We have an application that when it executes stock it was written to play a wave file.
Now for a hearing impaired person we need it to light an LED instead. Know of anything?
I am thinking along the lines of a Mini-RCA jack (output of PC Sound) to an LED converter.
Anything on your site that I might be able to purchase? I would really appreciate any advise.

You could also go with USB, Parallel Port, or serial port.
If you wrote the application it would be fairly easy to implement lighting an led when the stock executes, otherwise your right you would need a circuit similiar to a sound level meter that would light, problem is you have to know what level the user has set the volume in order to properly light the led.
Since this can vary, going with a port is a better solution.

Here are some kits at Jameco. One is made for sound level detection and the other is a voltage level detector. Either one could probably be used. You'll have to get someone to build it (kid in the neighborhood?) and add the cable to plug into your speaker/headphone jack. If you don't know anyone, hang out at a local techie kind of place (computer store, electronics store, etc) and ask around. I'm sure someone could put it together for a few dollars.
