When speakers are connected and the volume is turned up to normal levels, the noise is very loud, approx 20% of the signal. This noise appear when the card is not playing sound and there is low CPU using. As soon as you play sound, noise stops. If you pause xmms or any player, noise returns. Muting all the channels does not stop the noise, but if you exec: "alsactl power 0 off" ¡noise stops!, but you have to exec "alsactl power 0 on" to use the card again. The driver could do the same than "alsactl power 0 off" when it isn't playing sound. If you use the lastest nforce drivers (1.0-0283 or newer) noise stops. ====================================================================== ---------------------------------------------------------------------- jdthood - 04-09-05 17:26 ---------------------------------------------------------------------- Submitter: You were asked to provide additional information.
