Question on Audacity and M Audio USB quattro on IBook

  • Hi,
    I dont know if this is a audicity problem or if possible at all, but I do not find way to listen to my guitar
    and the output of audacity without recording. When recording everythink works quite fine. I can hear
    both, the playback and the new recorded track. Whats missing is, to play along and listen to the
    sound of the audacity playback and the guitar sound both over the headphone without to record.

    Is this possible at all ?

    I'm running Audacity 1.3beta on a G4 IBook (OS X 10.4.7) with the m audio quattro usb.

    Any hint will be helpful.
