Humming noise from speakers

Hi,

I am getting humming noise from my computer speakers whenever i plug the power cord. I tried disconnecting the jack from the CPU and also switching off the speakers. But nothing worked. When i switch off the power supply the noise stops. Can anyone please suggest me a way to solve this problem?

Thanks

You've done your homework on eliminating potential external sources so one of the few things left is a failed filter capacitor in the power supply of the unit.
'Hum' is one of the most common signs of this.
If a capacitor fails catastrophically, there are normally visible signs of it.
If you are adventurous, you can invade the subwoofer box where the supply and amplifier are probably situated and look at cylindrical parts in the area closest to the AC input.
The supply will be in whatever case to which the power cord is attached and the bigger box is the most likely candidate.
Capacitors of this kind can be in size from a 1/4 of an inch to 1 1/2" in diameter, have a plastic sleeve around them that is normally open at the top where the aluminum of the case is visible and they are mostly installed vertically in the board.
These often (but not always) have 3 scored lines radiating from the center.
Check around each of these for any signs of crusty deposits and on their tops, look for signs that the top has bulged.
If you find any looking like that, they are probably defective.
There are values on the sleeve that will be in 'uF' and voltages expressed in DC; i.e. one that bears 47uF/16VDC needs to be replaced with that same value.
If you make it that far, you will need only few tools but a decent soldering iron to remove the failed part and pay attention (marking is best) where the + and - leads go since they will fail and make a mess if improperly polarized.

If you do not see any with the signs of failure described, the only recourse is to find a tech with a capacitance meter necessary to find the failed part(s).

Since the cost of repair by any shop would exceed the replacement cost of a new set, you may end up contributing to a landfill.

Humming sound cumin from my creative inspire 4.1 woofer


Make sure that you've fully pushed in the jack to the sound card.....maybe you've not connected the jack into the correct socket on your soundcard as there are usually 3 identical sockets...but only 1 is the correct one. Sometimes colour-coded green. Try it in each one in turn. If you have headphones, try plugging them in as you will hear sound in them when you've got the correct socket!

When i turn on the power for my speakers it hums like crazy


do they hum when you unplug the audio jack from the PC?
If they stop humming when disconnected the problem will be down to a bad earth connection on the motherboard, or a failing power supply (rectifier circuit)
Humming is normally a result of voltage potential and the 50hz frequency in the mains.

Hope this helps

Sounds like a problem in the speakers' internal power supply, maybe a faulty capacitor. Speakers need to be looked at by a technician, or replaced with a new set.

Two speakers hum noise


Very doubtful that hum issue is ground potential difference from multiple power outlets as power cord is not grounding type (it is transformer isolated). I do agree that it is good practice to connect all audio equipment to common power strip though, especially with pro sound. Check the audio cords connecting your speakers to the coumputer sound card: 1) Make sure they are connected to the correct jacks and plugged in all the way, 2) wipe the connectors off with a clean paper towel wetted with a smidge of WD-40, 3) replace cords if all else fails. I have also seen solder joints fail on the power supply capacitors (due to vibration) causing hum -- but leave this repair to an electronics technician due to dangerous voltages.

I HAVE A Z-2300 NO SOUND


Is it plugged in with a 3.5 millimeter jack? If it is, pull it out of the computer and press you thumb on the tip, if no humming noise comes out, your speakers are probably blown.

However, if a humming noise does come out. Please check to make sure the volume on the computer is turned up/unmuted, the software's volume is turned up/unmuted, your sound card driver is installed (Right-Click "My Computer" -> left click on properties -> Click on the Hardware tab -> click on "Device Manager" -> Click the "+" next to "Sound, video and game controllers" and make sure there is no Red "X"'s or yellow "!"'s.

If you do get a hum, and you do have everything set up right in Windows, try a different pair of speakers or head phones. Your sound card might be fried.

Also, make sure you're plugging the speakers into the correct port on the computer (It's usually a washed out green port"

Static noise coming out of speakers


What sort of computer do you have? Is it a laptop or desktop? Many laptops have this problem and it is quite widespread in laptops. The crackling or humming noise could be a result of interference from the mains power signal.

If it's a laptop, try running it on battery alone (take out the mains power cord). My laptop has this kind of noise in speakers when running on mains electrical supply, but it goes away like magic when I run it on battery.

A more long-term solution is to buy a 'Ground Loop Isolator' and insert it between your computer and the speakers/earphones. They are quite cheap and you could get it for under £10. It removes all static noise and you'll hear crystal clear sound.

Loud humming coming from subwoofer


This can be caused due to an increase in local interference. The hum is decreased when you plug in the satellites because the interference is spread over a longer area. You may notice that speakers tend to hum around things like cell phones and power outlets. To see if this is the case, move the speakers to another part of the room if you can, slide the desk around, plug the computer in at another room, something like this. If the hum gets louder or quieter, it is interference at your new place. This can be solved by finding a new area to set up your computer stuff at. Since it's mostly the subwoofer, try elevating it off the ground, there may be a power main running under the floor.
