MSI GTX 760 HDMI Audio

[Coldgamr]

I am using HDMI out from my MSI GTX 760 for audio and video. My motherboard also supports realtek alc898 audio. I am using a GA-z87x-ud4h mobo without a DSDT.
I have the alc898 and HDAEnabler drivers installed from multibeast and VoodooHDA v2.8.4 driver. I installed the voodoo driver when I realized my realtek driver wasn't working. I've read that having both drivers can cause issues and so I tried deleting the voodoo kext but I didnt have permission to.. even though I am the admin and the terminal said I have read/write/execute permissions.
Not sure what I'm doing wrong here. Should I uninstall the realtek driver since Im using my GPU for audio/video?

Delete S/L/E/VoodooHDA.kext, enter password when requested. Run MultiBeast/Witout DSDT/ALC898. If no 898 audio, see Mavericks: No Audio - Realtek ALC AppleHDA
