Never mind, I removed the x3000 and it worked! Thanks toleda!
I'm having the same audio problems, but there's talk of a new MultiBeast being released soon. Will the updated audio drivers in MB make it so we don't have to remove the "npci=0x3000?"
Do you need that flag to run?
Why? No specs, no help.I have been using multibeast 4.6.1 and choosing kexts for ALC887 (without dsdt) everything was working fine.
