    I've read several threads where people have been having trouble with this, but nothing has been resolved so far, maybe someone can help me out?
    I've got a 2ghz core duo mac mini running OS 10.6.4.
    I used to be able to stream digital output from it, but I cant anymore & it's driving me around the bend.

    I have tried new cables, different combinations of sources of audio, cables, inputs on my AV receiver and everything is in good working order apart from the digital out on my mac. It will play analogue stereo fine, it will play from the built-in speakers, but it will not play the optical digital stream.

    As I said before, it used to do this fine, until one day it just stopped working, it kind of 'faded out' and never came back. The light still shines when the toslink cable is plugged in and the output switches to digital in system prefs, but nothing is being received by the AV receiver.

    It seems that others have had similar problems, but has anyone found any solutions?

    Any help would be much appreciated, cheers.

    I never had this problem and I really hope I never will, but since you mentioned that it faded out maybe you should clean it, but be careful not to damage the optical projector.

    Try searching on the web or on Apple's Support forums for more info.

    And Good luck hope it will get fixed.

    Just wild guesses, but I'd try rapidly inserting/removing the plug a few times. Also I'd try a compressed air blast into the port.
