I was using the package, I've just installed the port, and it's using
/dev/mixer, even setting this to be /dev/mixer1 doesn't help.
it's actually trying to do this :
if (!(mxdevmask & SOUND_MIXER_PCM))
{
report (REPORT_ERROR, "rplay_audio_get_volume: pcm mixer device not installed\n");
close (mx);
return (-1);
}
so by adding a lot of lines like so :
if (mxdevmask & SOUND_MIXER_XXX)
printf("mixer supports SOUND_MIXER_XXX\n");
I now know that my sound card does the following (here's the output):
rplayd/rplayd: host_read: cannot open /usr/local/etc/rplay.hosts
mixer supports SOUND_MIXER_CD
mixer supports SOUND_MIXER_IMIX
mixer supports SOUND_MIXER_ALTPCM
mixer supports SOUND_MIXER_RECLEV
mixer supports SOUND_MIXER_IGAIN
mixer supports SOUND_MIXER_OGAIN
rplayd/rplayd: rplay_audio_get_volume: pcm mixer device not installed
So, the question now is, why does it support ALT_PCM but not PCM, and
what exactly does that mean to me ?
(Can I (and should I want to) reroute things in the driver somehow so
that PCM is actually ALTPCM, or am I jumping ahead a bit much there!)

Aha, but it doesn't seem to actually set it to max, something more like
50% I think.. I'm not too sure about this though.

The old one that used to be the default in /usr/src/sys/i386/isa/sound,
or perhaps a newer version, this appears to be VoxWare 2.9 on 3.0-Release.
[I thought we had 3.5-alpha integrated ? Didn't know they made it
commercial though, unless that's another product.]

Tried that with the old driver, but I always end up getting a lot of
things like this :
/kernel: How strange... mss_intr with no reason!
and not much in the way of working sound, well, it works, sometimes, but
then other times it stops halfway through playing a sound, or loops, or
goes all crackly, I think I've even been lucky enough to cause a panic,
after some really bad screwups! =)

I've emailed the guy who maintains the documentation at yamaha to see if I
can get one. Could be handy, although I'd not rate my chances of getting
it to work even with the datasheet very highly either though =)
Unless I know how to run the probe routines at any other time
than boot, otherwise testing is such a monumental pain!
Thanks,
Steve
