Hello all,
I got to work on this stuff much sooner than I thought (in regards to the messages above ^^) and have updated to install folders for both versions in the original post to remove the excess aptio fixes and (hopefully!) fix the audio issues people are having. I say hopefully because I tested
@RehabMan 's fixes and they seem to be working for me but I haven't been able to test with headphones yet but I don't see why they wouldn't work as well. I used the ALC-298 non-a .dsl version for my laptop with the latest version of CC.kext installed to /L/E. All files should be in the updated downloads.
As for the extra VoodooI2C improvements, I was unable to get the patches to compile properly for myself but it seems the general advice is that changing the files for VoodooI2C is something each user should do on their own. I also don't have anything for the battery display issue yet but ¯\_(ツ)_/¯.
I have not added any changes for DVMT-prealloc. It seems that most issues with this were not an issue from my guide(?) correct me if I am wrong.
