I'm using RC4 SVC 6/20/06. Whenever I play a DVD I have to turn the volume up really high to hear it. However when watching TV I don't have to do this. I have a stereo mini phono plug going from my built on sound card to two RCA jacks on the back of my TV. (so I'm just using a stereo 2 speaker set-up) I have the windows volume turned all the way up. I have tried every combo audio codec/ audio renderer possible, and there is no difference. What can I do to fix this?
