Have you installed the full Gravis software suite including the patch files? There should be a folder of ~5-6MB of .pat files within C:\ULT (according to your autoexec.bat entry - by default they are in a 'MIDI' subfolder). You can also 'upgrade' the default patches with the 'Pro Pats' pack - you should be able to find that on archive.org or similar; it was released back when the cards were new and had some slightly nicer sounding instruments compared to the standard Gravis provided files.

Without the patch files you won't get any music - most games (even those which natively support the GUS) don't supply their own.

Games which don't natively support the GUS (i.e. games expecting an Adlib card) also won't produce any sound unless you run one of the Gravis emulation tools like SBOS (for Soundblaster & Adlib emulation) or MEGAEM (for GM/MIDI emulation).... frankly they're very hit-and-miss. I always ran a vanilla SB / SB16 alongside my GUS Max back when I bought one when they were new, for compatibility sake.

Thank you for your answer. I downloaded the Setup-Folder from https://retronn.de/imports/gus_config_guide.html This folder includes the .pat files. But what do I do with them?

Edit: I think, it wasn't the best idea to download the setup-folder instead of installing the suite. Now, I need to figure out, where I can get the correct file in order to be able to install the Gravis suite. Maybe this will also answer my question, what I need to do with these pat-files.

2nd Edit: Hopefully, this is the correct software: https://archive.org/details/gravis_ultrasound_v4.11

I removed everything I had regarding this guide:

https://wiki.preterhuman.net/Gravis_UltraSoun … s_in_Windows_95

and then installed the 4.11 Software from archive.org: https://archive.org/details/gravis_ultrasound_v4.11

I was only able to start "install.exe" from in Windows 95, not DOS. Because in DOS the installer didn't recognize Disk2, but in Windows it was fine. At the end, I had everything in "C:\Ultrasnd".

Then, from DOS, I started "setup.exe" (inside of "C:\Ultrasnd"). Everything worked fine, the driver installed and my autoexec.bat was automatically updated. After I added "C:\Windows" to the PATH-Variable in my autoexec.bat, I was able to (automatically) install Software like "Patch Manager", "UltraSound Configuration" and "UltraSound Mixer".

This is my current (updated) autoexec.bat:

I loaded some Patch files like this:

(not sure, if I selected the correct ones and if I need all of them...)

The configuration looked like this:

(I also tried different values here, like IRQ 5 instad of 3)

And the Windows Multimedia-Seupt and DeviceManager looks like this:

(not sure, if it is correct, that the device manger only shows my MPU-401-Card.)

Current state in Windows:

• Wave-Files still playing find - Win95 Startup-Sound plays also fine.
• I have Sound in Doom, but only high-pitched noise, no melody
• No sound in Monkey Island
• Weird noise in The Settlers 2

Current state in Dos:

• Doom works absolute find with FX-Sound and Music
• No sound in Monkey Island
• Only FX sound in The Settlers 2

Edit:

After executing sbos.bat from the C:\ultrasnd directory and hearing the confirmation "SBOS installed," I had sound in Monkey Island under DOS. However, I've had no luck getting sound to work in Settlers 2 so far.
