Hi, I've modified the plist of VoodooHDA v2.8.4 so that it works with VT2021. I did so by merging the v2.7.2 for VT2021 plist with the one in the v2.8.4's kext. When I use v2.7.2 and Mavericks goes to sleep I have no sound after it wakes up again. This v2.8.4 version doesn't have that issue. Could you make this part of MultiBeast? Replace the VoodooHDA v2.7.2 for VT2021 with this one: VoodooHDA v2.8.4 for VT2021. Cheers.
