Audio / Video on host system stops working when virtualbox is run

[Lokesh]

Hello

I have a peculiar problem while running VirtualBox.

The Audio / Video of the host system stops working when a VM is spawned using Virtual Box.

Virtual Box version : 6.1

Host OS Version :
lokesh@lokesh-ThinkPad-L490:~/git/rdma-core$ cat /etc/os-release
NAME="Ubuntu"
VERSION="20.04.1 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.1 LTS"
VERSION_ID="20.04"

I am using "vagrant reload / up /suspend" commands to boot / shutdown the VMs.

This has become a major problem for me as I am not able to attend the official calls now when the VM is on as the audio does not work. As soon as I power off the VM, the media (audio / video) starts working again. There is a beep sound that comes when the VM is powered off.

Any type of solution is welcome.
Thanks!

Vagrant is not supported here on the Virtualbox forum. Vagrant just happens to use Virtualbox, and they have their own support forums.

If you can start a fresh new guest from the main Virtualbox window, without using Vagrant or any guest made by Vagrant, and still have the same problem, then please continue:

Start the non-Vagrant guest from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

Also, Right-click the guest in the main Virtualbox window's guest list, choose Show in Explorer. Zip the guest's .vbox file, and post the zip file, using the forum's Upload Attachment tab.

I think it has nothing to do with vagrant.

Looks like the VM takes the control of audio / video from the host OS when the VM is switched on.

Is there any way to stop the VM from using audio and video?

Install the guest true headless by using the "none" video card, and disable Audio in the guest's Audio settings.

I guess that's that, then.
