The first thing to suspect is that the Audio IC repair didn’t go smoothly. If the “new” symptoms roughly correspond to the Audio IC repair, then I would inspect the workmanship and use that as a clue.

Assuming the Audio IC was properly replaced (with jumper on C12 at least) and there no obvious signs of missing, dislodged or bridged components, then I would start probing the the ARC circuit (taptic engine) and work my way from there.
