How To Enable Sound On Mac Os X In Virualbox Incoming Tech

• The guest OS X detected Intel HD Audio, and the AppleHDA driver worked. However, no audio input & output devices were found on guest OS X. On the host OS X side, the VBox.log shows that.
• Some other things to note is that in VirtualBox for Mac OS X, the audio is disabled by default. To enable the audio, select Settings (the OpenSolaris virtual machine must be powered down) and then Audio. Select Enable Audio and set the Host Audio Driver to CoreAudio: Leave the Audio Controller as ICH AC97.

EDIT: Added installer package for easier installation.

Complete Guide To Fix VirtualBox Errors While Installing Mac OS X At the WWDC 2018, Apple released the new macOS 10.14 Mojave — Packed with a significant number of features. The newly designed macOS is integrated with advanced security in a new interface, unique appearance, new features, new functions. I install Virtualbox5(which is newest version) on Mac mini which has newest version of OS X. Later, I installed CentOS7 on this Virtualbox and install another Virtualbox5 on CentOS7 for setting up Ambari. I am sure the Virtualbox on the Mac is VT-x enable. However, the VT-x setting on the Virtualbox on the CentOS7 is default disable. I recently move to ubuntu 12.04 from windows. I run mac os x in vmware workstation. In windows it runs properly but in ubuntu no sound at all. I googled the issue but cannot find an answer. If anyone helps i will be appreciate. Thanks in advance.

Put this together after setting up an OS X guest in VirtualBox and thought i'd share with the community.
This driver supports both Leopard and Snow Leopard guests
(Please note this driver is for 32-bit mode only)
To install, download and run package in guest, reboot and enjoy sound!

To Install manual way (Simplified for those who aren't familiar with kext loading):

You can use Kext Helper to install if you don't want to use the terminal: http://cheetha.nethttp://web.mac.com/v1.42ghz/Kext_Helper/Software_files/Kext%20Helper%20b7.zip
It's recommended to delete Extensions.mkext after still to ensure the new kext gets loaded.
Terminal method:
1.Extract the zip to your guest OS X desktop (not into a folder, literally to your desktop) this means there should be a file on your desktop called AppleAC97Audio.kext?
2. Open Terminal, (/applications/utilities/terminal.app)?
3. Type sudo -s in terminal then your admin password following this, now you should be root.?

4. Type sudo mv /users/(YOUR USERNAME)/desktop/AppleAC97Audio.kext /system/library/extensions ?
at this point the file AppleAC97Audio.kext should have disappeared from the desktop,?
5. Type sudo chmod -R 755 /System/Library/Extensions/AppleAC97Audio.kext
?6. Type sudo chown -R root:wheel /System/Library/Extensions/AppleAC97Audio.kext?
7. Now, CLOSE TERMINAL ?then go to /system/library/caches/com.apple.kext.caches/ and trash? Extensions.mkext
(This cache will regenerate automatically on boot with the current kext library)

8. Reboot and enjoy sound support!
Anyone looking to build these drivers see the source here: http://www.opensource.apple.com/source/AppleAC97Audio/AppleAC97Audio-5/
UPDATE: x86-64 source with VirtualBox tweaks here:

Note: This is just the source and requires XCode to compile, theres some issues with the audio quality that came with the 64-bit port that I haven't the time to track down so i'm putting it up to the community and the VirtualBox devs to take a crack at it, the important thing is this source is full 32/62-bit compliant.
