he is using the fact that the WRT has a serial port. he writes the
sample data to the serial port, which is connected to a PIC that in turn
has a speaker wired up to it.

he is not doing real D/A conversion in the traditional sense.

i do not believe that you will not be able to find a D/A converter that
speaks a protocol that you can implement in software.
