External speakers won't work when plugged in to computer
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 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

Make sure the balance control in your VOLUME CONTROL icon in windows tray (by the clock) is centered....
There are sliders for each output/input and a balance control for each of these. uncentred they can switch off one channel.

Will the external drive work on another computer? Has the external drive been dropped, bumped, jarred? If it works on another computer, shut down the Win7 laptop, unplug, remove battery, remove the USB external plug, plug into AC, reboot, when it is finished, plug in USB.
There's not much you can do in the laptop itself since it's got only a small amplifier built in, and the speakers aren't meant to get very loud. You need to use external devices for more volume.
If you're by yourself, headphones work well. For watching with an audience, you're best off using external speakers which you can plug into the headphone jack. Then you can get as much volume as those speakers can deliver. Or, if you're at home or somewhere where a stereo system or home theater setup is available, you can connect the computer to an available input. You just need a cable with the appropriate plugs on each end.
Very few desktop computers have built-in speakers other than a small beeper on the motherboard, used for error codes at startup. You need some kind of external speakers which you plug in to the output jack on the computer's rear panel. Also, these need to be powered speakers, meaning they have a built-in amplifier. The computer's audio output signal is line level, and too low to drive speakers directly. You could plug in headphones, though, and listen to the computer that way until you get some speakers.
Open the Device Manager and uninstall the Audio Driver. Then click on scan for hardware changes. Now the Audio Driver will reinstall. Open the Sound recording and click on playback tab. Now select External Speaker as main speaker and check how it works
Plug in your external speakers then go to system preferences then sound when in the sound control panel go to the output tab and select the external speakers as the device for sound output and of course at the bottom of the control panel make sure that the mute check box is unchecked and turn up the volume. Hope this helps
EXTERNAL SPEAKERS: If your are plugging speakers into your headphone jack and they dont play, but you plug headphones into the same port and they work fine.. then it is the external speakers.
INTERNAL SPEAKERS: But if you are using the speakers in the laptop, then your speakers are probably bad. Try some software settings, but probly just bad speakers. Could also be that the speaker cord inside the laptop came unplugged from the motherboard. In which case you would have to take the laptop apart and plug it back into the motherboard.
if you want to get more sound from your laptop you need to buy external speakers. To get the best result when you are shopping for speakers look for some that take an external power source (AC adaptor that plugs into the wall)
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.
Nothing is wrong. Most computers automatically turn off the internal seakers after the external seakers are connected. Go to cntrol pannel and see what you can do under audio options or some such equivelent. Check back with more problems,
hope this helped/helps.
