Hi, Sorry - I should have included that I'm on 4.0R.
Just got this reply from someone else too:
-----------------------------------------
are you running 5.0-current or 4.0-stable?
there is support in 5.0-current for yamaha chips
(definately the 724, i'm guessing the 744 too) you
just need "device pcm0" in your conf.
if you're running 4.0-stable, you might want to try
to manually MFC the source down. the files you need
are /sys/dev/sounds/pci/{ds1.c, ds1.h, ds1-fw.h}
and then add
dev/sound/pci/ds1.c optional pcm pci
to your /sys/conf/files and build a new kernel.
i have no idea if this will work... so proceed with
caution and expect failure.

---------------------------------------------
I'll give it a shot, unless someone knows that
I shouldn't bother.
Thanks much,
k

Ok. I think we should definitely pow-wow on this so that we can analyze the big
picture and take a broad horizontal view across the big dollar items.
