Whenever I run the container it requests the use of the microphone on the
laptop. No other virtual machine does that. This has been tested on 3 occasions
several weeks apart with 3 different downloads.

### Steps to reproduce:
1) download
https://build.opensuse.org/package/binary/download/Virtualization:Appliances:Images:openSUSE-Leap-15.1/kiwi-images-vagrant:virtualbox/images/x86_64/Leap-15.1.x86_64-15.1-virtualbox-Build1.24.vagrant.virtualbox.box
2) do vagrant box add <name> <filename.
3) do vagrant init <name>
4) vagrant up --provider=virtualbox
5) wait for setup to finish

### Expected behaviour:
Microphone is not used

### Observed behaviour:
The the machine uses the host's microphone
