HDMI connection from PC Video Card?

I'm planning on buying hp m9500t series with a video card with hdmi connection. If i connect it to the hdtv, will i get sound from it or do i need another connection for the sound? My purpose for this is i want a multimedia pc so i can watch movies and play games using my hdtv.|||Depending on the graphics card you have, there might be an input on the card itself for audio. That is the only way that you'll be able to get audio out of the HDMI cable. If there's not input, then you'll only transmit the video.|||Yes, a video card with HDMI outs will be able to transmit sound. Just make sure the graphics card comes with a SPDIF wire, which is the wire that connects your graphics card with you motherboard. It's usually a red and black intertwined wire. You will not need any other connections other than these, and of course, the HDMI wire.|||The HDMI connection will transfer both audio and video
