ATTENTION!
The hardware interface of this card contains registers not used for normal operation, but potentially dangerous and not possible to disable. Potential damage ranges from frying the card to frying motherboard or external equipment connected to its outputs.

Currently this driver does not support MIDI, joystick input, or the multi-voice capability.
There is currently no way to control the volume of the DAC for SoundBlaster Audigy cards.
S-PDIF digital output does not work for SoundBlaster Live! and SoundBlaster Audigy cards.
