While I was looking for some differences between the two CD-ROM versions of Jazz Jackrabbit, I found some really weird sound crackling when the music volume is set really low. Then I checked earlier versions and they have it as well. Doesn't matter if it's a shareware version or even the registered ones. It can be reproduced even in Holiday Hare 1995.
Tested some other levels and seems like some instruments/samples are missing as well. If I make the music a little bit louder I hear almost everything plus the crackling as well. Turning up the music volume even more removes the crackling. Tried messing in the config file but couldn't fix it. The only two workarounds I found was to use Gravis Ultrasound or using the built in mixer. But that needs sbmixer=false, because every time the get's launched it set's back everything to max volume.
I can't see anything special in the debugger, only a flood of SBLASTER:Raising IRQ messages, that goes on, and on, and on!
Both 0.74 and SVN has this issue, but I'm not sure if it's an emulation bug. I don't remember if this can be reproduced on real hardware. Never changed the music volume back then. Can anybody check if I'm not the only one who has the issue? Testing on real hardware would be awesome as well. If the game is buggy by design, shame on you Epic! Nah just kidding... still love Jazz Jackrabbit. 😀
