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.

The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
Lithium-ion battery prices will drop rapidly over the next 10 years, setting the stage for plug-in vehicles to reach 5%-10% of total automotive sales by the mid- to late-2020s, according to a new study.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
