Hello all
I need help. I've looked everywhere and can't get this to work. I have a 21" iMac that I purchased earlier this spring. I have a new Onkyo receiver that has optical inputs for digital sound. I have a 6ft Toslink to Mini Toslink Cable plugged into the headphone jack on the back of my iMac and it goes into the optical input in the back of my receiver. The red light comes on on the cable when I plug it into the iMac which tells me that the digital sound is working.
However, when I play anything I only get 2 channel stereo. iTunes HD downloaded movies, DVD movies, ripped DVD movies, everything. Only 2 channel.
I have downloaded Perian and have tried it with Dolby Pro Logic, Dolby Pro Logic II and Multi-Channel Output. I've gone under my Audio Devices in Utilities and changed the format to 48000.0 hz. I've also tried 2 channel 24bit and 2 channel 16bit.
No matter what I do I still ONLY get 2 channel output. This is very frustrating. This is about the only thing that has given me problems since switching from a PC. I had no problem getting 5.1 surround on my WIN7 PC. I would think that it would be easy on the iMac (everything else has been easy).
My receiver has 5 HDMI inputs and 2 Optical inputs and has NO problems spitting out 5.1 (can go up to 7.1, but I don't have anything that has that yet) surround sound from our DVD player and Cable TV box.
What is going on here? Am I doing anything wrong? or should I head to the Apple store and see what they say?
I'm at a complete loss.
