Virtualbox HostAudioNotResponding error on new system with ALSA

I'm running a fresh install of Arch and have ALSA sound working. I've installed virtualbox and am trying to create a Windows 2000 guest. As soon as I start the guest to boot off the installation ISO, virtualbox gives me this warning:

No audio devices could be opened. Selecting the NULL audio backend with the consequence that no sound is audible.
Error ID: HostAudioNotResponding

I have "ALSA Audio Driver" selected for the "Host Audio Driver" and have tried all three "Audio Controller" options, all give the same result. I've Googled this extensively and only see this problem in relation to considerably older versions of virtualbox, so I'm thinking I've missed some configuration step in my system. Hoping this rings a bell for someone here!

Here is the portion of the virtualbox log file that seems to address the audio config leading up to this event. It makes me wonder if I need to specify my soundcard as the "default" somewhere...

Re: Virtualbox HostAudioNotResponding error on new system with ALSA

Apparently I didn't Google well enough, searching on portions of the log file turned this up - appears to be a virtualbox bug sad
