(re: Sound Problems on a WIN98)
First of ALL – You should try to change the settings in the install.exe – I think what suits you system is selecting “General MIDI Sound driver”.
If you can supply additional info about you audio card- this will be helpful.
{Control Panel=>System=>Device Manager=>Sound and…=>Click on you sound-card and properties=>specify important information.
Also, Control Panel=>Multimedia=>Go to the MIDI settings}
