Connecting a Sound-Card to a Digital Receiver for 5.1/7.1 Surround Sound?

post #1 of 12
Thread Starter 
I can't really find an answer here and I sense some confusion.

I have a [ame="http://www.amazon.com/Sony-HT-SS370-Surround-Theater-System/dp/B0035ER1QE/ref=sr_1_1?s=electronics&ie=UTF8&qid=1307318973&sr=1-1"]Sony 5.1 system[/ame]. I want to connect a sound-card to it. The on-board audio is thin and boring.

You see where it says "COAX IN VIDEO", "OPT IN SAT/CATV", and "OPT IN TV".

My manual says those are the input slots for audio. So depending on what kind of output your sound-card has, you use either a [ame="http://www.amazon.com/Mediabridge-Shielded-Coaxial-Digital-Connector/dp/B002BXCNDQ/ref=dp_cp_ob_e_title_1"]Coax Audio Cable[/ame] or an [ame="http://www.amazon.com/AmazonBasics-Toslink-Digital-Optical-Meters/dp/B001TH7GSW/ref=sr_1_1?s=electronics&ie=UTF8&qid=1307319208&sr=1-1"]Toslink Digital Audio Optical Cable[/ame].

So, I'm wondering...is that it? You connect the GPU's HDMI or DVI cable to the TV/Monitor. You then connect the audio cable to the output on the sound-card and into the input on the receiver, choose the mode on the remote and you're good to go?

Use HDMI if you have from your video the Receiver will do all the work anyways and have less cables if not go Optical.

Doesn't it use the On-board audio?

If you are talking about the GTX580 at your sig you can connect with hdmi to the receiver and then to your monitor and have 5.1 sound with no sound card.
Your gfx card can do 7.1 sound.

Right, that's what I am doing right now. But I want to buy a sound-card 'cause on-board sucks monkey nipples.

If you really want to use a sound card, then you can either buy one that supports Dolby Digital Live or DTS Connect so you can pass 5.1 sound to your receiver with COAX or Optical cable.
There is also the Asus Xonar AV sound cards that have HDMI IN and HDMI OUT so they inject the audio in the HDMI cable.
But what's the problem with using the onboard sound from your graphics card?
Nowdays when you buy a sound card, you buy it more for its analog output stage and for headphones, with an receiver that portion of the sound card isn't ever used.
And almost all new games only use software mixing and don't use any advanced hardware support from sound cards.

Hmmmmm...I understand.

But when I play music during the day (I only use headphones at night) the music sounds...a bit bland to me. I think it could be better. Am I wrong? redface.gif I think my speakers are good. When I play Blu-Ray movies in my PS3 it sounds amazing. Maybe it's Winamp? I'm playing Lossless files.

That's a big deal with the games just using software. Didn't know that. Thank you. 1+ Rep. If it won't make music or DVDs sound any better screw it, I guess I'll just get it for headphones. That'll change what I look for in my purchase.

when i used my sig for my htpc with my titanium HD i used an optical out for my Sony receiver (STR-DH510) got something like [ame="http://www.amazon.com/gp/product/B0002J2MTQ"]this [/ame]for the optical (tos link [the rca port look alike] to mini plug)

Edit: as for sound cards, yes todays onboards are starting to sound better, but sound cards can mak it sound a bit better and also allow you to tune the audio to your liking (in the HD, op amps)

Well, for my audio it says
"Sony AVAMP-1
NVIDIA High Definition Audio".

So from doing a bit of reading it seems it's not actually the Onboard Realtek HD. THAT is used for the headphones currently. And when it goes to the receiver it's made better. It doesn't sound so nice IMO...a bit thin.

So if I choose to output my sound-card I connect the Coax or Optical Cable like I said in the original post? Just like that?

Edit: bah she can wait.. but yeah, use the adapter, plug it into the optical out (set the settings to output though optical out in windows 7) and then you should be able to connect a optical out

took a quick pic of the back of my computer:
