I get no sound from my audio track There are numerous reasons why you might not hear anything from an audio track: The Metro volume fader in the Instruments Mixer window might be turned down. Open the Instruments Mixer window (Command-I), find the name of the audio Output associated with the track in question (look at the bottom of the Instruments Mixer window), and drag the fader up. Also check the Master fader at the far right of the Instruments Mixer window. If you use the Mac’s internal soundcard, your Mac’s internal amplifier could be turned down. You may need to adjust Volumes orSound Out in the Control Panels. Open the Sound window by choosing Apple menu >Control Panels > Sound (not Monitors and Sound). Also, make sure no Mute buttons are checked in the Soundwindow. You may have a MIDI output assigned to an audio track. Look in the Outputs column in the Tracks window. Your track may be muted. Uncheck the M column at the left side of the Trackswindow.
