Left headphone/ear piece non-functional after eye tube repair.

I would like to know what component/cable gives sound to the ear piece. The teardown guides are vague on this. It seems to me very likely that I did not do something properly during the reassembly. I imagine the audio codec chip is working properly because the sound is crystal clear in the right ear piece.

Note that I did not mess with the left ear piece itself in any way during the eye tube repair. I am certain that this problem is internal rather than external.
