But do you know that input levels (e.g. microphone) are separately controlled from output levels (e.g. playback or monitoring)? You need to play with the mixer to set them, and Audacity has some input choice and level controls of its own. Audacity has some level meters, so you can watch for changes as you play around. You may have to click on them to make them respond if you're not recording at the time. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
