The silent sound

Brilliant detective work, and a great interpretation of the clues. BUt after reading the story it is still not fully clear as to if the actual fault was in software or in hardware, or in address assignment. Changing code was the fix, of course, but I am not sure that was the actual problem.

But thanks for an interesting tale.

I was impressed by your troubleshooting method.  If it hadn't been for the SIMM card clue, it could have been much more difficult.

Of course it is always simple AFTER you have found the problem.

And it is always simple when it is someone else's problem.

A simple case of software debugging?

I did not have the source code for the driver, only a binary file.  That made it a LITTLE more difficult...

This sounds like a simple case of software debugging, not a particularly esoteric problem. I will add that there are all sorts of ongoing issues with PC sound. For example, when my Windows Vista machine goes to sleep, after it wakes up the sound system is down cause it can't see any of the hardware.

Well, I haven't heard that term used in a while.  I wonder what facility we have to do a similar analysis today.
