Character dialogue missing at Chapter 1 end

in front of the non-stormy lighthouse with chloe. It even goes back to normal when Max blacks out and sees the storm-ridden lighthouse but then when she snaps out of it, yet again the Character audio dies

The game has been running perfectly up until about 5 minutes before the end of chapter 1. The missing character dialogue only occurs. The music is fine and the subtitles are there ... but no words.I wondered if anyone else encountered this problem, or is there a possible fix ??Thanks.
