Odd NPC sound and subtitle behaviour

[Henrydylan]

Hi, has anyone came across this before?

When I first load the game everything is fine but after a while when I talk to an NPC there is no sound and their lips don't move, plus the subtitles flash past too fast to read. This is very annoying when you're trying to follow the story to complete a quest.

Any ideas please? Is it a glitch?
