DESCRIPTION
This driver covers the SoundBlaster family of cards including the SoundBlaster 1.0 to the SoundBlaster 16/SoundBlaster 32. The awe driver provides AWE32/64 functionality. This driver is provided in FreeBSD versions 2.0-current through 3.0-current. You can also configure more then one card on a single DMA using the conflicts keyword in your configuration file. This is useful for boards with more then one type of emulation.

BUGS
Since the SB16 uses the same IRQ and addresses for the different drivers, some of the snd drivers will not be probed because the kernel thinks there is a conflict. This can be worked-around by using the "conflicts" keyword on the sb16's device line.

Current version doesn't support mode changes without closing and reopening the device. Support for this feature may be implemented in a future version of this driver.
