Sound problems with Windows XP Guest

I'm running VirtualBox 4.0.2 64-bit on Windows-7 Professional 64-bit. I have a Windows XP professional guest (32-bit, SP3 plus all latest patches). Audio in VirtualBox is configured for SoundBlaster-16.

I find that audio from applications in the guest plays fine but if a guest app exits sometimes the audio continues to play. Often, this audio 'overrun' turns into a cacophony of choppy noise which continues indefinitely. I also find that sometimes a low continual audio 'clicking' will start when the guest OS is running even when no sound related things have happenned in the guest.

I have no audio problems whatsoever when the guest OS is not running.

Any ideas on how to resolve this or at least troubleshoot it?

Thanks, Chris

Don't use the legacy SoundBlaster-16 audio.
