Hello all,
The only way I can get the mic or web cam to work on Catalina 10.15.4 with Virtualbox 6.1.4 r136177 is using terminal to run sudo Virtualbox.
If I run the app within finder then Virtualbox crashes the moment the Guest tries to use the webcam and the mic never works.
When I run in terminal using sudo then terminal asks permission to access the webcam and mic. I double checked that Virtualbox was not an option in System Preferences -> Security and Privacy -> Privacy -> Camera and Microphone. I added virtualbox to the Accessibility section manually.
I only found this reference to the same problem... viewtopic.php?f=8&t=97141
What am I missing?
