Sometimes empty/unplugged channels introduce noise to the amplifier. You can always try to connect all of the input channels to some external mobile phone/mp3 player, etc. and then set these equipments to the minimum possible volume (mute if possible). This should remove the "atmospheric" audio noise.

Vox vt40+


that is because it is two different output channels. eventually you will blow the speaker or your amp. It wasn't designed to handle the impedance of an external speaker through the stereo
headphone jack. Are you sure that your speaker is hooked up or plugged in?

Ac adaptor crackling thru external speakers


Allan, It sounds like you have what is called a ground loop. A ground loop can occur when two pieces of equipment are connected together through a home or buildings safety ground through the same power source. For instance, your PC is connected to a power source through the AC adapter or plug, and your external powered speakers are receiving power from the same power source. The surrounding cables as well as the AC adapter(s) can act like an antenna. This will cause a low hum or crackling that would be audible through the speakers or headphones.

You may want to try plugging all components into a power strip so they are all on the same circuit. You may also want to be sure that the AC adapter cables are not not laying or running across other electrical components plugged into a different socket.

If you get the same hum through your headphones check to see if the headphones were manufactured with shielded cabling. A shielded cable is made with a wire mesh around the outside that helps reduce electrical noise. Hope this helps a little. Thanks!

I dont have sound in my pc.i dont know where to fix my problem


If you sue external speakers or headphones, follow these instructions. If you have a notebook computer & are using the onboard speakers, skip to the *Windows section below.

You can start by checking your speakers, if any. Make sure they are powered on and functional. You may also want to test there speakers on a different computer just to make sure.

If the speakers work on a different computer but YOURS still does not have sound, try a known-working set of headphones. Make sure the jack is seated correctly as it may be loose.

*Windows:
Check the volume controls on in Windows. If windows does not have any volume controls, then chances are, the sound drivers are not installed. Check your computer manual to find out what model it is, then visit the manufacturer's website to download the appropriate drivers and software for the sound card.

Note that if you have used external speakers or headphones anytime before this issue started, you may have to re-plug the device & unplug it again & allow Windows to detect that it's unplugged (for HD-capable audio devices in Windows Vista or 7).

If you do have HD audio in Windows Vista or 7, right-click on the volume control in the notification tray on the bottom-right corner of your screen and select "Playback devices"...

... then make sure you choose the appropriate output device (whatever it is that you actually use: Speakers, headphones, HDTV output, etc).

My hp laptops volume sounds really distorted im not sure why?


The first thing to check is to ensure you have the most updated drivers for your computer and the audio section. If that is okay, then it may be that the speakers are busted. If you have a set of headphones, you can plug them in and if the sound is okay, then the problem is probably your speakers.

My view sonic monitor has no sound


Troubleshooting Sound Issues Verify that the audio cable is connected to the AUDIO OUT or LINE OUT output on the Sound Card and plugged into the AUDIO IN or LINE IN of the Monitor.   Make sure there are no cables connected to the Headphone Jack (located next to the AUDIO IN port) on the monitor. If there is, please disconnect that cable and try the speakers again. Connecting a cable to the Headphone Jack disables the speakers. If there is no cable connected into the Headphone Jack, test a pair of headphones into that jack to see if you can hear sound out of the headphones. If you are able to hear sound out of the headphones, disconnect the headphones and try the speakers again.   Verify that the Mute on the monitor is not on or the Volume is not turned down.    Verify that the Mute on the computer is not on or the Volume is not turned down.<    If there is still no audio from the monitor's speakers, connect the Audio cable to another audio source like a portable CD player or tape player headphone output. If audio can be heard through the monitor's speakers, then there may be an issue with the computers sound card.    Connect another set of computer speakers (if available) or headphones to the AUDIO OUT or LINE OUT output on the Sound Card. If NO audio can be heard then there is an issue with the sound card. Verify with the computer's manufacturer for additional assistance.   LCD TVs Troubleshooting No Sound from a LCD TV No Sound when using RGB (when connected to a PC) Confirm the audio cable is plugged into the Audio in on the LCD TV and the audio out on the computer. Note: On the N1700W use the GREEN mini-jack; on this model Audio is SHARED between DVI and RGB, there is only 1 audio channel for data connections. The N1700w is designed to take a 1.0v RMS audio signal for optimal sound quality.   Confirm that both the LCD TV Mute and Windows Mute are off.

Hello, When I connect my headset on my laptop Asus a7sv I get sound but no sound from the speakers. I have Windows Vista en I downloaded the original driver from the asus website. I tried everything....


Most headphone jacks operate as you describe. There is a switch built into the jack that diverts the audio from the speakers to the headphones for "private listening". If it didn't work this way, there would be no way that you could enjoy an audio track or other program with others having to hearing it, too.

You could get around this problem by using an external speaker set and a "splitter cable".
moz-screenshot.pngfaaa714.jpg
A splitter cable is simply a three ended cable like the one pictured above. The first end has a male plug that matches the jack on your computer - likely a stereo mini plug. The other two ends are usually the same; but the female version. You would plug the splitter into the SPEAKER jack and the laptop speakers would be silenced. Next, you would plug the the external speakers into one of the splitter jacks and then your headset would plug into the remaining splitter jack. You would connect the microphone plug into the MIC jack on the laptop.

You'll have to tinker with the sound levels as there will be feedback issues - depending on how close and loud the speakers are to the headset microphone.

Please rate this reply - and good luck!

Right headphone break & malfunction (sound keeps breaking up)


What you have is a break in the cable, you can track it down by flexing the cable in different places till it acts up. Now once you have done that, you can determine the best course of action, I will come back to this shortly.
The distortion sounds to me like one of the earth wires inside the cable or at the plug end is off or broke. If it sounds spaced out or tinny then for certain you have an earth break.
OK bearing in mind the headset break, it now depends on where the cable break is. If it is near the plug end then you could cutt the offending section off and fit a new plug. The same in the middle (you would simply need an extension cable to make it longer). At the top near the headphones and you would need a new cable and have to go into the headphones to fit it, increasing the risk of further damage to the repair etc.
If you are good with a soldering iron you can do the first two options, however I wouldn't advise the third, due to the damage.
It all depends on how you feel about the style of the headphones, for you could replace the whole headsett and cable, but keep the high quality speakers. All you need do is find a cheap pair of headphones with the same size speakers as yours. Then all you need do is take both old and new speakers out and fit the old speakers in the new case. They won't look as good but they sound will be the same.
If you go for opition one or two and don't know how to put a new plug on just let me know.
If you go for the opition to remove the old speakers, you will need to remove the ear pads and any foam and then you should see access screws to get at the speakers (on both shells).

My behringer djx700 5 channel pro dj seems to have a feedback problem even when nothing's plugged in to it cant figure it out.


Hello,

It doesn't seem like a typical "feedback" problem, as feeback is produced by over modulation between the amplifier and the source - usually a pickup or microphone. It may be your cables to your amplifier are bad, or the actual line out jack(s) may have gone bad. If it is more of a humming sound rather than feedback, that is most likely your issue. If you have additional patch cables, switch out the existing ones, and see if that ends it. If not, it is possibly the jack(s).

You have a headphone jack on the Behringer, though you did not say if the problem arises through the headphones or an external amplifier. If you get the noise in the headphones, when no patch cords or a mic is attached, then the problem you should look at is your headphones or the headphone jack. You can narrow the problem down by using an external ampifier and see if you still have the "feedback" sound. if not, it's in the headphones or headphone jack.

Please try and provide more information for this question if we are unable to track the problem with these suggestions. As we do try very hard to center in on customer's problems, we do ask to provide as much information as possible, so that we can facilitate your resonse more effeciently.

Thank you for using FixYa.

Low sound in headphone


I would say it is because the unit does not have a built in amplifier. The speakers are powered PC speakers of studio monitors I am guessing. Try plugging the headphones into the headphone jack of the speakers if they have a headphone jack or try a set of powered headphones out of the Edirol and see if it helps.

That should remedy the problem.
