Firstly cheers for the help, I now have sound, however it resembles a dj scratching the wheels of steel. I'd better add that this is the 3 disk version of MI, 2 Double Density disks and a single density disk.
I'm guessing this is due to the IRQ or DMA settings as I've had this before with other games, the solution was to alter their values in a setup program.
However as MI doesn't have this I'm guessing I'll have to mix and match my settings till I find the right on, then knock up a batch file to change the settings and run MI all in one.
Don't suppose anyone knows the default Port, IRQ, and DMA values?
It would save me a bit of time when I get back from work!
Ding dang do, you'll do for me!
