Optimus disabled.

 

Edit: Weirdly enough, going into System Report, I can see Intel High Definition Audio under the Audio tab. Before rebooting after installing the kext, I can see things like HDMI out and Line out, but I still cant get anything out of the speakers.

 

After reboots, the dropdown under Intel HD Audio just disappears.

Found something. Opened System Report again, and it appears the kext isn't loading at all.

This confuses me because kext-dev-mode is enabled.

... What?

 

I've used both of those commands an unhealthy amount of times and only now it decided to work properly. FML!!

 

Regardless, audio is working, and now the system is perfect! Thank you for all of your help, Jake Lo, and sorry for having you go through my struggles. :)

Apple has remove the chirping sound when you click on the volume control. Try playing a video or audio file.

With Yosemite, the "chirping" sound is now a configurable option in the audio PrefPane.  ;)
