Take a look at the packet radio scheme, IIUIC it more often than not
uses the sound card for output. Since there are 8 LEDs and 8 levels
you can get away with one byte for each LED. For example, high nibble
for address and low nibble for value. How to decode it at the
receiving end is another matter. Hmmm, a PIC?
