Speakers not working

try swapping the speakers around if the problem still persists either the speaker is faulty or
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
or you might have to clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
other than that you might have a warranty issue
hope this helps

It could be your receiver but you can try seeing if the Woofer has a input knob at the back, maybe this down, or maybe.if possible turn down the amount going to the woofer with your receiver.

Groung hum is usually caused by another 60 cycle interfearance. The two case grounds are not sharing a common ground. Use a 2-prong adapter on the speaker power cord, thus isolating the ground to the speaker.

Sometimes you can take an extra audio cord and connect (a not used connector) from the bass speaker to the computer, just so it will have an additional ground.

You have a possible fault in your wiring of the speakers, the Phases of the speakers are crossed over resulting in cancelling of the low frequency- bass frequency. Hence please reconnect the speakers front and rear with the positive/ negative to the corresponding positive and negative of the speakers.If you are unable to fix the marking of the polarity use 1.5 Volt cell to connect to the speakers , if the speaker moves up the terminal on the positve of battery is positive. reconnect and test with a good bass song for result. Helpful. Good day

One or more of the wires may have a break. If you can get similar wires from an electronic shop, you should try that first. It's also possible that the internal electronics in the sub-woofer (the volume,bass,treble controls and the related electronics) developed a fault. In that case, only a service technician can repair it.

Hope that helps,

You can't use the speaker with your computer apart from the monitor because of that plug. The powered woofer was made to work with the monitor and needs to be connected to the monitor to get power, input signal and volume control. If you want a powered subwoofer for your laptop you will need to purchase a new speaker system.

the wires inside may be the problem, or sometimes it is from it`s mainboard, ask an electrician to take a look inside

I'm having the same problem, bass will cut out randomly everything is plugged in correctly if you bump the subwoofer it seems to come back on for a bit then back off, did you ever find a solution for this?

you may have a short in the wiring
you can always open up the bass box and look to see if the wiring is a little loose.
if you know how to use soldering you may be able to fix it.
if not you may be able to just tape it in place

i know what your problem is...you have the realteck device right??there's some options in the device you can change and everything works
