[SOLVED] Can't extract DSDT for audio fix - No nodes found

I got El Capitan running on my system pretty easily, but one problem is hanging me up, and that's losing audio after sleep. I read that you can potentially fix this by editing your DSDT, but I"m having issues even doing that.

I've tried using DSDTSE to extract my DSDT but I get an error saying "An exception of class NilObjectException was not handles. The application must shut down."

I've also tried using this Terminal command
Code:
ioreg -arw0 -d1 -c AppleACPIPlatformExpert | xpath /plist/array/dict/dict[2]/data[2]/text\(\) | base64 -D -o ~/Desktop/DSDT.aml
but I get an error saying "No nodes found"

I also did not load any custom DSDT, so I don't know if that makes a difference.

I appreciate your help man. I downloaded that application and I was able to generate a new DSDT and patch it with my motherboard config, but I can't compile successfully. In fact, I get about 164 errors. This happens before and after patching my mobo config.

In MacIASL Preferences have you set Compiler Options to ACPI 5.0 ?

Attach DSDT ill take a look for you.
I think I picked the wrong patch initially. After I selected the correct mobo it appears to compile, and the sound after sleep seems to be working. Thanks for your help.
