Show customized Built-In Audio in System Profiler

It's possible to use HDAEnabler.kext to do this too, but i find this solution working better, because you can modify it to your own likings.

First off, you'll need to go here
/System/Library/SystemProfiler/SPAudioReporter.spreporter/Contents/Resources/[YourLanguage].lproj/Localizable.strings

Scroll down, and find no_info_found. That is the part you'll want to modify. I changed mine to this

no_info_found = "Realtek ALC888 High Definition Audio:

 Avaliable Devices:
 Line Out:
 Connection:   1/8 Jack
 Headphones:
 Connection:   1/8 Jack  
 Mic in:
 Connection:   1/8 Jack
 Line in:
 Connection:    1/8 Jack";

After you saved it, go check your System Profiler, Audio (built-in) tab. It should now show you're audio device
