Best way to connect pc to reciever

post #1 of 35
Thread Starter 
Ok heres my current setup:

I have an Onkyo Avx-380 reciever and 5.1 speaker setup and Im currently running the sound from my rig to it via the onboard optical on my mobo.

My question is would getting a soundcard produce better sound and give me a better way to connect the pc to the reciever? or is optical the best way in the first place

Here's a picture of the back of my reciever so you guys know what inputs I have:

Optical via onboard is good. No reason to get a sound card.

well thats +1 for the optical so far

Only thing is I swear the realtek audio manager is dropping the Dolby Digital Live 5.1 sometimes, maybe its just me but turning it off and then back on seems to make things sound better. Maybe im just imagining it.

In addition to what Crazy wrote, all the optical connection is doing is sending binary bits, 0's and 1's. A sound card will theoretically do the job better, but in the real world, there really is no difference.

Analog on the other hand, that is a different story.

Forgot to add, optical is your best bet.

No, Optical is best. Better leave the processing to the receiver. That's what they do best. Even when running via HDMI, I choose optical SPDIF for audio. Think of it as the cleanest way to run your audio out of your PC.

THat's exactly how I run my HTPC.

yes. Gigo is a rule. Garbage in Garbage out.. IF you put a 192 db or higher sound card and then plug that into your reciever you will get Studio Audio.

If you have a really nice HDMI Graphics cards with HDMI out that will sound awesome.

It may depend on whether you are running PC video via HDMI through it. If not, optical.

Actually coax is theoretically better than optical. I'm not sure about HDMI, but that may also be better than optical too depending on the cable version.

In all reality you won't notice a difference, but the reason behind me saying coax is better than optical is because of the additional conversions needed for optical. Optical is light, so if pure digital is coming from the mobo (1s and 0s) it must be converted to light, then back to digital (1s and 0s) for the receiver to decode. This can distort the sound (again probably not noticeable) because of the different rates of conversion.

Anyways a sound card wouldn't help you in the least because digital signal is coming from the mobo exactly as it is stored on you hard drive, so a sound card would only act as an expensive pass-through.
