Gaming HDMI issue no sound

[RemixDeluxe]

Hello guys I am trying to watch a movie off my computer and watch it on my TV which is HDMI compatible. I am able to see the screen successfully bur I can't hear any sound. Anyway to resolve this issue?

I am using a Windows 7 computer.

I went to control panel > Hardware and Sound > change system sounds > playback > and when I got there it was only 2 options to choose from "Speakers" and "Digital Audio (S/PDIF)." It was default to speakers I switched it to Digital Audio but I didn't get any sound from the TV and the computer was mute too. Is there something I need to download to get the sound going?

Update the graphics card drivers. That should also come with HDMI audio drivers if your graphics card supports it. If it doesn't, then you're SOL.

No idea why his card would have HDMI if it doesn't support it, so you should be okay on that front.

FYI, there are a few versions of HDMI. The first versions were video only and did not carry the sound channel. My media laptop is like that, even though the tech specs of the 8600M is supposed to have dual-link DVI (which means it can carry sound and video).

The version in common use these days is HDMI 1.4a.

I know this one........

HDMI can transfer video and sound ( maybe the really old ones only video ), but in order to do that on your PC, you have to do something else other then fiddling with the system settings.
What you need to do, is hook up your sound card to your video card with a tiny cable inside your PC (every relatively recent sound card has a connector in one corner for this porpoise ) .
If you think about it, the HDMI port comes out of the video card, which is then plugged into your PC motherboard, and so is the sound card.
Without any physical connection between the two, how's the video card supposed to get and send the audio signal of your PC ?

Through the PCIe. Graphics cards often have their own audio controllers, so it'll completely bypass your sound card and use the graphics card to output audio. Here's a quote from the HD 4870 spec sheet:
QUOTEHDMI output support

All display resolutions up to 1920x10802
Integrated HD audio controller with support for stereo and multi-channel (up to 7.1) audio formats, including AC-3, AAC, DTS & Dolby True-HD4, enabling a plug-and-play audio solution over HDMI

Of course, it's not as good as dedicated audio cards (like the X-Fi card that came with my motherboard), but you won't notice the difference without a really good sound system (e.g. 7.1 audio).

That doesn't seem to be the case with RemixDeluxe.
He didn't specify his PC specs, I'm willing to bet he has a dedicated sound card not connected to the video card.

@remix: you probably have an "old" video card that doesn't support audio through HDMI, you will have to connect an extra wire for the audio.

As originality pointed out, on most card, you don't have to physically connect a wire between the sound card and the video card.

QUOTE(Originality @ Aug 17 2011, 06:21 AM) a really good sound system (e.g. 7.1 audio).

the number of channel is, in no way, a measurement of quality. you can have a 200$ 7.1 system and a 2000$ 2.0 system.
what makes quality is the amplifier and the speaker set

Either way, I've never had anything better than a pair of crappy speakers throughput my life, except for when I had a somewhat expensive headset. I've little idea of what audiophiles seek with their expensive sound cards and sound systems that can't be obtained with the inbuilt audio of my monitor.
