The endgame music plays right around the beginning and at random times throughout the trial.
Edit: shortened complaint and made it more specific.
+1 Exact same issue on PC.
Literally none of the issues I saw were fixed except getting stuck on a pallet as killer. You can still get stuck as survivor, Bubba's chainsaw keeps revving after you finish a run, and the endgame music still goes on in the middle at random times
