index | next in thread | raw e-mail
Hello,
This is a patch to correct a couple of problems with the SoundMan Wave
device driver.
1) Looking at sb_dsp.c it appears that if SMW_MIDI0001_INCLUDED
is not defined then junk is downloaded into the microcode ram.
This patch changes the code so that no microcode is downloaded
if SMW_MIDI0001_INCLUDED is not defined.
2) There wasn't a default setting supplied for JAZZ_DMA16 (which
is needed to support the SoundMan Wave) so as a simple nicety
this patch adds a default to sound_config.h.
3) It would be nice if defining SM_WAVE automatically defined JAZZ16
since the JAZZ16 code is required in order to support the SoundMan
Wave. This issue isn't addressed by this patch since I wasn't
sure of the convention in use for handling this type of issue.
Other then that the driver seems to work well with my SoundMan Wave.
Sincerely,
John Wehle
