Sound won't differentiate between right and left speakers on headphones

Tablets are notorious for bad sound. I use a volume adjuster app to boost sound and use earphones.

Lots of possibilities. Most likely something is wrong with the headphone jacket. If a contact is lose or something came between it, it could block the throughput. Then you could have switch sound of, or even the speaker or amplifier is defect. Try a headphone to see if you hear something through there. When you get sound through the headphone, only a bad connection and a bad speaker are left. If the head phone does not work, it could be a bad connection or a defective amplifier.

Check the entry, where the headphone plug goes in, if nothing is in there. Just a speck of dust can disable the contacts, so the sound can't go to the internal speaker. If there is nothing wrong in the connector, try resetting the tablet and or restart the sound program you are using.

Does it have speakers or is it a device that only provides you with sound through a headphone socket? The sound properties usually tells you which it has, as external speaker of a headphone socket only.

Either the plus is not completely inserted (most likely) or a wire is loose or the earphones are damaged.

If the sound works on your Kindle Fire's speakers and will not cut off and reroute sound to headphones when you plug them in to the headphone jack port on the side of the Kindle. Try the following:

If you have a set of blu tooth headphones then enable blu tooth connection to a source of sound like, You Tube, Spotify iTunes etc. You will be able to hear sound on your blu tooth headphones this way. Turn of the blu tooth headphones, then try plugging in your regular wired headphones into the Kindle and reconnection should be achieved.

The bleep cold be just a bleep device separate from the speakers. It looks like a round piece of aluminum with a large dot of white solid past on it with a wire attached.
1st. make sure the volume is up all the way.
Then try using a headphone just to make sure the sound card is working.
If the headphones work then it should be a setting somewhere.
Sometime the switch that turns off the speakers when headphones are plugged in gets stuck, try plunging them in and unplugging them out while music is playing.
If they don't work the sound card may be blown but it is still possible it is not.
Also, try Keyboard shortcuts for mute and UN-mute.
Try going to control panel and bring up the sound app and try different options in there for mono and or what ever it has, you may find the answer there.
If the headphones work but nothing else works you can always plug external speakers in the headphone plug.

double check if the volume is on mute there is a certain icon from your keyboard that indicate volume. try holding Fn key then press that volume button to unmute it. make sure also that ther eare no headphone connected as it will disable sound if you are expecting it from speakers. you may also try checking the driver status if you need to reinstall it or update it. simply go to control panel > system > hardware tab > device manager to check audio device there, if the icon has yellow marking on it then that is the problem you just need to reinstall or update the driver for audio by either using the driver disc that came with the system or downloading it from the manufaturers website

Make sure that the correct playback device is set as default in sound properties.
If all is well there then you could try a pair of headphones to see if the sound is working.
If headphones work ok then it is down to your built in speakers, not much you can do unfortunatly unless you are still under warentee

I have the same problem and just figured it out. Go to the sound settings and set the earphones as the default. I just did this and it now works.
