Also check for possible settings in other mixers (you probably have more than one): % mixer -f /dev/mixer0 % mixer -f /dev/mixer1 % mixer -f /dev/mixer2 ... Maybe the noise you're hearing is some amplified "interference" coming through a monitor channel; look for "monitor", "igain", "ogain". With a graphical mixer like xmixer or aumix-gtk, you can easily check the effects of those settings. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
