Hi all, I've done as about as much research as I can but haven't found a solution. Suddenly the headphone socket on my iMac G5 has stopped working. It is not recognised in system pref's / sound as it just says 'built in speakers'. I have tried the following to no avail: Trying 3 different headphones, Wiggling the 3 different headphones in the socket, Restarting, Cold restarting, Resetting the PRAM by Opt + Cmd + P + R for two chimes for three chimes, three times, Reinstalling Leopard. Installing software updates. I'm on an intel based iMac and it's not under warranty any more. 8 hours a day without music is going to make my life frankly miserable. Any more advice from anyone wishing to make my week / year? Thanks all.
