Hello everyone. I've been trying to mess around with the DSDT for my Sony VPC-EB series laptop in hopes of fixing HDMI audio, as well as removing patching it to remove NullCPUPowerManager.kext (some people report that that kext conflicts with LVDS).

When I try to compile my DSDT without any modifications, I get 166 errors. There are a lot of "Object does not exist" errors and "Object is not accessible from this scope" errors.

Searching through multiple forums, I found that some of the "Object does not exist" errors can be fixed by adding an "External (####)" line, but that doesn't fix all of those errors.

I've attached the DSDT retrieved from Windows and Linux, the decompiled DSDT as well as the error messages. I'd appreciate it if someone could help me fix my DSDT or help walk me through fixing it.

Thank you!

EDIT: Just took a look at diff between the original dsdt.dsl and your modified dsdt.dsl. Thanks for adding in the DTGP method for me!
