New PC Speaker Feedback issue

[StuartCrees]

Hi,

I've just built a new PC and I'm getting horrendous feedback from my speakers.

I've updated the realtek drivers to the most recent but it made no difference.

I get minor feedback when I'm not doing anything and when I go into games, league of legends for example has a horrible screeching noise.

It can't be my speaker cable because I've plugged my phone into my speakers and it's absolutely fine. And also when I plug my headphones into my PC they're fine.. little bit stuck on what to do. Any ideas?

Also, I don't have a mic plugged in so it's nothing to do with that.

Thanks

Double check that your color-coded plug-ins all agree with user sheet from speaker maker.

If webcam, confirm mic is off.

If you have wired amplifier control in addition to the in system volume control, adjust to a minimal level and see if that helps.

Check speakers on another system - if problem continues thee, contact vendor for RMA.
