Hi, I have installed the V-Stream 878 TV tuner including the latest updates from the KWorld site and the patch. The video is fine but I just cannot get any sound at all from it. I have tried wave input and headphone input with no result. I am using a pentium D 3.4GHz with NVidia GeForce 7200 and Windows XP pro. I suspect that I need an audio driver but have been unable to locate one. If anyone can help I would be very grateful.
