  1. Ok I have a Samsung 32" HDTV and I have a DVI to HDMI cord hooked up to it. My problem is i'm getting no sound thru my tv, when I click on my sound tab on my system tray the green bar is moving up and down like sound is playing but nothing is coming out. BTW I have a Nvidia GTX 460 so i'm sure it's capable of sound thru the DVI to HDMI cord. Any ideas?

    DVI only carries video, not audio. HDMI carries both video and audio. You can't use DVI for sound

    I looked up this evga gtx 460 based on your system specs pulldown and it has an hdmi out. If thats your card just use hdmi.

    Don't buy a $30+ cable for it though unless you just have a lot of money.

    Why was I able to get sound thru the DVI to HDMI cable before?

    Were you using mini-HDMI to HDMI cable?? and not DVI to HDMI? I believe that card has 1 mini-HDMI port and 2-DVI. You'd need a mini-HDMI to HDMI cable to connect to your TV

    You can also check the nVidia spec yourself

    Try looking in Control Panel->Sound looking for playback devices or something like that and select a different device if you have a choice. By coincidence I have your same motherboard as you have (listed in your specs) but I have a different one connected to my hdtv. On my htpc I didn't get sound thru the hdtv speakers until I downloaded a driver from the video card's (in your case nvidia's) website.

    tony beat me to the punch :)

    You might still have your onboard sound card enabled. The "green sound bars" you're seeing may reflect your onboard sound. Look in CtlPnl->Sound under Audio and check if your gtx sound card is selected as the default device. (here's an example of a PC with two sound cards enabled)
