PC to TV No sound

[bounty_hunter]

Hello all you wonderful people, I have a dilly of a pickle here. Getting back into desktop gaming I decided to use my tv ( with a vizio soundbard connected to it via optical audio cable) for my monitor. Pc is up and running but no sound. Now the PC is connected to the tv via hdmi cable, my xbox is occupying the other hdmi port on my tv. Finally the last bit of information that i think would be useful is that the xbox sound is working fine, my tv audio settings are the same for both. I don't understand what could be the problem other than software? My motherboard is a KA3 mvp motherboard.

Is the HDMI on a video card or the motherboard?

It could be something as simple as right clicking on the volume icon on the task bar, select playback devices, and make sure the HDMI thats connected to the TV is selected as the default audio device. (windows 7)

I know when I was looking for a receiver a few years ago, not all of them accepted audio from the HDMI cable. You needed to run an optical cable along side it. Is it possible your second HDMI port on the TV is set up the same way?

Depending how old your video card or motherboard is, it might not support audio over HDMI either.

Other than that, I dont know what to tell you.

So are the system specs in your sig accurate, or some kind of parody?

If they're accurate: You can't get sound over HDMI with an X800.

Some TVs have an HDMI port specifically meant for PC and will support sound for that input via separate minijack in (which you'd then connect to your sound card) - you'll only be able to get stereo with that though.

If the vid card has a HDMI port than it can do audio- but you need a special connector to go from your mobo's audio jumper to the vid card. My old 8800 worked this way.

That only applies to nVidia cards of older generations.

To my knowledge ATI has never made a card with an SPDIF passthrough for HDMI audio. They all have their own basic integrated sound chips. So if you had a dedicated sound card you couldn't actually use that for audio over HDMI.

Also nVidia went this route with the 400+ series, their new cards have their own sound chip and function as the sound card themselves.

If you want to use a good dedicated sound card in conjunction with a TV these days you'll typically need to hook that up separately via optical (TOSLINK). Though for that to be worthwhile you'd want a receiver and surround system. Might was well just use the video cards' sound processor if you're only outputting to crappy TV speakers.

In any case, an X800, if that is what bounty_hunter has (but methinks he's just trolling) predates all that. He'd have to be using a DVI->HDMI cable if that's actually the video card he's using.
