I've been attempting to configure ALSA to use a ymf744 sound card
Almost all is working expect some sort of midi sound.
It appears that the XG synth is probably not supported.  However, it
appears that the driver does have opl3 capabilities(at least the driver
registers an opl3 device).  This is what I have been trying to get
to work as a midi synth.  My basic testing method has been
        pmidi -p 65:0 W2Humans.mid
and
        playmidi [-r] W2Humans.mid
Both is which seems to hang for 3 minutes(the length of the clip)
and playmidi -r seems to indicate that indeed the play thinks
the midi file is playing. I have also been using sbiload to
load std.o3 and drum.o3 as opl3 patches.

---------------------------------------------------------------------
Test update
---------------------------------------------------------------------
I've include the source for a simple hello world program to use
/dev/dmfm directly.
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <unistd.h>
#include <sound/asound.h>
#include <sound/asound_fm.h>
#include <sys/ioctl.h>

const char soundfile[] = "/dev/dmfm";


int main() {
        int fmdev;

        fmdev = (soundfile, O_WRONLY);
        if (fmdev < 0) {
                perror("Opening Device");
                exit(1);
        }

        if (ioctl(fmdev, 0x20) == -1) {
                perror("Resetting Device");
        }

        if (ioctl(fmdev, 0x25, 0x01) == -1)
        {
                perror("To OPL3 mode Device");
                close(fmdev);
                exit(1);
        }

        close(fmdev);
        perror("Done");
}


This produces the output:
Resetting Device: Invalid argument
To OPL3 mode Device: Invalid argument

        As an outsider looking in, it seems like the midi channel is muted,
        however, there doesn't appear to be a midi, fm/synth, or sythn control
        in alsamixer.  There is a wave. pcm, external midi(amongst others).
        So even if this was true, I wouldn't be able to to fix it.

        So finally my question is.  Does opl3 midi synth work with ymfpci?
        If so, what am I doing incorrect?

        Thankx
