I'd appreciate any hints. I do that all the time, so it definitely is not a problem. I find on my card that the output volume is controlled by a combination of 'volume' and 'mix' settings in mixer(8). I also must have the 'igain' set to something above 0, but the volume isn't directly controlled by it. -- Carl Johnson carlj@peak.org
