If I wanted to run a cable from my onboard S/PDIF sound output jack on my MSI mobo to my Panasonic HT95 A/V Receiver. What kind of cable do I use? Anyone know?

I want to see a pic of the cable so I know how this would work.

My onboard sound:

Inputs on my receiver:

Right now I'm just using regular 3.5mm output from the onboard sound (the green output) to the red/white inputs on the receiver.

A 75 ohm coax cable terminated with an RCA plug.

(a regular old RCA cable will do just fine in a pinch)

Do you have a pic of what such a cable looks like, i only know what the inputs look like, but not there names.

Oh wait would I need a coaxial input (like the orange one on my mobo) on my Receiver for this to work? Or you can you output to red and white?

My Panny receiver is just some old POS and only has Red and white inputs:

It's the exact same physical dimension as a regular RCA jack - like a composite video cable, for example (which will also work fine). Wikipedia has a bad picture of the end on their S/PDIF article:

So I guess I would need a Reciever with a coaxial input to use that right? Can't use red + white? Correct?

No point in using the S/PDIF output then - it's a digital signal, red/white is analog. You need a device to do the conversion; a cable/splitter/etc won't cut it.

Ok so I'll just continue using what I got then. I got a cable going from the green output on my mobo to the Red + White inputs on my Panny.

Adam,

as you just found out....

your reciever will not work.... the coaxial SPDIF on your mb is a digital output and the red/white connectors (TV, VCR, Aux) are analog inputs. You would need to get a reciever with an input that excepts coaxial digital.

The good thing about using a reciever is that you would be able to install a quality reciever with more quality output to your speakers... also you can get better speakers that would blow anything that is pre made for computers. but as you know... the more money invested in a reciver and speakers the higher the level of power/quality.

One thing to note... by using digital output from the computer.... today games will not be able to transmit its surround sound effects from DirectSound. It would be in stereo. Only DVD movies will be able to transmit its surround sound code. You need the analog output of all 6channel from the mb or sound card and then those signals to be sent to a reciever with 6.1 channel analog inputs in order to do surround sound in games.

I have thought about getting a better Reciever, but this one was give to me for free. It's actually one of those Reciever/DVD Player combo boxes from a HTIB kit. The 5.1 Yamaha speaker hit was given to me for free from my dad after he got new speakers for his Home Theather. So now I'm using this cheapo Panny (Panasonic) Receiver/DVD Player and the Yamaha speakers I got for my PC and for my Xbox 360. My Xbox 360 actually seems to output much better sound to the Panny than my PC. I get full 5.1 sound from my 360 through regular Red + White outputs. But from my PC I only get 2.1 sound.

Adam,

the reason you are getting better sound from the Panasonic than from your PC is most likely due to the speakers. The Yamaha speakers connected to the Panasonic combination is probably due to the power and better speakcer vs your powered speakers that are connected to your PC.

you are Not getting true 5.1 sound from your 360 connected to the analog red/white through the Panasonic. Red/White inputs are strickly two channel stereo sound. What you are hearing is a sound processing from the 360 that is simulating surround sound. Not true decoded separate 5.1 channels. The "Only" way for your 360 and sound system to give you true 5.1 is - software needs to be coded in 5.1 channel, output from the 360 needs to be either coaxial/fiber digital or 6 channel analog, then your reciever needs to be either coaxial/fiber digital or 6 channel analog input. It all starts with the software and makes it way through the hardware and finally to the separate speakers. Currently what you are hearing from the 360 using red/white output and then red/white input on the panasonic is in stereo and then simulated surround sound. (it is the same way if you had a sound card and only had four speakers .. you can do the same effect within the software to make it sound as if you had surround sound.)

Doesnt the 360 have a digital coaxial/fiber output???????

Yes, the Xbox 360 does, but remember the Panasonic Receiver unit I have doesn't have a coaxial/fiber input.

Yeah, your right the sound coming from the 360 is just Dolby Pro Logic, which is simulated sound 5.1.

The PC's onboard sound is just outputting stereo to the Panny Receiver as well, but the Panny Receiver is not doing Dolby pro logic like it is with the 360, which it seems to be something with the settings on the Receiver. Unfortunately I don't have the remote control, since I got if for free, I guess the guy who had it couldn't find the remote. So I can't change the sound settings on the Panny unit. So I'm stuck with "Super Surround" sound mode for the input my PC is in, and I'm stuck wiht Dobly Pro Logic mode for the input my 360 is plugged into.

Both my PC and my 360 are hooked up with Red + White for audio. Since thats all my Panny unit has for inputs.
