Volume at 0 just makes it very quiet, but not off. ---------------------------------------------------------------------- Clemens Ladisch - 11-09-04 09:26 ---------------------------------------------------------------------- The AD1981B's datasheet says that the maximum attenuation is 46.5 dB (which conforms to the AC'97 specification). To mute, use Mute.
