I have been working on and off for sometime trying to get OPL3 FM
Synth (NOT the WaveTable Synth) to work under ALSA with a AOpen
(I'm fairly sure) Ymf744B Card. I have even gone as far as writing
some simple code to communicate directly with the /dev/dmfm
(/dev/sound/dmfm) device and thus at least verify that the OPL3 was
reachable.
My basic setup is the default asound startup script, modified to
modprobe oss modules and snd-opl3-synth. The kernel driver is the
latest CVS as of The End of August, and the sbiload is the latest
cvs version. When I am trying to get the OPL3 FM Synth to work,
I use a simple script to run sbiload with the std and drum patches
as follows:
/usr/bin/sbiload -p65:0 -v $1 --opl3 \
/usr/share/alsa/banks/opl3/drums.o3 \
/usr/share/alsa/banks/opl3/std.o3
Once the Patches are loaded, then I try to run pmidi and playmidi
to see if ALSA and OSS midi is now working.
pmidi -p 65:0 W2Humans.mid
and
playmidi [-r] W2Humans.mid
Both seem to hang for 3 minutes(the length of the clip) and
playmidi -r seems to indicate that indeed the player thinks
the midi file is playing. No sound. :(
It seemed like the midi channel might be muted. So I have double
checked to make sure all the mixer controls were turned on and up,
just in case. I recall some previous post mentioning a synth, midi,
or a FM mixer control; none of which I can manage to find, and the
ones I have found (master*,wave,pcm,external,cd,etc) are unmuted and
have been tested turned all the way up.
If anyone can help/share experiences it would be appreciated.
It seems that there is at least one person out there on this list
with a similar problem with the same card(first appearing in April),
and I was curious how far he had managed to get with the OPL3.
I have tried to include text/links of various pieces of information,
which might help in a diagnosis. And a Test program for accessing
the direct FM device, in a last ditch attempt to make sure I could
talk to the OPL3 at least. The error output I get is included.
Thanks
