The sound in Bioshock wasn't working, and after searching for the solution I found that you can fix it by enabling stereo mix by clicking control panel then sound then recording. It fixed it but how does this effect my sound?
stereo mix is usually used as an input as a way of recording computer sounds into mp3's or wavs and saving them. I do not know how it would affect Bioshock, but I don't think there are any 'side effects'
