Go to start/run and type in "dxdiag"

Now go to "Music" and see if it mentions anything about MIDI.

Report back what it says.

Hi.

To my problem more details.
I've installed it like in guide (so i've download win98 alpha version, installed vcredist.exe, then installed vdmsound), but
when I run vxdsload.exe all is ok.
then when I run vxdsinit.exe all is ok.
But when I run vxds1.exe, vxdsload calls illegal operation and I must close it.

Dxdiag doesn't say anything bad about midi. Without problems.

My config: AthlonXP at 1.9 Ghz (200x9,5) , 512 RAM,
MB A7n8x-E deluxe
video: GeforceFX 5600
sound: onboard MCP-T southbridge integrated Audio Processor Unit + Realtek ALC650 6-channel audio CODEC
OS: Win98SE

I am running this in taskbar: Task Sheduler, N-Force COntrol Panel, Volume Control, NVidia Settings.

Processes: Explorer, Sstray, Rundll32, Systray

autoexec.bat: SET VDMSPATH=C:\VDMSOUNDS (it is installed right in that directory)

My problem:
Digital sounds are OK. (even after reboot it works)
Midi simply doesn't sound.
Tested games: Daggerfall + setup, Doom2

Make sure you have the Microsoft synthesizer selected in your Windows control panel's sounds and audio applet, as recent nForce drivers do not provide any other MIDI synthesizer options.

Also, be sure to choose General MIDI in the games as the MIDI device.

It seems, there is already some emulation for nvidia nforce audio under win98.
When I reboot, and run game, there is sound in DOS games, sometimes even midi... but sound is choppy, it is not very good quality, and midi sometimes doesn't play. Maybe, this emulation is causing some troubles, when I running VDMsounds.

But I don't know how to disable it. I don't know even I have installed something like that. When I run MS-DOS prompt, there is already set blaster = A220 I5 D1 T4 P300, and it is NOT set anywhere in autoexec or config .sys. So I don't understand it.

That was my post.

It may be in the device manager. Under sound devices is there something that says "legacy" or "emulation"?

Sound, video and game controllers
- NVIDIA(R) nForce(TM) Audio Codec Interface
- NVIDIA(R) nForce(TM) MCP Audio Processing Unit (Dolby(R) Digital)

Hmm doesn't look like it.

You could try double-clicking on each of those and see if there's a tab somewhere that looks like it has something to do with DOS sound compatability/emulation.

Hmm, it seems I've solved the problem. I don't need to use VDMSound anymore, because my MB really have support.
But it have really crappy BIOS for this.

Listen... I've disabled onboard midi port, and then, it have changed to port 330, and it is working.
There is not any option for soundblaster in BIOS, but my MB still supports it, as soundblaster pro A220 I5 D1. I cannot change it, I cannot disable it, but it is working.
