There is disturbance in sound in speakers. Some kind of hissing noise comes from the speakers. But when i connected the speakers to laptop the sound was clear. Please tell what the problem is and what...


before anything update your sound drivers

Hissing in speakers is generally due to noise in the system somewhere getting amplified. There will always be a certain amount of noise, but what you can do is check to be sure your input gain is set on the high side. That helps ensure there's maximum signal to the (sadly, generally fixed) amount of background noise. Then adjust overall volume from the master.

The other thing is to try and isolate the cause of the noise by switching around between various end sources. So - If the noise is tehre when the DVD player is on, but not when it's off, then you know it's either the player or the interconnects to/from the player. Same on a computer - Try to mute and unmute various sources.

Onboard audio is typically not high quality, it's possibly your problem, it's also possible you've got a component in your system that's injecting more noise than usual (maybe something that's close to failing... or that isn't intended for consumer use). I have Realtek onboard audio on my HTPC but I replaced it with an Audigy card a couple years back, using the optical output to my audio rack keeps everything digital in the PC where you're most likely to get noise.

HISS from Numark DM1200 mixer. Not present in speakers (self powered) when mixer off. Using XLR cables with telescoping ground lifts on each line. Monster 3500 power filter. Ideas?


All interconnected equipment MUST be powered from the same receptacle or source. The XLR to the speakers should NOT have ground lift. The power for the mixer should come from where the speakers are and be routed alongside the XLR cables. All the other connected items should also be powered by the same source. The ground bounce within a building cannot only cause noise, but can rupture the input circuits of equipment. As an electrical engineer I don't know why manuals supplied with the equipment doesn't go into this more. The professionals at the big venues all know this as they have had to pay to get equipment repaired.

Now to get down to "hiss" once you get the other stuff straightened out, there are two things to know at the start: The first is that due to the statistical nature in electronics "noise and hiss" are among the laws of physics that we can't completely get around. The level of the hiss should NOT be objectionable however. The second thing is that proper level setup is important to minimize the effects of noise and hiss. You should be sending the levels to the powered speakers at near full line level into the line inouts, never mic inputs that some have. Using excess gain at the speakers will amplify any noise pickup on your audio lines. Next, at the mixer, try to keep all the level controls around 10 to 2 0'clock for rotaries and 70% for faders. Excess gain at certain stages will cause hiss to be objectionable.

Audio works, but lots of noise (hiss) in the audio

Visit the microsoft website - enter the details of your cam and check out the 'readme' link also 'breaking and known issues link'

Speakers have hissing noise coming out of them


Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.

Hissing Noise


this is a common problem and all you really can do is to turn the speakers off when you are not using them which is also good for your energy bill!!!

Logitech x530 hissing noise


I had the same problem for the longest time with my set of Logitech 540 5.1 speakers. Turns out the solution was pretty simple. All I did was open the Master Volume controller and mute the Microphone. Hissing went to zero. Sound is great now.

I have no sound coming from home theatre system


I would check see if you can hear any hissing coming from the speakers if there's no sound then check to see if this product has output protection fuses and if so see if they are in tact if this doesn't solve the problem you may have dead outputs. If there is hissing coming from the speakers check your audio source to make sure it is feeding sound to your amplifier without looking its hard to say in these case's there's a lot to go wrong
