I was using Interim_Ivy_Bridge_Lion_AppleHDA_v1 in ML and it worked very well. Ever since 10.8.5 and the need for me to change npci=0x3000 to 2000, I've been able to use the MBeast kext with the DSDT edit.

I noticed, however, that the audio is louder with the MB kext and it lacks in dynamics. In 5.1 material (VLC, Blu-ray Player) the center channel is much louder and voices are overly clear, and not very well mixed. It almost feels as if the codec is stuck on a lower bit resolution (lower than 16 bit) and thus giving the feeling that the sound is compressed, although no audible compression is heard. In stereo music (iTunes) it's the same.

Going back to the Interim_Ivy_Bridge_Lion_AppleHDA_v1 kext and everything is much better.

It's the same in 10.9, btw...

Assuming the newer kext is better in every OTHER regard, can it be fixed or should I remain with the older one ?

Thank you ! :)
