I am running Virtual Box version 6.1.14 with a Windows 10 guest and Mac OS 10.15.6 as the host on a MacBook Pro 2020. As soon as I open any app which requires the guest to capture sound from the microphone, the entire virtual machine crashes. I was able to reproduce the bug easily by opening Audacity in the guest as well as a conference chatting software called Teamtalk. However, it also crashes if I open up the Sounds pain in Windows Control Panel and navigate to the recording tab. Doing so is meant to activate the microphone in order to show a VU meter showing how the sound levels are. I found a similar bug report, ticket #19758 which spoke of a crash which happens when the webcam does not ask for permission from the host to be captured, and I will post a link which takes you to the Apple Developers page which shows how to properly ask for permission for microphone capture. I believe doing this will solve the crash issue. https://developer.apple.com/documentation/avfoundation/cameras_and_media_capture/requesting_authorization_for_media_capture_on_macos Thank you for reading, and I hope this will help you solve the issue. If anything else is required of me, I look forward to providing assistance and more information. Attached below, (assuming I can figure out how to do it) will be a log in which I started up the VM and navigated to Control Panel and opened up the recording tab in the Sounds pain.
