I want to do some small DJing with my computer, but get a nasty feedback (that is what a friend tells me, really i don't know) when I plug the audio cables into my stereo. The noise is a low buzzing sound wether or not I am playing anything. I don't know if it is my sound card, my amp, or my lines running in between. Just so you know, I don't have anything special. My sound card is a sb live value, Radioshack cheapies for the audio cables, and a used-to-be-the-sh!t-10-years-ago Technics receiver. I did my comp with another receiver, but have the same problem, so I am beleiving it is the wiring or card or both, but then again, both receivers could be sub-par. Any help or suggestions on getting rid of this would help.
All you audiophiles out there, I NEED HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

It sounds like you a) have a nasty grounding error, or b)have connected the headphone out to your reciever.
To resolve a) you can try to connect both your computer and the reciever to the same outlet.
To resolve b) you need to connect the line out to the reciever.
That's all I can think of right know so I hope it resolves you problems.

Oh, another thing. Do not connect to the phono in on the reciever. Because old recordplayers deliver a weak signal the phono input amplifies the signal. Therefore you will get a nasty buzzing sound if you connect a standar line signal to it.

<< Radioshack cheapies for the audio cables, >>
HMMM... I think I'd start there. If that doesn't work maybe reloading the soundcard drivers can help. And like Platypus said. Make sure you're not going into the "PHONO" input.
Not that Im an audiophile by any means, but my guess would be the Live!.
The reason I say this is cause I have a similar problem, and even though I only use my setup for personal use, its annoying.
I have an SBLive! Value plugged into my Marantz reciever/amp.
The Marantz definately isnt at fault, its pretty old, but its sound quality in terms of purity is still about as good as it gets.
My speakers have really crappy cables unfortunately, but what really makes me think its the Live! is that the buzzing can be heard in my sub as well, and the cable going from the amp to the sub amp is definately not a cheapo one, and neither is the cable going from there to the sub, and the sub itself is very high quality as well, so no weak links on that chain, cept for the Live!.

Also make sure your SB Live is mounted away from your modem, if you have one installed. Your sound card could be picking up some noise from that. Hope that helps.
i'm assuming you are going from your pc to your receiver yes? the sb cards have a pretty sh!tty floor noise level, that static you hear. one thing you can do is to make sure your volume sliders (main volume and front channel volume sliders) are set to 1/2 or less. and use the tape or md/dat input on the receiver side. turning the volume sliders down lower will help even more. you'll just have to increase the volume on your receiver. also, keep the audio cables as far away from any power cords as you can. if they have to cross make them cross at 90 degrees.

StrangerRanger, do you know of any cards that have good output quality?
I'm somewhat tempted by the Sonic Fury by videologic(Turtle Beach Santa Cruz in the US).
EAX and A3D support would be nice, which is yet another reason why the SF seems nice.

This is a good theory but simply isn't the case. Your cables should just be shielded properly.
What adapter are you using to change the 1/8" plug to go to your receiver? It is a 1/8" -> RCA jack converter? I used to do it like this and while it isn't the best way, it still should work without noise.
On your sound card, there should be a line out, and a headphone jack as well. Try plugging in from both of these to the receiver to see what results you yield.
Check what previous posts have said, that your line is not connected to the PHONO input, it has a boosted signal and will cause this buzzing.
If that doesn't solve your problem, then it's times like this that I want to remind people that Creative cards simply are NOT the best on the market. I've never been a fan of their soundcards personally but I also have nothing against them. I own a $26 AOpen AW744Pro which has a nice optical out going right into my Denon receiver. Sounds beautiful. My roommate has the Live! Platinum 5.1 and my soundcard has better waveaudio than his, probably due to the fact that i'm using the DAC of my receiver but the soundcard produces game sounds beautifully as well. Anyhow, if you want to do some serious recording, the absolute best card to get is the Yamaha DS2416. It will run you about $400 if you look around but it's the best card out there, hands down. If you don't want to spend that much, look for a card with RCA outs to go to your stereo, there aren't many out there but there are a couple.

I would agree with Platypus. This sounds mainly like a grounding thing. The fact that the buzz comes from both the regular speakers and the sub indicates that the noise enters before the amp stage, perhaps even before the pre-amp, or at the inputs. As has been said, shielding the cables is a good, fast, cheap way to start the detection process. Even just aluminum foil, for testing purposes. Good luck!
It's a dreaded ground loop. Do a search for possible solutions such as plugging everything into the same outlet, removing (yes, removing) sheilding from the cable, or buying or making a ground loop isolator.
If any of your equipment uses a 2-prong, non-polarized plug, try plugging it in backwards (do not use a 2-prong adapter with a 3-prong plug). Do this with one piece of equipment at a time until the buzz goes away.
Other possible solutions:
1. Tie a ground wire to the chassis of of all the devices. The best way is to run separate wires, and tie them all together at one point, but in practice a daisy chain of 18-guage also usually works well. If the device does not have exposed metal, do NOT try to connect a ground wire to it because it may have a "hot" chassis, one not isolated from the 120VAC.
2. Disconnect the audio cable shields at one end
3. Isolate at least some audio cables with a coupling transformer. These are commonly used in car stereos, and Radio Shack has a very good one (they had 2 models, and I don't remember which).

How does that rule out the crappy output/input lines u are using between the card and the amp?

Cuase I've used that same cable with a portable CD, hooked up to the same equipment aside from the CD, and it was fine.
Ok, it seems that I will start at gettin gbetter cabling and a sound card. Any suggestions? I need to know where to look too or at least what the specs need to be, otherwise I will be looking blindly in the aisles of RadioSh!t and Circus City. Thanks fo everyones help....
You're starting at the wrong end -the more time consuming and expensive end (that will also not necessarily solve the problem).
like they said, try better cables, and removing the ground, often soundcards output higher than a line out signal, giving you a headphones out which is higher than a line out, if u have any friends in the audio industry, try to get something called a di box, or director's inteface box, that will remove the ground and also lower the signal, by using switches on the side, then think about upgrading to better hardware, such as a echo (www.echoaudio.com) or lxyn studio (www.lxynone.com) card, they make excellent cards, there are other options also
Go to Radioshack and buy a 3 prong to 2 prong AC adapter. You can get a 2 pack for .97 cent or so. I had a ground problem (loud hum through speakers) with my amp and this took care of it instantly. Give it a try.

I always knew cyber-security was a crime, does anyone at the FBI know anything about anything?
