hi,
same pb, no sound after sleep (GA-Z87X-UD3H using HDA version 898, osx 10.6.4).
I will try the multibeast 6.1 revert solution, however I customized the proposed script unloading/loading AppleHDA.kext into an .app :
This app require to have a modified version of your /etc/sudoers configuration to not be compelled to enter your password after sudo, like adding a line :
username ALL=(ALL) NOPASSWD:ALL
(of course, beware, security...)
The script launched by the app is :
#!/bin/bash
say -v Zarvox 'no sound'
sudo kextunload /System/Library/Extensions/AppleHDA.kext
sudo kextload /System/Library/Extensions/AppleHDA.kext
sudo killall coreaudiod
say -v Zarvox 'sound now enabled'
Here the .app :
