Can you please post the ALC1200 HDEF entry in your DSDT?
He's probably using the same code as everyone else. It's very rare to see HDEF DSDT code with modifications for a specific sound device. Some people add code to inject make and model of the device so that it shows in System Profiler, but that's purely cosmetic.
There are two different versions of the DSDT HDEF device, one for nforce and one for Intel chipsets:http://www.projectos...findpost&p=3781
Make sure you're using the appropriate one according to motherboard chipset, and that you have Method DTGP somewhere in there as well.
