VirtualBox 6.1.20/6.1.22 breaks PulseAudio
I don't know how it's possible at all, but VirtualBox 6.1.20/6.1.22 breaks PulseAudio - as soon as you run a guest OS which has audio enabled, PA starts crackling and you'll need to restart the daemon to fix audio.
System info:
- OS: Fedora 33 (fully updated)
- Kernel: 5.12.5 vanilla
- VirtualBox 6.1.20/6.1.22 from https://download.virtualbox.org/virtualbox/
- Device: Realtek ALCS1200A
