[Wine] Forcing Wine To Use Audio Device/Mixer

[Falcata]

Well, I've got multiple sound devices on my system (integrated HDA SB ATI sound card, headset connected to USB sound card, and my webcam's built-in mic).  Unfortunately, Wine does not always use my integrated sound device for some reason.  So, instead it will do one of two things: go to the headset or the webcam.  Going to the webcam is an auto-fail, and if it goes to the headset it prevents me from using Skype.  Or, if skype is already running, I get no sound in Wine apps.

The problem is also unusual because of how the game, Elder Scrolls IV: Oblivion, behaves.  It will use the normal audio on the game's launch window, but switches to one of the other devices when the game itself starts.  Is there any command-line option, environment variable, or registry key I can use to force wine to always use a specific sound device or mixer?
