Hi,
I have just updated to VirtualBox 3.1.2 and have noticed the audio 
levels seem ALOT lower than the previous version (3.0.51 from the ports 
tree).
At first I thought that there was no audio at all until I turned the 
speakers up by about 30%
I tried running XMMS on the BSD host and the audio levels are indeed 
VERY different (with BSD being ALOT louder)

Has anyone else seen this?

The host is
