HI ! I follow this guide for my P5K-E Wifi , and I am using dsdt patch + AD1988b.Fix.kext for the sound.
I read a new thread for 5.1 sound at this link.

He said he has 5.1 sound now, so I tried his guide at my computer.
I know my computer has 3 out in system configuration,and each out has different speaker connection.One is main speaker (L+R), second one is center speaker,and the other one is subwooper.
I tried make new Aggregate Device corresponding to the 3 Line outs in Audio Midi Setup, but I have no sound.
If anybody has soulition of this, then we can have the 5.1 sound in P5K-E too.
