I recently re-installed windows 7 onto my pc and was redownloading and installing all my old programs when I noticed I wasnt getting any sound from my headphones. I've looked at other forums and posts and tried them but no success. I was able to get sound to play though. I tested this by recording a few seconds then sending it to my older pc to listen and I did hear what I should have if audio was playing. I use windows 7 and via hd audio deck. Thanks in advance.
