I might just try sticking in my USB function generator and 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? renato _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
