Thank you, but it doesn't worked for me
Okay I tried this when I had lag and noise in my sound...this worked perfectly, just make sure you install the entire package and follow instructions exactly. Hope this helps.
This method partially worked for me; I've edited my Info.plist, now my sound card works and there's no noise, but the sound crackles and if I change my settings in "Audio MIDI Setup" I got the same.
Moreover, I can't change the speakers settings from "Stereo" to "5.1 Surround" and only the front speakers are recognized.
I can't believe that I can't solve this problem..
