Had to reinstall my system because for some reason the damn HVR-1800 would allow me to get any audio when trying to use the external connectors for plugging in my DirecTV box. I just figured it might have something to do with my running Vista 64. No matter what I did, I couldn't get any audio from those jacks. I could from the RF connectors. I tried uninstalling drivers, updating to the newest ones, everything, but nothing worked.
Well, I managed to get the jacks working perfectly with the set top box after reinstalling 32-bit Vista. NOW the damn QAM channels don't have any audio!! I don't know what the hell the deal is. Its really getting on my nerves!!! I had put on the 3.4d1 drivers that I had before because I knew for a fact that they would work. So, if they used to work before, why aren't they now?
Guess I will have to uninstall and reinstall the drivers yet again to see if thats it.
