winecfg audio question

[Robert Reif]

Here is a patch that adds an audio driver configure button
and tries to send a DRV_CONFIGURE message to the
selected audio driver.

It doesn't work because it can't find the audio driver. However,
hard coding the driver name to "joystick.drv" does display
the joystick config dialog so it should work.  Any ideas why
it doesn't work?

Once this works, it should be possible to implement a real
config dialog for each audio driver.
