Trying to solve this problem, I have tried to there is only sound from the right channel (if I remember correctly, this has been reported by one user also) and the sound interruptions issue reoccurs again! After I reboot, I find that my sound does not work perfectly anymore. Installation of NullCPUPowerManagement kext is find (as reported). I have tried your NullCPUPowerManagement kext installation package on my existing SL VM (which has sound working by using your audio driver). I got some information that you may find interesting.

I'm going to try to work on a 64-bit compatible driver but for now you could run in 32-bit to get sound support working, you aren't required to run the guest as 64-bit on 64-bit hardware, I run mine in 32-bit on my 64-bit Core 2 Duo system. I forgot to mention this but the driver is only 32-bit, thats why it's not loading when you're in 64-bit mode. Do you know if that could be causing a problem? Note, my Snow Leopard guest is running in 64-bit mode (seems to be required for some reason, probably since the host is 64-bit). After firing back up, there is still no sound and the System Preferences->Sound window shows "No output devices found". In both cases, the guest freezes when shutting down, requiring me to power it off manually.

I tried both the package installer method and the manual install method. My host is Ubuntu Lucid 64-bit, VB is 3.2 Beta2, guest is Snow Leopard 10.6.3. Paulscode wrote:This doesn't seem to work for me.
