Have your sound card updated from it's manufacturers website. This should do the trick and this should be pretty easy for you.

Hi, what causes hums from speaker is when there is no ground shield from either the power supply or from the cable you plugged into the socket from the power supply.

So you will need to check that out and replace untrusted cables for connection..

If after doing this troubleshooting exercise, you will now need to test the speaker with another set to be sure the humming sound is not coming from there.

I guess that will Do.

Have a nice day...

Humming sound in subwoofer after it's been playing for a while


It sounds like you are describing an earth loop problem. I won't go into detail in this post, but try an isolation test first. disconnect everything from the reciever except the sub and try connecting say a BATTERY powered mp3 player or cd player to minimise connections to the electrical mains earth. you could also isolate things by taking your sub to a friend's house and trying it on their system.
If it is an earth loop use a process of elimination to find out which two pieces of equipment causes the earth loop. then apply filtering.
you can buy earth loop isolation transformers for about AU$26 and I've used one on my sub myself. Theyhave RCA (phono)plugs on each end and they connect inline with the signal cable to the sub amp.

as for the thumping sound it might be the speaker protection circuitry cutting off the amp to protect the subwoofer speaker from damaged. This might be triggered if the earth loop sound is causing the sub amp to overload and clip.

Failing this there might be a dried out overheated electro capacitor in the amp circuit causing the hum. Hav a chat to your local electronics person, who should be able to spot it!
Hope this puts you on the right track
Happy Hunting!

Humming speakers


If you disconnect the signal leads and the hum is away, it's probably a groundloop problem, or your equipment is generating the hum.
If it does not go away, the amps are defective

Humminf sound from subwoofer


Most humming sounds in speakers is due to electrical currents or wifi signals nearby the speakers.

Do you have any electrical cables near the speakers? Do you have any wifi device near the speakers?

If so move them out/away and see if there is any difference.

Humming


Hi,

More often than not, the humming sound on any electronic device is brought about by the AC side of the power supply not only of the device itself but also all other equipment it is attached to. In your particular case, it maybe introduced into the system from:
  • (coaxial) cable TV leadin;
  • connections of DVD, VCR, game consoles and others;
  • electrical noise from lamp dimmers, lights with electronic ballasts, wireless phones.
It is interesting to note, that the noise could be from other appliances plug in the same circuit as the TV, you of course could try plugging it into another outlet or branch. In some instances, you could even try filtered regulators similar to those used by desktop computers.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
