Thank you for the info.  I have made the changes as mentioned in the post.  Headphone still has a lot of noise.

VoodooHDA.kext.zip

Your info.plist is the same as mine.

 

Did you make sure to deactivate AppleHDA.kext? (remove AppleHDA.kext, repair permissions and rebuild caches.)

If you edited HDEF section of DSDT. You may need to revert it to default.

 

Try 2.8.5 (I have not tried it yet.) It works without modified info.plist.
