Answer 1

I have encountered this same problem on my computer to home
theater setup.
A faulty (or too old) RCA Y-Adapter was the cause.
Don't use those cheap flimsy ones. Get one that is at least 10 dollars or more.
I tried lots these cheap RCA Y-Adapters and they all end up buzzing or humming. Some are fine in the beginning, but go bad eventually. I finally got a more expensive

and the problem was resolved.

In your case the headphone extender can also be the culprit for the buzzing.
My setup is kind of different than what have.
The RCA Y-Adapter's headphone plug goes directly into the soundcard w/out an entender. the two RCA plugs on the other end are hooked up to two "female to female" RCA couplers.
This links below are examples of an RCA coupler.

I use a 25 foot RCA cable, one end plugs into the other side of the RCA couplers, and the other end goes to my A/V Receiver.

BTW, you might need to go to the Radio Shack link twice
because it takes you to their home page first.

I hope this will help.
Good luck.

If the static is coming through only one speaker, check the speaker wire first. Make sure that you aren't running it next to any power cables since speaker wire can pick up electric fields and create that static noise you are talking about. If everything looks fine, swap the speakers. If the static comes from the same speaker, you probably need to replace it. If the static stays on the same side, you've probably got a problem with the Y-splitter. Check to make sure that the cable is securely connected to the computer. This may sound trivial, but I've knocked mine loose a few times and had the same problem.

If the static is coming from both speakers, check to see if the Y-splitter is running next to any power cables. Again, these splitters tend to pick up electronic fields and give off a static noise as a side effect. If that doesn't change anything, replace the y-spitter with one that has gold connectors and looks thicker. This will mean that you have a better connection with more insulation and the static should go away. I don't think the problem is with the computer because swapping from the headphone jack to the sound card didn't do anything. There's always a chance that your sound card is bad, but I've had this problem before and I was able to fix it using the methods above. Besides, a new Y adapter is a lot cheaper than a new sound card. It's worth checking out.

(sigh) those "Optical to RCA" converters basically artwork for Stereo or PCM indicators such as you get from a CD participant. all of them have wonderful-print the place they make it easier to realize they do no longer artwork with Dolby digital, DTS, - the sound usual for HDTV shows. Does your television be able to output PCM from the optical port? if so - a kind of converters will artwork. If no - you attempt to hook a Stereo sound gadget to a 5.a million device. because of the fact of this you're having difficulty. now and back your cable or sat container could have left/good RCA outputs which you would be waiting to faucet into. regardless of if it relatively is going to basically artwork while making use of those contraptions. It wont artwork for Disk gamers, interest structures, and so forth.

Answer 4

also could be noise off the computer ie the harddrive and fans and the speakers have to take in any interference, and you want to go from mini jack to rca if connecting to your stereo
