No sound on Linux host (ALSA) for Windows XP guest with new VirtualBox v5.1.20

[dinosaur0]

Sound worked fine with v5.1.18, but now the driver fails to initialize with v5.1.20 on my Linux system, with ALSA as the sound backend, when hosting a Windows XP session.

Log attached.

Win XP guest on Linux/ALSA host: bad music

The new test build doesn't do it for me... See VBox-BadMusic.log.gz

I'm having a similar issue. I do not have sound on any guest OS when having Linux/ALSA host.

Gtk-Message: Failed to load module "canberra-gtk-module"

This only since 5.1.20 is installed.
