Yes. Turning all sound to max settings and using Windows to adjust the volume is the workaround that works for me as well. I hate to do it that way because I might start the game with my Win volume up higher than I would want it in the game, but whatever works, I guess.
You can adjust the volume of a specific program with the Mixer. No need to turn down the general slider. It also saves your setting, so you only need to lower the volume of DOS in the mixer once and then never again.
