.Sh AUTHORS
.An -nosplit
The original SoundBlaster DSP and SoundBlaster 16 MIDI, and Yamaha OPL-3
drivers were written by
.An Hannu Savolainen .
The SoundBlaster 16 DSP code was written by
.An J. Schuber Aq jsb@sth.ruhr-uni-bochum.de .
Improvements to the OPL-3 drivers were made by
.An Rob Hooft Aq hooft@chem.ruu.nl .
.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.
.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.
