Hie guys! I've an on board sound card and a PCI Tv card, when I install windowsXP, I'll have to move the speaker jack to the sound card for sound from the hard drive MP3 and movies, and if I want to watch the TV, again I'll have to move the speaker jack to the TV card. That other cable that connects to TV card audio out to Sound card Line in will be connected and will only work when I'm using Vista. The TV card came with it's drivers cd and the pc motherboard also has it's chipset and driver cds (Vista & XP). When I install the TV card drivers in XP, the installation completes well but right at the end sends a message like "error installing device...etc", but with Vista the driver installation completes well without an error message. When I load with TV application in XP, the audio source will be the sound card and no other option to change to Line In as is report in Vista. What could be the problem, is it the motherboard chipset, TV cards drivers or WinXP? I've tried XP service Pack 1, 2 & 3 but did not help. Heeellllppppp!!!!
