Onboard sound= hum from HDD/ mouse movement etc.?

UOcUK Poopscoop · 9 Feb 2006 at 23:19

Got an Asrock Dual Sata with onboard sound (realtek ac97)

Only noticed the noise since fitting a 7800GT but it may of been there before but I *think* it wasn't.

It's livable, but a slight annoyance.

Is it likely to be just the onboard sound causing this humming? I know some older gen Nvidia cards could cause this too.

Could a cheap Audigy be likey to cure the problem?

I am assuming the onboard sound is just picking up electrical noise from other activity on the mobo. :confused:

If you mean you get noise when you move the mouse then i get it too, and and have had it for 2 years without a fix. Never bought a new soundcard though.

I get the hum/buzz when i move my mouse/scroll etc. And its an Audigy 2 Platinum.

The mouse is an old logitech USB optical one...I updated the drivers and it improved (reduced the sound when the mouse is moved) and although the noise is still there, it isnt as noticeable as before.

I never found a solution to it...i just gotta live with it. If you get it sorted, let us know!

I used to get that on my old computer (p4 3ghz, asrock board, 6800nu), a sort of clicking whenever you scroll down the page? Seems like it is coming from nowhere ><
Doesnt do it on this computer though, thankfully

Thats just rang bells off something i read a good few months ago.

You dont have a Logitech mouse by any chance? Im pretty sure i read its a common problem with them.

Ouch, so even a new sound card may not help?

It's kind of a humming noise whenever the PC does anything.

Scrolling down a page, a flash anim, HDD being accessed etc.

Being from an electronic background it is definitely some sort of electrical interference from the sound of it.

Try disabling the phone line input. It's enabled by default. My laptop with a Realtek also makes noises when you move the trackerpad. Totally silent after that.

Hey mate, you have lead me to an almost total cure.

I had already disabled Line In as Iwondered if that may of been the problem, no joy.

Your post lead me back to the Line In control again though....

I went back and un muted it and then played around with the slider for it.

Would you believe that using the slider you can actually "tune" the noise out!!

Too high a volume and it comes back..too low or muted and it comes back!!

Fine "tuning" the slider has got it to the point where I now have to almost strain to hear it!

Ta for sending me the right way on this one bud!

I'm sure this won't work for most people but got to be worth a try for anyone else too.

Try the "phone line" input- it's not muted by default, also mute any other unused analogue inputs. You will need to add them to mixer. Add them all, mute each one by one and see the effect. Straight away when I mute "phone" total silence.

At the end of the day though you will never get rid of it totally with onboard.. I just gave in and installed a pci card from another compter.. No hum at all.
