Okay, I tracked down what was causing the missing PC Speaker sound in the old Sierra games. Too bad I didn't figure it out before 0.61 final!

I wasn't aware these games supported the Tandy speaker, but they do. I had disabled Tandy speaker support in DOSBox, thinking I'd never need it. But DOSBox must have still reported the speaker present internally, as these Sierra games attempt to use it even when it's disabled, instead of the PC Speaker.

This is why I wasn't getting sound and Harekiet was, and so he didn't see the bug. He should have realised by the slight difference in sound that it obviously wasn't plain old PC Speaker sound coming out, but slightly nicer Tandy speaker sound!

Oh well, something for 0.62! 😀
