The sound quality of sample-based (tracker) music on my Sound Blaster 16 CT2290 leaves a lot to be desired in DOS.
See this audio clip I recorded from my Sound Blaster's line out jack for examples: https://instaud.io/21JL
For Jazz Jackrabbit (the first half of the clip), the audio quality is terrible under "Pentium" settings in the game folder's setup.exe options. **However, for some very strange reason if I run the SB16's diagnose.exe and go through the motions of that, the quality is fine again until I close and reopen the game.**
I tried multiple combinations in the Jazz setup options, and they all result in the same situation.
I would just settle for running diagnose.exe every time before starting a game as a strange work-around, but however with some games like Epic Pinball (the latter half of the clip I linked to), the quality changes seemingly at random when selecting different pinball tables and going back to the main menu etc., probably because the game uses multiple EXE files for the different pinball tables.
In games like Alien Carnage/Halloween Harry, the quality just plain sucks no matter what I do, unless that's how the game is supposed to be (which doesn't seem like it from clips on YouTube, though those could be emulated). It COULD just be a Epic Megagames issue.
Sound effects on games like Doom and Wolfenstein 3D sound fine.
Anyone have any ideas? In case it's relevant, my machine is using a Socket 7 motherboard (Asus P5A-B) and the Award BIOS. For drivers I believe I'm using the ones from Phil's Computer Lab's "4-in-1 machine" resources. Changing the CPU speed through setmul, disabling/enabling cache, etc. doesn't change anything either. Thanks for the help.
