Sounds like you're having the same problem I was having when I picked up my hauppauge winTV card with dbx audio, before dbx audio was supported. I solved my problem(with lots of help from nice people here on the multimedie mailing list) by identifying the chip on the card that handles audio, and sifting through the data sheets relating to the chip and writing an initialization for it. You might want to pull out the card and take a look at all the chips on board and see if you can identify the one's that could possibly handle the audio and go from there. - Matt On Wed, 22 Dec 1999, Donald Burr wrote: > I just purchased a new TV+FM radio tuner card at a recent computer show. > The box is labeled "TView 99", and there is no indication of who > manufactures it, although I am told that these devices are made by a > company called Askey. > > Anyhow, I plugged it into my system, and everything is working great under > Windows 98.
