Hello, I just got a brand new Dell XPS 420, it has Windows Vista Home Premium in it. I was having trouble with the sound card ( ADS Instant HDTV PCI audio) but after I took Norton out I was able to hear. Now the problem is I can not talk in Sound recorder or any other program. The one I use the most is Flight Simulator (online flying with Squakbox) and team Speak. When I start team speak or sound recorder etc I get a message saying "TDSoundin.Open: No sound driver is avalible for use" what do I do to fix this problem? Please, I really need help, it took along time to get up enough for this computer ($966 USD) its my second in 8 years.
