.Sh 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.
.Sh 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.
.Pp
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.
