Optical Audio Not Working
Hi my dear Apple Community,
First of all, I apologize if there are already discussions on this topic but I have tried to search for a current discussion without any success.
So here is my problem, I updated my 2010 Macbook Pro to Mountain Lion this summer and it had been working perfectly fine until the 10.8.2 update about a week ago. My optical audio will not work anymore. The port still detects an optical cable and switches to optical audio (the end of my cable is red and lit up) but when I plug it into my amplifier it does not work.
I can confirm that the amplifier does work as it works with a 2011 Macbook Pro that is still running OS X Snow Leopard, using the same cable.
Therefore I can say with absolute certainity that this is software based.
I have tried to switch to encoded audio in the Audio MIDI setup application without luck, my Mac will not even output any sound in encoded audio, iTunes won't even start playing a song. I have tried to swicth from 24 bit to 16 bit audio integer as well as lowering my sample rate to 44.1KHz and 38KHz.
I would like to know if there is anybody else in my situation and if there is a workaround to this problem. I'll do whatever it takes to make the sound work because right now I cannot watch HD Movies with 5.1 sound, nor can I listen to music in my living room anymore.
Thanks a lot for your help and support !
Cheers.
Scott Gauthreaux.
