To disable integrated intel graphics: backup all the intel kexts from /System/Library/Extensions and Remove Them

To Enable Sound: Try VoodooHDA or The Specific Kext for Your Codec

Best way to turn off your Integrated graphics isTurn it off from bios but for that you must use mod bios which quite risky ..... :):( and for sound voodoohda is good as niresh said but u can use dsdt also but it need more modifications According to my research that the laptop having 2 graphics (switchable) will never switch from integrated to GPU like we do in windows (Power saving mode to high performance mode)Coz Apple use his proprietary technology to switch between 2 video card this technology is not documented yet so it's impossible that ati or nvidia in this sense will work a day. Also with laptop with hp and nvida mux, nvidia will never work,it's not a problem about muxless or mux,problem is Apple technology is not documented... :)
