buzz when scrolling??

[rwest1389]

On both my speaker and headphoens coming out of my soundcard, a scratchy, humming/buzzing sound is made when i click the bar on the right to scroll up or down a page. If I click it, it doesn't make the noise, but when I move it up or down it does. Its not loud but still noticable for listening to music (and checkin head-fi). Kinda gets annoying, I was wondering if anyone has had this problem? Is it just my soundcard (which isn't great)? Motherboard?

any thoughts are appreciated.

It is electrical (duh) interference with the other cards/things in your case.

Sorry, but it's been too long for me...dunno what you can do to eliminate the problem.

it's the sound card in a hot bed of RFI generated by the computer. Put your sound card in the lowest slot possible and see if that helps.

Yeah I have that problem too, except I get it with my USB DAC.

I've isolated it to my monitor. It's an LCD monitor. Try scrolling with your monitor off and see if that is the source.

My Abit AI7 mobo has this problem. Apparently it is the inductors around the cpu that is causing the problem, slapping some magnet on it fixed the problem. The buzzing sound on didnt just occur at the speaker output, it occurs on the mobo itself....yes...the mobo makes noise...

I've stopped using my laptop as a source because of this

I always assumed it was due to a lower-quality power supply. For example, my parents' computer uses an Antec Sonata ver. 1 with the supplied PSU (Antec TruePower 2.0 380 watt). Antec's PSUs have been drawing a lot of flak for shoddy production values.

But since this is a laptop, *shrug*. kin0kin's idea certainly is interesting. Maybe some time I'll pop open my parents' computer and listen to the origin of the sound. Then again, I'm not sure it's actually making it into the sound card's output jack.

Either way, solution: USB DAC/audio interface.

Is the sound coming from the speakers? If so, I may know how to fix it. I had a similar problem and this worked for me:

Go into your sound control panel, select advanced controls, and mute all of the inputs and outputs except for master volume. If something stops working, sound-wise, un-mute the outputs until it works, but keep all others muted.

For example, I have to keep the master volume and one other (can't remember which) un-muted or the sound on my TV tuner card stops working.

I'm guessing that may do it.

Thanks for the advice guys. I tried lowering all sound levels other than master and wave but that did not fix it. I do have an antec case with power supply, so that is possibly the cause. I tried scrolling with the moniter off and it still makes the sound. Other than that, I will try opening it up this weekend to try and fix it. I may upgrade my soundcard anyway so hopefully that will help (mines pretty crappy right now).

It's your crappy soundcard.

It happened to me too once, I think when I was using SB Live Value.

Then I switched to less-crappy-but-yet-still-quite-crappy SB Audigy and the problem disappeared.

I occasionally get it with my Audiophile USB too. I'm not sure why it happens though...

 

[rwest1389]

I don't know much about computers as sources (i should probably put this on that forum) but is there a cheap way to reduce the background hiss? the sound quality of the soundcard isn't that bad (its SoundMax Integrated Digital HD Audio) but I think the problem is mainly interference. After looking at it I realized its onboard, so I can't switch slots. I don't want to pay too much because I only notice it on quiet parts of music. Would an amp reduce this background noise? Whats a good but cheap amp that you think would be good for me?

 

[kin0kin]

Noise level has to be fixed from the very fundamental source. An amp will not reduce the noise level, it will only increase it.

infinitesymphony, if it is the inductors that's making the noise, you don't have to pop open the casing to hear it. Just unplug your speaker from your sound card, lean your ear on the side of the chassis, behind the cpu, and you should hear the "zziiit ziiiitt" sound easily when you scroll your mouse. Of course, this has to be done in a quiet room. When I brought my pc back to the vendor I bought my mobo from, he couldn't hear anything as the ambient noise was loud (shop was in a mall) but still, I was able to convince him that something's wrong as I had him did the same thing and he could hear the buzzing noise, albeit more faint than what I'd hear in my room.

Good point. Now that you mention it, I've heard the humming when the speakers were completely off. I just wasn't sure if it was the motherboard or the power supply.
