VoodooHDA in VoodooHDA Posted April 13, 2009 It's also working on HP 6720s with ADI1981. I did only have speaker-out with the ADI1981 Azalia kext, but with this one all in/outs seem to get detected. I finally get sound on headphones! Haven't tested input yet. After sleep the PCM volume gets reset, and audio is distorted. I hope this gets fixed soon!
