I've noticed this with Extreme Pinball with SB (can't remember the samplerate). GUS seemed to work ok, except that it would crash if you tried to get back to the main manu. This was a while ago though.

Although I no nothing about the GUS, I downloaded the GUS 4.11 drivers and installed them.

No more static when playing Extreme Pinball 😀 Thx for that! Also the version of DOSBox I'm using doesn't crash (at least it didn't the couple of times I tried) when going back to the menu.

How did you install new drivers in Doxbox? I never knew you could update those.

I found links to V4.11 GUS drivers and installed them into C:\ULTRASND which is where DOSBox read/writes 'something'. There's a host of patch files present so I thought they might be loaded... as I said, I know nothing about GUS cards or drivers so this may not have been necessary however!

huh...i wonder if that would work with video drivers too

No, DOSBox only expects to find patch files in the MIDI directory underneath the ULTRASND directory. I didn't know whether these patch files were available as a separate download so I just installed the drivers and there was a directory full of files 😀

AFAIK the DOS drivers are not used as the GUS device is like all other devices - emulated (this may not be the correct term for all services however). Video is inbuilt and what you have available depends on what build you're running - I run a CVS build with D3D and OpenGL[HQ] enabled.
