Sound support (2), using hardware directly

[Julius Schwartzenberg <julius@zgod.cjb.net>]

Hi,

At some point there was a thread in which I was looking into using the 
OPL3 in my laptop with Dosemu. This only worked somewhat, the sound 
could only be partially be heard.

I've now set up a new Dosemu installation on another system for testing. 
It contains a Sound Blaster AWE64. I've currently installed Dosemu CVS 
from 17 July 2005.

With the following ports setting:
$_ports = "device /dev/snd/seq fast range 0x388 0x38b"
I get the same result as I got on my laptop with the OPL3 sound only 
partially working.

I thought it would also be an idea to look into using the wavetable 
stuff of the card directly from Dosemu. It seems the following port 
settings achieve this:
$_ports = $_ports, " device /dev/snd/midiC0D0 fast range 0x330 0x331"
$_ports = $_ports, " device /dev/null fast range 0x620 0x623"
$_ports = $_ports, " device /dev/snd/midiC0D1 fast range 0xa20 0xa23"
$_ports = $_ports, " device /dev/snd/midiC0D2 fast range 0xe20 0xe23"

This allows me to have pretty good music in Duke Nukem 3D :)
I haven't tried it from pure Dos yet, but it sound pretty good already. 
Also it seems I need to load a soundbank first before any MIDI plays at 
all and I haven't got the original ones from Creative, so I'm using one 
I downloaded somewhere.
Is anyone else using a similar setup? I don't know much about the AWE 
cards and it's wavetable for MIDI, but is the way I described this the 
way to do it in this case?

I'm still hoping to get OPL3 to work too though. Since the problem 
occurs on two pretty different systems, it isn't a problem specific to 
my laptop. Both systems probably use the same driver for OPL in ALSA though.
I thought that with the Sound Blaster, it might be easier to test it 
without the Linux driver, since it might be easier to get the Dos driver 
to work inside Dosemu. Could anyone comment on the possibility to use a 
Sound Blaster card completely from within Dosemu?

It would be really nice to have good sound support in Dosemu. The combo 
I have with the Dosemu Sound Blaster emulation and the AWE midi seems to 
be near perfect, but I'm really looking forward to have OPL3 support 
within Dosemu :)

Thanks in advance,
Julius
