On a Linux host, really?

What does "VBox not startup up" mean? You mean that the manager will not start?

Hi

running ubuntu 18.04

lauchning

Code: Select all

virtualbox

itself is crashing....

Does the sound work fine if you don't have the HDMI audio enabled, via the Nvidia card?

PS. I merged your two threads on the same issue. Does VirtualBox crash, or does the sound crackles, which is it after all?

Hi

thanks for looking into it.

Looks like the startup of virtualbox is solved after checking "enabling 3D accelleration" .
So the virtualbox manager is starting up with hdmi displace active in xrandr.


But sound still crackling for all sound settings.

I tried Pulse audio and Alsa Audio driver. Both are crackling.

The hdmi nvidia driver i do not even see in Virtual Box Setting as audio device.
Only :
- Intel HD Audio
- ICH AC97
- Soundblaster

So only sound for IntelHD Audio in virtual box.

If I select ALSA the sound is routed to the HDMI Nvidia sound with Pulse to the onboard audio
