Audio: When undocking a laptop, VirtualBox cannot switch to a different sound output

[Technologov]

Host: Win10, VBox 5.0.26

Guest: Win10, x64

When undocking a laptop from a dock station, I expect VirtualBox to automatically switch to a different audio-out device. For example, WinAmp music player on native host does it correctly.

Sadly, VBox doesn't, which makes it impossible to use Skype or listening audio/video with docking station.

Steps to reproduce:

1. Start any music player or VoIP program in Windows (7 or 10) guest
2. Undock (unplug) laptop from docking station (which includes a separate USB Sound Blaster device)

Expected result: Music should keep playing with max. 1 second audio drop

Actual result: Music stops playing completely.
