Terrible Interference and white noice through computer

post #1 of 36
Thread Starter 

Hello,

I built my own computer, has the onboard realtek for audio, and I get terrible interference/white noise through my speakers and headphones.  I am open to pretty much anything to help fix this, I'm thinking of starting with a new case and MoBo for my computer.  I have it pluged into what I think is a decent surge protector, I'm guessing upgrading to a Furman digital power consitioner will help?  From there I plan on getting a DAC/AMP, soundcard, and slowly building up my setup.

 

My question is what would be the main source of this, and where should I begin to fix this?  What are some good products that you recommend at entry price range.  I can probly put about 200-250$ a week into funds for this.  Time isn't so much a concern, I am willing to wait a little longer to obtain a better overall result.  Thanks! If you need any add'l information from me feel free to ask.

 

I believe the speakers I'm using are the Logitech Z-2300, and headphones I use the Cooler Master Sirus for gaming, and AD700's for music.  I understand these speaker's aren't great, but I would expect to get over 25% volume without horrible distortion and white noise, even without any sound playing.

My first guess is that you have the speakers plugged into the wrong jack for example the mic jack and not the audio out jack.  Secondly check that the power cord you PC uses has a ground on it and that your wall socket has a ground.  I am guessing your speakers are self powered?  If so make sure they are plugged into the same wall socket as your PC to get the common ground.

 

When you plug in your headphones are you plugging into the jack directly on the onboard soundcard?

 

Are you using an adapter that may only be a stereo adapter and not a TRS adapter?  This would mean you are missing the ground on the adapter which could definitely cause the issue.

 

Does the noise go away using a different audio player?


Try updating the drivers as sometimes this can cause issues like this.

 

Lastly, please describe in better detail how you are running sound from your PC to your speakers / headphones.

 

For example:

PC via Foobar2000 --> USB Cable --> Grace Design m903 DAC --> Kimber RCA Interconnects --> Balanced Ultra Desktop Amp --> Single ended headphone adapter ( 1/4 inch ) --> Denon AH-D2000 headphones.

 

This way we can find any issues with your audio setup you may be overlooking.

Self Powered no ground on the power cable.  I have my computer and speakers, with some other components plugged into a grounded surge.

Rear analog directly on MoBo.  It is not in mic jack, double checked.

Not sure here, the speakers are directly wired to a 1/8 in jack that plugs into the back of the powered sub. One for left and one for right.  No adapters used.  The coolermasters hook up through 2 USBs which are hooked directly to MoBo usb slots.

 

Does the noise go away using a different audio player?

All players have same result.  Have not tried River or Foobar.

My OS is windows 7 64 bit.  Speakers go like such.  Pc via winamp-> Aux out -> Logitech Z2300 

Cooler masters run directly from USB to the integrated amp/hub.  AD700: PC via winamp ->Front aux out -> AD700.

 

For example:

PC via Foobar2000 --> USB Cable --> Grace Design m903 DAC --> Kimber RCA Interconnects --> Balanced Ultra Desktop Amp --> Single ended headphone adapter ( 1/4 inch ) --> Denon AH-D2000 headphones.

Answers are in red.  I am going to get a DAC tomorrow, possibly amp too.  I got some AV40s today and will be changing out the old Logitechs with them.  I will repost my setup and update if this fixes anything.  Would I still be able to use the powered sub at all?  The thing bumps and I would like to still take advantage of it with the AV40s.  Thanks!

Try USB first, if that doesn't work, try using optical toslink to the dac, that solved all the problems I had with PC noise.

Ok guys, I updated my system a bit, and am still receiving white noise. The white noise appears when I play audio through any player.
New setup PC via Foobar->Audio engine D1 Dac via USB->M-Audio AV40 via standard RCA
I put together a video to show my setup in more detail, and give you an idea of how awful the white noise is.
Thanks for all the help guys.

So it happens with two speaker sets and two soundcards?

Maybe you are using unshielded interconnect and it's picking up some radio noise? What happens if you max output volume on the computer and lower speaker amp gain?

Not sure what you mean by 2 sound cards it's going from my motherboards optical to the D1 to my powered speakers through the D1.  It's just one speaker set, I changed to optical to D1 and still getting same results.  Now goes Pc via Foobar -> D1 via optical -> AV40 via ****ty RCA cables.  Could the rca be causing white noise?  Also I used the supplied speaker wire which was included with the AV40's to connect the main powered speaker to the right speaker, could this cause white noise?  Thanks for all the help and advice.  Max output on computer and lower speaker gain same result.

Have you tried another source? Eg, iPod->AV40

Hmm, good idea, still seem to get some white noise, not as bad, but still noticeable.  I am getting better RCA's and speaker wire next week so I will try using those and see if I helps.

What's your gain structure like? 

 

Ideally your computers volume is maxed, your DAC should be line level, and your speakers should be adjusted to the listening level you want.

Computer is max, speaker is about half and I adjust by dac.  I also tried to set dac at half and adjust by speaker with comp maxed, both give same result.

I mean, you had exactly the same noise with Realtek -> RCA -> Logitech speakers, right? Or was it different? What happens if you connect AV40s directly to Realtek line-out?

I watched your video and it seems that this noise appears only during playback. Are you absolutely sure that it doesn't exist in these recordings (did you play them elsewhere)?

Everything before analog cables should be maxed (unless it would cause clipping). Disable all software volume controls, make sure that bit depth is set to >=16, max volume at computer and DAC, adjust with speaker amp.

Noise was very similar with logitech setup.  Had a little added static, but pretty much the same.  When I plug AV's directly into computer analog out it has horrible static noise, constantly, and when I play it has white noise.  The white noise does only appear when I actually play music.  It isn't the music, all songs produce it.  I disabled all sounds, enabled application control, ect. within the control panel.  When I plug the speakers directly into my iphone, it doesn't seem as bad, if there at all, with the white noise.  I tried maxing computer and DAC and adjusting by speaker, same result.

You said that you heard noise in headphones. Was it only this constant "Realtek static" or also hissing during playback? What about headphones connected to D1?

Someone found a similar solution by uninstalling the Logitech drivers:

 

"Now I have a fresh windows 8 install. I got the Xbox music pass and started listening to music again. I enjoyed it for hours. Until... I decided to install the G930 driver (I wanted the equalizer, and also the headset's volume control to work).  Bad idea: cracking sound was back."

Also listed on the link are a few other solutions one of which may work for you.  Give those a try and let us know if you find a solution.
