Hello,
so my problem is that my speaker has no other sound but a strange noise when i plug it into my new build pc(front or rear jack), its a cm elite 311 casing, asrock h77m mobo and running windows 7 64bit.

i tried the speaker on my macbook and it worked just fine. i also reformatted my windows but the sound are still there.

i plugged in another old speaker to the pc and it also has the same problem(strange noise).

is it the motherboard audio jack or somewhat are causing this? the speaker was working fine on the new build pc before(using intel hd graphic) and after a long day i was messing with the graphic card (some problem) and finally get the graphic card to work then when i turn on my pc again it has this problem... it is really frustrating and double face palm... would buying a cheap external sound card fix this? pls help anyone?

First re-install your audio driver, download it from your motherboard's site. What's your system specs? Also check the front panel audio header and make sure you haven't shorted any of the pins there.

You've found out first-hand why on-board audio should be avoided (in general.) It is very difficult to shield the audio from everything else in the system. Some chipsets are more successful than others, but the noise will always be there, especially if your speakers have a high sensitivity. As others have hinted, you're hearing the interference from the other data-processing parts of the southbridge.

Installing another sound card isn't a guaranteed solution since noise can still creep in through the power supply. I've had this problem on my old Intel Q6600 HTPC build; adding a Creative X-Fi Platinum didn't *completely* resolve it, nor did using the optical output from a Turtle Beach card.

The solution is to throw more money at the system in the form of an external (USB) sound device with an independent power source.
FWIW, I disabled the on-board audio on my current Ivy Bridge build and bought Vanatoo Transparent One speakers...

No, that's not what I mean... you said more than once this computer is a new build, so you must have had to make all the connections to the motherboard you installed - which include the Audio Header cable that goes to the front panel connectors on the case. It's supposed to be connected to the Audio pins on the motherboard.

Have you checked to make sure you connected the cable into the correct position on the motherboard?

There isn't necessarily going to be a *cheap* solution. It all depends on your budget and annoyance factor.

Another facet to the problem is what is coming from the wall outlet--if you have a noisy municipal power supply, a quality PSU *might* help, but something that actively "cleans up" the feed is more-desirable. A lot of my equipment is also behind an APC Back-UPS Pro or Smart-UPS (graceful shutdowns during power outages are an added bonus.)

If you want to (also) continue down the external sound route and have no need for inputs like a microphone, something like the AudioEngine D1 would be a reasonable start.
