Great guide thanks. Hopefully there'll be a "cleaner" solution eventually... VoodooHDA is looking promising.

this is what happens when playing stereo, os x doesn't have an integrated speaker fill option, sound is only passed to the correct discrete channel specified in the source media. did you try something such as a video file with ac3 5.1 audio, with perian set to multi-channel output? also, apple dvd player with output 5.1 thru spdif (digital out) ONLY have to use VLC for multi-channel instead.

it's normal for a spdif output not to have a software volume control isn't it? because the outputs aren't being handled in software, simply being passed-thru digitally.

I use 3 line-outs as an aggregate for 5.1, and still get no volume control (ALC888) i think this is a limitation of the aggregate devices.
But I came up with a little fix & i guess anyone else with this problem can use these steps to try to force software volume control:
1) Make sure each output you intend to use is set to full volume in sound preferences.
2) Set the aggregate device up as usual & assign speakers in Audio midi setup.
3) Using Soundflowerbed, set the 6 channels of the aggregate device to the first 6 of Soundflower16ch.
4) Select Soundflower16ch as default output & configure speakers for multichannel output in Audio midi setup.
5) Software volume control for your 5.1 enabled system

hope this helps someone...
