The same behavior here, I'm using Kubuntu 20.04.3 as host and guest, VirtualBox version is 6.1.26. On Audio page of the settings Audio is turned ON, Audio Out is ON, Audio In is OFF, so it shouldn't use the microphone according to these settings. Nevertheless microphone icon pops in KDE System Tray every time when machine starts. I've got another VM, Windows 7, with the same Audio In/Out settings, but it doesn't use the microphone when it runs. The sole difference I noticed that Kubuntu guest uses "ICH AC97" audio controller and Windows guest uses "Intel HD Audio" controller. These settings were done automatically, I didn't change anything on this tab since the installation.
