I have a similar problem, but the volume of VLC within Windows gets lowered at random moments. Not only when I get an IM in Steam.
It looks like this is a feature of Windows, which lowers the volume of applications when a voice-application starts a new conversation. So it is probably not a bug in VLC.
You can disable this feature as follows:
Right click on the volume icon in the system tray, and choose "Sounds". Next, go to the tab "Communications" and choose the last option "Do nothing". This will disable the feature.
Unfortunately, I like this Windows-feature, because it also lowers the ingame-volume when starting a voice-chat in Steam.
