Dell Precision T3500 Audio Fix

[roadzy]

I just recently started working on setting up OS X on my T3500. Everything went smoothly after realizing that the bios needed flashed. The only hiccup was the audio. The audio was AWFUL. It worked but like if it was one notch beyond 1 it was so loud my headphones could lay on my desk and hear it. It also popped and hissed. I messed around with downloading all the different VoodooHDA version hoping one would fix it.

I didn't tried version 2.8.4 from here (http://t3500.mcdonnelltech.com/), but I did try the one from here (https://www.tonymacx86.com/threads/osx-sierra-10-12-2-on-dell-t3500-success.210713/). I also tried the ones from the Multibeast which is 2.8.6, 2.8.7, 2.8.8. Those didn't work at all. I did find a version 2.8.9 (VoodooHDA.kext-2.9.0d10.zip) which is the current in progress one. This fixed EVERYTHING! Just incase thats not available to download, I'll attach it here in the post.

This is just specifically about the audio but I'm going to document everything I did here (http://roadzy.blogspot.com/2017/07/hackintosh-dell-precision-t3500-macos.html).

Thanks for this post. Saved me a lot of head scratching. Because I've tried a lot of the newer versions. Also the newest 2.9.1, and that doesn't work; hissing and distortion all over the place. But yes the 2.9.0d10 version works a charm on my system as well.

Thanks so much for your post and the kext!!! It definitely helped give a much more controllable volume on my T3500 with High Sierra. 8)
