disable microphone when guest additions are installed

[bmn]

When guest additions are installed, the guest gets access to the hosts built-in microphone. I do not want this, because if the VM gets compromised, someone can listen.

Can you add an option to disable this please? For example with some "VBoxManage setextradata vmname VBoxInternal/Devices/xxx 0" like command?

Or is there already such an undocumented command?

This has nothing to do with the Guest Additions. Sound input/output works independently from the Guest Additions. Muting the microphone is a valid request but OTOH you can just mute the slider on the host yourself. VirtualBox is just a normal application trying to access your microphone. The host user is responsible to prevent that in the same way he would prevent that for any other application.

Thank you frank. Yes, it has nothing to do with Guest Additions. Please close this ticket. I created an updated, correct one: #12026.
