  • Stereo Output Not Working on MBP – Cross-Post

    Posted by Max Frank on July 16, 2010 at 1:34 pm

    Hi,

    I’m running an MacBook Pro with the specs below.

    When connecting speakers or headphones into the mini-jack port, I’m getting a mono or quasi-stereo signal.

    I’ve got my Audio Output settings in the ‘Sound’ preference pane set to middle [ie, in-between Left & Right].

    Is there any other reason I could be getting a mono out instead of stereo?

    Thanks in advance,

    Wayne

    Hello Wayne and welcome to the Cow Audio Forum.

    What application are you using for playback? Could it be set to mono?

    Are you certain the source is actually stereo? Try playing a CD without importing it into iTunes. Is it stereo?

    Could you have a bad cable?

    Start the Audio/MIDI utility in the Apps>Utility folder. Select “Configure Speakers” check the stereo mode to make sure left speaker is set to 1 and right speaker is set to 2.

    Regards,

    Ty Ford
