I have the 1993 Broderbund educational software "The Treehouse" running fine in DOSBox (good graphics, sounds, voices, music) except that in a few places spoken voices are silent. One instance is in the Theater where spoken sentences such as "At night Bonga Bot juggles in the middle of nowhere" are silent. I am using a Dell XPS 8940 desktop PC (new in 2020), Windows 10, and DOSBox 0.74-3. I've tried various Sound Device choices in the program setup but no results were helpful. Suggestions?
