[Solved] How do I know if a motherboard's HDMI will support audio?

I'm building a HTPC and am going to use the on board graphic and audio to go to my TV. I see a lot of motherboards on newegg.com that have HDMI outputs, but it is hard to tell if they will support audio. Is there a way to find this out easily (say by manufacturer or by something in their name)?
Is there a way to tell if they just output stereo or higher say 5.1?

Thanks

Steve

If anything it should be in the motherboard's manual. Just go to the manufacturers website (ie. support.asus.com) and look for the manual (after specifiying the correct board you're looking for) and download it.

Not a problem! Glad i could help

If you need anything else feel free to ask x)

Well that's another way of getting info. They usually do reply, but it can take days if not weeks.

But i don't see why you wouldn't get audio in your hdmi. I mean your board has built-in audio correct? Well that should also be transferred to your hdmi. I don't know about the 5.1 deal though.

Well usually that's the case. What board is it you want to buy?

Most boards will have the option to set the audio via HDMI or the regular port (3.5mm). That might just be the case with the board you want.

I cannot believe how fast I got a reply from Gigabyte. They confirmed that their boards will do stereo sound, not 5.1:

Here is a link, but I'm not sure that it will work:

Answer : Dear customer,
No, All HDMI out only provide Stereo, to connect 5.1 audio out, you need to have receiver which has HDMI port in and 5.1 speaker ports out .

Best regards,
