Is there any kind of debian module that will reproduce
PC speaker sounds through the sound card?
The system in question has a working sound card but
there are no apparent pins on the mother board that carry the
timer-counter output to the outside world.
There is a piezo transducer on the board that beeps just
fine but there are no pins short of unsoldering the piezo
speaker and putting a couple of pins in it's place and that is
way too much work and the system does not belong to me. I need
to hear the beeps in headphones. The sound card even has a 2-pin
input marked PC Speaker but getting the signal there is the
issue which is why I am asking if there is a software-based
solution.
Thanks for any ideas.

Martin,
I'm not aware of a module - but there are a lot I don't know about,
anyway. Just one note - it's the transducer which actually generates
the sound; it's being fed with a DC voltage. Connecting headphones to
this will only give you a click in the headphones (and probably blow the
board due to the low impedance of the headphones).
IOW, don't even THINK of doing it :)
