My speakers are buzzing.


Passive speakers don't buzz in the absence of a signal that makes them buzz. Look for a single source doing it, specific cabling loose, power cords near signal wires.

I have bought an optical fibre cable to connect from my jamo a305 to my new sony nx810 tv and im getting a buzzing sound, there are 2 optical fibre outputs on the back of the amp, which one do i connect it...


Have you looked at the manuals?

A TV won't run external speakers directly. Besides, the TV-related audio should originate at, say, the cable Box, and go straight to your (presumed) AV receiver for the best possible decoding and reproduction.


Buzzing is an analog phenomenon and is NOT carried by optical cable in any case.

Buzzing is usally AC line noise leaking into an un-shielded cable somewhere or a floating ground. If the AC plug is reversible, try that. Sometimes the buzz is from an attached device. Make sure all audio cables are plugged in tightly at each end and routed away from or at right angles to any power cords and away from other sources of strong magnetic fields like TV's. I've also seen variable track lights induce noise but it's usually minor.

Try rotating the power cord in the wall outlet.

If it still buzzes with no cables or anything external attached there's an internal problem.

Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

Reverse the cables Left to Right to see if it stays with the cable or the input channel. Follow it back to the source, isolating in the same manner. Eventually you will find the entrance point of the hum. Frequently a cable's ground will oxidize over time and simply removing and reattaching the cable with a twisting motion will re-establish the shield.

I recently connected my satellite reciever to my


Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

Speakers buzz with no sound


Is this only with CD, only with THAT CD, or with nothing in particular selected or playing?

Check all connections for tightness as bad cable shield connections will let emitted noise into the system. Ditto for signal or speaker cables routed near power cables, TV's, other electrical sources.

Sometimews reversing the AC power cord polarity can resolve buzz/hum.

I dont know how to set it up. I put the green cord in the computer..but theres one black cord and i dont know what to do with it.


There should be ONE stereo miniplug to be connected to the headphones output of the computer, and one power supply plug to be connected to the AC adapter. These speakers do need a power supply, since they have an internal amplifier.

Speaker buzzing at random


It sounds like the socket on your computer is becoming worn or has a loose solder joint.

If you feel comfortable with a fine tipped soldering iron and stripping your computer down I would take a look there first.

Also check the power supply for the speakers to make sure it is not getting too hot.

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.
