I tested Win10 v1709 guests and modern Linux guests (Arch Linux). On an Arch Linux host with the latest VirtualBox a Win10 v1709 guest works fine. So this seems to only impact Windows hosts. I've tried it on 3 completely different machines, an older Sandy Bridge era desktop, a modern desktop and a current laptop. I've tried it on Realtek audio hardware with a 3.5mm microphone plug and a Logitech G533 wireless headset with a USB dongle. I tried disabling (from Device Manager) all other hardware devices except the Logitech device when testing this. I tried uninstalling the Realtek drivers as well. I tried a clean install of the latest VirtualBox with a clean Win10 v1709 guest install with audio input/output enabled from the start. Everything appears fine on the surface, audio input/output are enabled in VirtualBox settings, the devices appear in the guest, audio output works fine but audio input does not - there's only silence. The Windows Sound -> Recording dialog in the guest does not show any activity and ""Listen to this device"" does not result in any output. On the host itself it does work. I didn't see a relevant looking ticket for this so I'm submitting a new one." defect new audio VirtualBox 5.2.8 microphone, audio input Windows Windows
