Add Audio Hex String to plist.

[tech4]

So here is my issue and question. I already have a string for my graphic card and it works great but now I want to add one for my audio. How to I add the hex to the com.apple.boot.plist?

 

This is what i have:

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<string>mach_kernel</string>

<key>EthernetBuiltIn</key>

<string>y</string>

<key>GraphicsEnabler</key>

0069006f006e0000000500000038</string>

 

 

 

</dict>

</plist>

 

 

Now the question is: Do I add a second "<key>device-properties</key>" then add the hex string or do I just a new string line?
