Ive just started this, and noticed a problem. When I answer the door to the Vault-Tec guy, i hear him say 'vault-tec' and thats it. All I get is like a whistling noise during the conversation.

Any ideas how to fix this? Seems a bit pointless playing it at the moment if i havent a clue whats being said.

Not a great start, plus it looks like I need to get a new graphics card.
