Covox Help

Can't believe I didn't think of this until like two weeks later.

Anyway, I'm trying to get the Covox sound output working with MegaTraveller 1: The Zhodani Conspiracy. I'm using DOSBox Staging and I have it configured to emulate covox (NOT disney) on the LPT port. It's attempting to work, it makes a "tick" sound then goes dead every time a sound plays. Any help would be greatly appreciated.
