I don't know if that's any different than putting the slider all the way up in alsamixer but maybe it's worth a try. Also if you have multiple inputs maybe try the other (mic versus line in), maybe they have different levels. ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
