If you have a really nice HDMI Graphics cards with HDMI out that will sound awesome.
Optical is digital, him using a sound card won't really improve anything. The processing is being done by the receiver. Think of the optical cable more like an extension cable to use the receiver as his sound card.

This can distort the sound (again probably not noticeable) because of the different rates of conversion.
The signal isn't getting "converted into light" any more then the signal is getting "converted into electricity" for the coax cable.

You are actually getting LESS conversions using optical then coax, since the signal is natively digital, coming from a PC.

OP, use the hdmi out on your 6870. It supports bitstreaming bluray audio, regular spdif does not.

I was under then impression that coaxial transmits the digital signal from the mobo, whereas optical has to convert that digital signal to light first. I'm almost positive that is how it works.

Sorry I keep thinking of RCA cables whenever anyone says coax.

I'm just not sure where the impression that there needs to be any conversion for an optical cable. It's just a different transmission method. The optical signal is less prone to interference, so is theoretically better.

digi coax vs optical argument? lol.

Anyways, sound cards like stx or omega has analog coax that you can plug into that receiver. So potentially there are sound "quality" "improvements".

I tried for hours to get that to work but it just wouldnt let me output sound alone via the HDMI on my 6870. CCC recognised the reciever as a monitor according to the display control and the only way to get audio down the HDMI was to set the reciever as my second monitor which tuned off my actual second 22" Acer lcd.

If I didnt set it as a monitor then the sound config in the control panel just showed the ati HDMI audio as unplugged.

If your Gigabyte is like mine, you has good codex onboard. I tend to keep it simple. Digital coax out to an amp with hi-end DACs. The less processing the better. I don't see the reason of processing it anymore then I needs to.

How you have it setup is fine. You may want to setup ASIO for audio playback. For better SQ you could get a USB DAC, but then you'll be limited to 2 channel so might as well leave it as is.

Are you not using your computer as a video source? I'm not sure how you would send only sound without having the monitor enabled. The 6870 has support for up to 3 displays. The reason CCC is disabling your secondary Acer is probably because it's hooked up via dvi and you are at the 3 monitor limit. You need to hook it up with displayport.

From AMD's website:
Quote:
To enable more than two displays, additional panels with native DisplayPortâ„¢ connectors, and/or DisplayPortâ„¢ compliant active adapters to convert your monitor’s native input to your cards DisplayPortâ„¢ or Mini-DisplayPortâ„¢ connector(s), are required. SLS (“Single Large Surfaceâ€) functionality requires an identical display resolution on all configured displays.
You can get an adapter for cheap online if your 6870 didn't come with one.
