Question about Philips MMS 321 Computer Speakers
Common humming sounds from computer sound systems stem from the follwing:
1) Interferance with other electrical componants / devices
Solution: EMF / Radiostatic shielding may provide the solution
2) Defective componants
solution: try the hardware in another PC, if it still hums, your board / plug-in compants may be defective.
3) Jack(s) - Headphones / speakers have loose connection
Make sure everything is plugged in securely, and your jacks have not been damaged, also make sure you are plugged into the correct ports.
4) Microphone boost / auxiliary settings
check your sound settings, disable any ports you aren't using. Line-in, Aux, CD-rom, Digital Input.. if they aren't being used, they may be creating "whte" static in the lines. Muting them, or disableing them in the sound settings for your device may provide the solution..
5) It has been known to happen that certain CPU / Case / Power supply fans emmit a sonic frequency through the speakers due to EMF expulsions from the electro-magnetic motor. This is rare, but is possible, Disable the case fan to determin if it's the culprit, swap power supply, or CPU fan to determin if they are the issue.
WARNING: Never run your PC without the CPU fan in full operation, Never run the PC without your Power Supplies fan in full operation: This can lead to DAMAGE to your PC.
On a personal note: My card has several different ports, make sure you are plugged into the correct port, and muting the Aux cleared the humming in my computer's sound system.

This can be caused by several diffrent things. Most of the time it has to do with electrical interference. **** as being placed directly near your monitor, the computer itself, a tv, a radio, or any other appliance that uses a lot of power.
the 2nd thing that can cause this issue is that the speaker is not hooked up properly into your computer. Double check that it is all the way pushed in.
The last and final solution. Sorry friend but you either blew your speakers, or they came to you already defected.

Try moving them away from the screen, or if possible using another power supply. (check voltage . polarity!)
