One of my computer speakers buzz

by guitarkiss / November 2, 2009 6:28 AM PST

A few months ago I bought a set of Sony SRS D21 computer speakers. At first there were no problems, but a few days ago I noticed a soft (and annoying!!!) buzzing sound coming from the right speaker. When I increase or decreace the volume of the speakers or the computer it has no effect. The music volume changes, but the buzzing remains the same, so when I play music softly, I hear the buzz coming through. When I unplug the speakers from the computer the buzz is still there. I tried pluggung the power plug into a different wall socket, but that didn't help either. What could be causing this? I know it can't be my sound card. And if it is some kind of interference, why is it only effecting the right speaker?

When I unplug the speakers...the buzz is stil there???
by Grif Thomas Forum moderator / November 2, 2009 7:11 AM PST

If the speakers are unplugged from the computer and no sound can now go through them, how does the speaker "buzz"?

That aside, normal fixes for speaker buzzes are the same whether with computers or with other sound systems.. If you can repair the buzzing portion of the speaker, such as a torn cover/screen, dust in the speaker cones, or bad connection to the speaker box, do so.. If you can't repair such, replace the speaker.

Hope this helps.

They are powered speakers

Thanks for the reply.
Perhaps I should have mentioned that they are powered speakers (they need to be plugged into a power supply in order to work, and also into the computer). The speaker cones themselves are not damaged, at least I don't think so, because there is no distortion when I turn the volume up. And the buzz is there regardless of whether I play music or not. If there is power to them, the buzz is there. But I will take a proper look, just in case. I'll also look for dirt, bad connection, etc. Thanks.

Bad Power Can Also Cause A Buzz
by Grif Thomas Forum moderator / November 3, 2009 4:58 AM PST

Lots of speaker systems "hum" and a bad speaker setup can vibrate a lot.. Basically, if the speakers don't work, then test your system by swapping in a known good speaker system.. If the second system works fine, then it's probably time to get a new speaker setup.

Hope this helps.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
