VirtualBox 5.0 running Ubuntu 14.04.02 video/audio too fast

[kansas city shuffle]

Problem is the video/audio is playing back too fast when watching Youtube videos or any kind of video/audio playback in general. This sounds like a chipmunk type effect on fast-forward.

I am running a VirtualBox 5.0 on my OS X host machine with Ubuntu 14.04.02 as the guest.

Tried:

1) I've uninstalled VirtualBox 4.3.8 VBoxGuestAdditions and installed the version for 5.0.

2) And this solution I tried, but doesn't work:

Anyone have any ideas on how to address this?

With the guest shutdown, try running this in the Mac terminal…

Code: Select all

VBoxManage modifyvm "machinename" --audiocodec ad1980

the volume level may change, If so, run alsamixer in the Ubuntu guest terminal and increase the volume level.
