So I just bought a brand new Mac Mini to use with my Samsung LN-R408D LCD TV. I hooked it up using mini DVI to HDMI for video, which works great. I also hooked up a TOS to Optical cable from the headphone jack in the Mini to the optical out in my TV. My TV does not have an optical in port. I'm getting absolutely no sound through the TV speakers. I also tried hooking up a male to male stereo cable from the headphone jack on the mini to the PC audio in, in my TV with no luck. I've attached a shot of the back of my TV from the instruction booklet. Does anybody have any suggestions? I'm at my wits end here. Would that new cable at Monoprice work, the one with the USB and miniDVI to HDMI port work for me? Has anybody had any experience with it? Any help would be greatly appreciated!
