Roughed in talent's audio using Premier Pro CC, sent to Audition via dynamic link. Talent's audio has been working fine in both waveform and multi track. Put a musical underscore on the 2nd audio track and now I have an issue. Talent's audio is still playing back in both correctly. The musical underscore will playback and emit sound in the waveform editor, however in the multi track editor it will not emit sound. When I hit play the playhead moves, the video plays, the talent's audio play, but the musical underscore on the 2nd track emits no sound and the VU meters register nothing. Any assistance is greatly appreciated!
