It should work as far as I know. I would try it out as resistors aren't that expensive.
You could also use a potentiometer instead of the resistor.
Good luck!

go up with voltage untill the sound card clips...
Also, I realized that putting a zener diode in parallel will just clip
the signal at the diode voltage, so it won't solve the problem.
A simple resistor in series with the piezo (of appropriate value)
should work, shouldn't it?
