I also have the same problem. I dont have any sound audiable from my TV Tuner Card. There is a Device TAB in the Properties of my TV Card, Where we are propted to select the Correct TV Input and Audio Input at the very first use of our TV Tuner. Here I can see that there are three types of Video Input, Compsite, TV, S-Video. We selct TV here. But for Audio no device is seen but my Installed motehrboard Audio driver is visible in the avaiable Audio devces. But no Sound. I also tried connecting speakers to teh motehr board and using a line in cable from the TV Tuner. Still It dont work. I use Windows Xp with Intel 945 GCNL Board. Previously I used to have a P3 with Win 98 System. Where I used to get audio in both cases when I connect Linein or Conect Audio device directly. But now ID ont get audio when I connect Speakers to motehr board. But I get sound when I connect them to the Tuner Card. IN this case I Can;t record sound along with teh video. this is the Challenge I have . Anyone Please suggest a resoluton.
