Hello. A few days ago I bought an ATI TV Wonder Pro. I have it installed, and have the cable TV hooked to it, and the video is fine. But I can’t get the audio to work. The audio on my computer works fine for any other application (MP3’s, games, etc.), but I have no audio when I watch TV on my PC. My PC has USB speakers, and an integrated audio card. I plugged the wire in the audio out on the TV Wonder Pro card, and into the line in on the integrated audio card, as the instructions said, but no sound. So I thought maybe I need speakers hooked to the sound card, and not USB ones, so I took a set of speakers that I know work fine (tried them on my sisters), and hooked them to the sound card. No sound at all. No sound on TV, no sound from MP3’s, no sound on Windows start up. Nothing. So I am guessing that the integrated audio card is dead. I was told that if you have an integrated audio card, that you can not install a second sound card. Is this true? Because I am thinking that all I need to make it work is a new sound card. But will a PCI sound card work in my system? And also, it says nothing about in under the system requirements on the box, but I heard that you need a Radon graphic card for it to work also. Is that true? Thank you for any help you can give.
