So so disheartened after spending half an hour meticulously detailing my problem only to lose the post when I tried to publish the thread cos I'd been automatically logged out. AAAAAAAAAAAAnyway I hooked my 2008 Mac Book Pro up to my Sony nsx-40gt1 tv via HDMI + DVI adaptor. My 2008 computer doesn't have DVI mini port. The picture/desktop appears on the TV no problem, but the audio only outputs from the laptop speakers. Do I need these cables: http://www.ebay.com/itm/Monster-Cab..._Accessories&hash=item3cbc568f30#ht_500wt_882 A guy on youtube located his TV though System Preferences>Sound>Output and then located his TV, which I have been unable to do.
