Audio Advise

I'm not sure if this is the right place or not. My question is, will I get better sound quality if I run my audio through HDMI from my graphics card to my TV/monitor then to my surround receiver via coax. Or, should I go from my mobo to my receiver? Thanks.
 
You're not going to get much (if any) change running sound from your GPU, you'd be better off having fewer cables running around the place.
 
well, i think it depends on what kind of compression you're using. lossy compressions such as Dolby Digital or DTS will work perfectly using analog, toslink or coax connections as well as HDMI. lossless compression formats (Dolby TrueHD and DTS-HD as well as DTS-HD Master Audio) won't run over toslink or coax.

let's say you wanna use HD-audio:

- analog connections using the decoder of your AV Receiver

- HDMI connections (at least 1.3a)

imho, in such a case, analog connections will offer a better quality if suitable cables are used. especially if you're using an onboard audio codec. your AV Receiver is specially built to decode such audio streams, so let it do it's job :-)
 
There is some variation in sound chips (though they are mostly all Realtek) from mobo to mobo, so in some cases it can be different.

For my mobo the onboard sound is awful, and for some reason there is a sound card in my keyboard, so I use that, and its just about all I need actually.
 
You would get better sound quality through the HDMI. HDMI is loss less audio offering UP TO 48khz. Because a MOBO uses analogue you can FORCE 195khz through it but your speakers would crack. You can always settle with a nice sound card that is in expensive such as the Xonar DX by ASUS. $130, 196khz, slim, 7.1 and VERY nice.
