that the audio will only be stereo and not dolby surround but that is fine i would just like to get the audio working through hdmi. Thanks
