If anyone can help many thanks in advance, not sure what as happened or what to do but when I hit E to start a conversation there is no sound just my characters lips and the NPCs lips moving but no audio, The other sound effects don't seem normal either I have to face the object where audio is coming from and if I turn away then the audio is silent, I am on the PC version.

OK Ive got sorted thank god, if a mod sees this then please delete this,

Care to explain how you solved it?

A silly mistake by yours truly, instead of having my setting at surround sound 5.1 I must have put it at 7.1 I put right and now everything back to normal.....
