Whining noise from speakers

by Teryss / November 20, 2007 2:43 PM PST

Today I put in a wireless internet card, the internet works fine, but the card seems to be causing a problem with my audio device. When the wireless card is in my PC I get this odd static and screeching noise from my speakers/headphones. I know the wireless card is causing it because if I take it out the noise goes away. There are 3 open PCI slots between the two, I thought putting some space between them may help, but I was wrong, and I honestly have no idea what else to try. Any help would be greatly appreciated. Thanks!

If it matters, I'm running Winxp, the wireless card is Netgear wireless-g PCI adapter- WG311v3, and the audio device is a CMI8738/C3DX PCI Audio Device.

RF interference sounds likely

Does the volume of the noise increase when you turn up the speakers? If so, the sound card could be picking it up. If not, your speakers are probably doing so. You can try taking the wireless card back and trying another brand.

I suggest

I agree with the other poster as "RF" being the possible source of noise. Afterall, the wireless card uses a signal(RF) to work. If possible try another slot or relocate speakers. But, since this also going thru the headphones, you simply are too close to the RF noise. As you say, the card seems to be the source, then try another brand or replace and/or move the audio card or both. If these are actually one slot next to the other, oh yeah move them apart. If the audio is build-in, move only the wireless card.
