* Driver for Creative Labs SBLive! series and probably PCI512.
*
* Known bugs:
* - inversed stereo at ac97 codec level
* (XXX jdolecek - don't see the problem? maybe because auvia(4) has
* it swapped too?)
* - bass disapear when you plug rear jack-in on Cambridge FPS2000 speakers
* (and presumably all speakers that support front and rear jack-in)
*
* TODO:
* - Digital Outputs
* - (midi/mpu),joystick support
* - Multiple voices play (problem with /dev/audio architecture)
* - Multiple sources recording (Pb with audio(4))
* - Independant modification of each channel's parameters (via mixer ?)
* - DSP FX patches (to make fx like chipmunk)
