After scratching my head for awhile, I gave in and try booting your files. Just as you noted, webcam and audio both are not working. After comparing line for line and making different changes on the Config.plist and rebooting, there was no changes to the webcam and audio. I know it has something to do with IRQ so I look carefully at the HPET patch and notice a difference in the patches you have and mine. After making that one change and reboot, all usb port and audio started working. 

Here's your new config file, add the SSDT to ACPI. Enjoy!
