Stereo Speaker troubleshooting

It's on a laptop: both small laptop speakers work, but when i plug in external speakers or headphones in the headphone jack then the sound only comes out of the Left one (or nothing at all). My dell guarantee has expired so they wouldn't help me out. What else can i do and at what cost? and whats the problem? sound card? it happened right after i tried plugging an amplifier in that same audio jack. probably blew it up somehow. I hear it is hard to replace laptop sound cards though...
ps: i have already verified that the plug is fully inserted.+ it is not a volume control issue since both internal laptop speakers work when nothing is plugged in. + i have already verified that the headphones/speakers i was using are fully functional and stereo. they do not need an seperate power source. I know that the speakers aren't broken since they work on other mp3 players. and the balance is right since when nothing is plugged in the audio jack, the sound comes out of both internal speakers.

    crichner,

    by that, i meant that i was trying to get the mp3 from the computer to play on my amplifier, and i guess they both (laptop and amp) were turned on when i made the connection, so that was when something probably happened. So yes i plugged in an output of another device in the headphone jack, as i was trying to get the amp to act as a speaker. It worked before that, and stopped working right after that.

    I woudl sprculate that the female jack on your computer is defective as to picking up the other imput. If the jack is open inside,maybe you could lightly bend back the contact point on the jack which i thibk you mayhave streched too much for the male plug to touch?.

    Please explain "i tried plugging an amplifier in that same audio jack".
    Do you mean you plugged in an output from another device into the headphone jack?
    Did it work before that?
    There are no laptop sound "cards" it's part of the motherboard.

It sounds like the audio jack itself has internal damage. Depending on how it is mounted on your laptop case, or possibly on an internal circuit board inside the laptop; it might be possible to repair the jack or replace with a new 1/8" audio jack. Some soldering skill may be required after disassembling the laptop and getting access to the jack.

Cant get to play music without headphoes


Most modern computers come with internal speakers already installed, especially laptop computers.
These speakers may be sufficient if you are performing typical computer tasks, but when you play computer games, listen to music or watch movies on your computer, you may want louder and more vibrant sound.
You can achieve this by installing external speakers or headphones. These can be connected to your computer through the speaker or USB ports included on your computer.

Plug in the speakers or headphones.
If the speakers or headphones use a stereo plug, insert the plug into the speaker/headphone port normally located on the side or front of your computer.
This port is often color-coded green. If the equipment is connected using USB, locate a free USB port.
Some external speakers will also need to be plugged into a power outlet in the wall or your surge protector.
This may be all you need to do to get the speakers or headphones to work. If they do not, continue to the next step.
Open the audio settings on your computer.
From the Windows Start menu, open the Control Panel. Here you will find audio and sound settings.
Click the heading to see your sound and audio options.
Choose "Manage audio devices" in Windows 7.


Find your Playback device.
In the Playback tab, you can select your speakers and set them as the default for your system.
If you do not see your speakers or headphones, they have not been installed properly. Disconnect and reconnect them to see if it corrects the problem.

Configure your settings.
Select your device from the list and click "Configure" to test your settings.
You can adjust the volume by using the volume slider on your computer's task bar or using external controls on the speakers or headphones.

I cant get sound on my viewsonic va520


You need to add some information - what is the source for the video that you are viewing on the VA520? The VA520 has no speakers in it. If it is a desktop computer, look on the back of the computer for a green 3.5 mm stereo audio port. This is your speaker out connection. Plug in any set of computer speakers or headphones. (Computer speakers may require a USB connection or to be plugged into an AC outlet to power the speakers.) You can find cheap speakers for under $20; good speakers will be more expensive. With a laptop or some desktops, you'll find a headphone jack on the front of the computer. (This will be labeled with a small picture of a set of headphones.) The headphone jack is also a 3.5 mm stereo port.

I hope this helps.

(laptops usually have internal speakers; most desktops do not have any internal speaker anymore. If you have headphones with RCA audio plugs, you can use a RCA F/F to 3.5 mm M audio adapter to use them with the computer. A stereo system may not work with a computer.)

How can I connect external speakers to my toshiba laptop C650D? Thank You.


Either with a stereo headphone plug and into and external amplifier or you could use a PC speaker set up. That will plug into the headphone socket also.
Hope this helps.

No sound from speakers.


Hi...
On some stereo gear the headphone jack interrupts the speaker connection when the headphones are in. you "might" have something broken in the headphone jack which is keeping the speakers from turning on.
Is there a MUTE switch on the unit?
Or an "External speaker off" thingy in the menu?

Compaq C740TU speaker does not deactivates if external speakers are connetced


The internal speakers should automatically be disconnected by inserting a 3.5mm jack plug in the audio out socket. It may be that your headphones or external speakers are using a 2.5mm jack which is too small to operate the switches in the audio out socket. Purchase a 3.5mm jack plug [cheap] and plug this in if it disconnects the laptops internal speakers then you need to connect accesories with the correct size plug.

EXTERNAL SPEAKERS ARE AS LOUD AS THE HEADPHONES WHY?


The ability to turn off the external speakers of the radio being plugged into has to do with the capabilities of the radio itself, not the headphones. Most radios will automatically disable any built-in speakers when you plug headphones in but yours may require an extra step. Check your radio manual to see if it has a switch that can do this.
