Feedback sound


If moving the microphone doesn't work then suspect "microphonics" where a loose electronics component is vibrating and acting as a microphone. Could be cable. Unplug all microphone cables, still feedback? Right click speaker icon, sound properties, temporarily disable computer sound input devices. If still feedback then analog section of sound card (or motherboard sound chip) or your speaker system.

No sound from computer


Check the speaker cable connected properly in the back of the computer. If you have recenly unplugged the speakers , chances may be you have it plugged in wrong place. Green output is the one for the speakers in most computers.
This is not the case , problem would have been in the speakers or the computer hardware. Try connecting another speakers and see if that would work. If it still doesn't work replace the sound card on the computer.

My speakers started buzzing and making a horrible noise during the night. I had to unplug them to get it to stop. What's going on?


Feedback. Check the wires, might have a bad connection. Wiggle them around and see if the buzz sound stops or changes. If that happens, its usually that wire. Good Luck.

Loud noise feedback in subwoofer


Try another boosted speaker set. Then check.
Something is probably wrong in the speakers, not worth fixing...they are pretty cheap to buy.

No sound through external speakers


Although some monitors have built in speakers, most people have stand alone speakers. If the old monitor had built in speakers and now it is unplugged you won't hear sound. Even if the speaker cable is still plugged into the sound output on the back of your computer, the monitor must be plugged into an electrical outlet to have power.

I'd recommend buying a new set of external speakers if this is the situation.

If you never had speakers built into the monitor then normally changing monitors would make no difference whatever. The only explanation that makes sense under those conditions is that in the process of replacing the monitor, you dislodged the speaker jack from the sound output on the back of the computer.

Make sure your external speakers have electrical power plugged in, the power is on (green light on at least one speaker lights up) and the volume on the speakers is at least half way up.

Unplug the speaker from whatever hole it is plugged into and plug it firmly back in and test sound.

If still no sound other than some static on the speakers, try every single hole on the back of the computer that the jack will fit properly and test for sound.

Let me know if you have further questions.

My subwoofer for my Logeitech Z-5300e THX 5.1 Surround Speakers omits a loud hum whenever the system is activated. How can I get rid of this?


The sound you are discribing is indicative of a short in the audio cable coming from your amp to the woofer. it doesn't mean that you have to replace a cable, but it could mean that one is loose. I would first try to turn on the unit and then start unpluging each speaker from the back one at a time. If the sound stops then you know that the hum is caused by the last speaker cable you pulled out. It is possible that you could make a temporary fix by twisting the cable back and forth where it connects into the back of each speaker. (Though this would only be a temp fix.) Because these cables are hard soldierd into the the actual speaker, there is no way for a person to simply replace the problem cable.

The other possible problem could be with the cables coming from the computer. You might simply have the cables in the wrong inputs. They should be color coordinated. Yellow in yellow, etc. Or with the system on, unplug these cables one at a time to find the problem cable.

If non of these work, I would bring it back to the store for a replacement system if still under warranty.
