audio driver for mac yosemite on virtual box

Audio Yosemite On Virtual Box Manual Install Method

I boot up the machine again and to my surprise, the problem is not solved (I previously think that restoring a snapshot is a MUST-WORK solution.) The sound is still not working perfectly at this moment.

This is the AC97 drivers compiled from Darwin source patched specifically for the AC97 sound device VirtualBox emulates.

My host is Ubuntu Lucid 64-bit, VB is 3.2 Beta2, guest is Snow Leopard 10.6.3.

Audio Yosemite On Virtual Box Manual Install Method

I tried both the package installer method and the manual install method.

In both cases, the guest freezes when shutting down, requiring me to power it off manually.

After firing back up, there is still no sound and the System Preferences-Sound window shows No output devices found.

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).

Do you know if that could be causing a problem I forgot to mention this but the driver is only 32-bit, thats why its not loading when youre in 64-bit mode.

Im 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 arent 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.

Ill edit the topic to make it known its currently 32-bit only.

Thank you, Ill provide all the necessary info for building the driver shortly.

OmegaX: Which community are you come from OSx86, or from VBox OSE, or from Oracle, or.

I guess you could say im from OSx86 but posting this extension there was my first post in years of inactivity.

I have tried your NullCPUPowerManagement kext installation package on my existing SL VM (which has sound working by using your audio driver).

Installation of NullCPUPowerManagement kext is find (as reported).

After I reboot, I find that my sound does not work perfectly anymore.

Installation is reported to be OK, but after reboot, the sound is not improved.
