I have finally got around to connecting my intel-based iMac to my stereo amp and speakers.

I bought a 3.5mm stereo jack to 2xRCA/Phono and plugged the stereo RCAs straight into my amp - however the sound is only coming through in mono.

I have checked my settings to make sure that my mac is sending sound in stereo and indeed it is. So I'm a bit baffled to be honest. I have check that my stereo sends stereo sound in other modes other than aux and it does. I have also checked that other aux devices (my turntables) work in stereo; they work perfectly. When I plug headphones into the jack socket on the back of the iMac the sound comes through in stereo!!

I like to consider myself fairly tech-savvy but this has completely beaten me! Any ideas?

The only thing I can think of is that the 3.5mm jack socket on the back of my iMac has the contacts in 2 different places to differentiate between headphones and speaker devices - but I can't find any instruction of this and it seems wholly pointless for Apple to do this. Anybody wiser than I am about this I would appreciate some help


P.S - Also I have checked the cable from my MP3 player to my amp and works fine in stereo sound
