No, in most cases. The sound card should pass the audio through your graphics cards HDMI.

what?

I may be wrong but I am pretty sure from all the HDMI graphics cards I have seen that the graphics card has its own sound processor on the card to do sound so therefore no, adding a sound card and the sound card process the sound via the HDMI will not work unless there is some witchcraft that I don't know about

Wait...the entire point of this is to watch a movie on ur TV or Monitor? You can always use your graphics card for purely display, and your sound card as...a sound card. Or do you mean you have non-PC speaker system, that you wanted to hook up for you to your PC?

Wait...i thought HDMI graphics cards do NOT have their own sound processor, where did you hear that from??

EDIT: Here is a good read from someone who has more technical knowledge than myself.

"An HDMI video card does not have a sound processor and it does not have analogue support. It is not really a soundcard, it is a conduit for HDMI audio Most motherboards these days have 7.1 out from the motherboard sound chip so you can get 7.1 analogue out, but used on these often arent much cop They may be slightly better than the DAC in a medium to low priced amplifier though. A good analogue soundcard trumps all for quality, this includes external DACS (ie via USB, SPDIF). Yes, exactly right, the amp has a sound processor as well as an analogue converter The graphics card is just a conduit for the digital audio However, computer programs (like video players, music players...) can also perform their own signal processing witho a soundcard a soundcard. For example, Winamp lets you EQ the sound and send sound to more than 2 speakers with stereo input. However, some of these utils degrade the sound quality, it depends how good your sound system is, how good your h and if you are bothered by it. btw, PCM is the best quality you can get HD audio codecs sound quality is not affected by where it is decoded to PCM when using HDMI.

First off reps for all!!

I have heard 2 diffeent thing, one is when you dl a new driver you click on custom install and there is a option to do so. Then i have heard that there is a cord that goes from the sound card to the gpu.

I have a xfi in my closet, so should i installl it or not, and will it work with my gpu so i can have sound on my tv?

That is what tells me that it won't make a difference, your graphics cards can produce sound on their own as it stands

This is with my sound processor on my mobo disabled via BIOS and I still have sound via my TV

Another thing that set me off that they are different is that my sound card can do 24 bit 192khz sound but with my HDMI it only will go up to 16 bit and 48khz



@OP

If you have the spare time there is no harm in putting it in your system to see if it makes a difference. On newer graphics cards there is no cable to go between them any more. the sound via your HDMI should just work without having a sound card though.

Your graphics card bitstreams through hdmi, no different than using optical output. No hardware sound processing.

so I can still use my sound card, and not on-board for it to work?
