I've been trying to get analog line out to work to headphones or powered speakers with the latest Mac Mini, but so far the best I've managed to achieve is to get the internal speaker to work.
Any suggestions for amixer set commands or .asoundrc entries to get this to work would be gratefully received.
Details below:
