I had a similar problem. First of all, ensure that your headphones are connected to the right jack plug (the green one).
Go to the control panel, then to hardware and sound, then sound. You should see something called manage audio devices. Plug in your headphones and see if they show up. select your headphones at the bottom it will say set as default, select this option.
If they don't, then either your drivers (these things will tell your computer what kind of hardware it has and how to use it) are missing or the the headphone jack itself has failed. Lets say it is in fact your drivers that are missing, then all you need to do is either use windows update(it will detect many of your missing drivers) or go to the manufacturers website and look for them there(usually they will have a tab somewhere on the home page that will say something about support or downloads). And also try different headphones, those could have messed up as well.
Now lets say that you do see the headphones show up as an audio device. Then all you need to do is set them as the default and that should fix your problem. Though I will say that I currently have a problem with switching between the two. Once I start a program such as media player, it will stick with the current default audio device.
dude I know how to fix it I had this exact problem!!!
Go to Control Pannel
click on Hardware and Sound
click on Sound
then you devices should come up ; speakers, Digital Audio, and headphones
plug your headphones in
then select headphones
at the bottom it will say set as default
then when you disconnect your headphones it automatically switches to the speakers and when you plug them back in it automatically will switch to headphones!!
there ya go man!!!
it took me like 2 hours to figure that out lol.. hope I was helpful
RealTek HD Sound Problem
This works for my 7540 Acer laptop w/ built in Speakers and SoundCard
a) The Laptop has 3 Ports on the side- Pink,Green,Black
Pink Port is LineIn for an external device player jack
Green Port is LineIn for the Microphone jack
Black Port is LineOut for Headset or External Speakers jack
Plug the Green jack on Headphone - into the Black Port on the laptop.
b) Go to Control Panel and open - RealTek HD Audio manager
On the top of Page are 3 Icons -
One Icon is labelled Speakers One is for Digital optics, one is for Mic,
The Speakers Icon is misleading as it is also for Headphones (LineOut)
Select Speaker Icon and make it Default. Also tick Full Range - Front LR
Ignore the 4 vertical Analog Icons on the right side.
You should now have Headphone sound if your volume is not Muted.
Hope this works for Y'all.
try right clicking the speaker icon and going to playback devices/ plug in headphones, write click the headphone icon go to test/ see if you here anything then set the headphones to default it worked for me.if that does not work try updating your audio driver/if that does not work try uninstalling your audio driver and installing a new one like realtec audio driver.
The application will not recognise the different output device until you restart the app. The different audio output device needs to be set as default (in Control panel Sounds) and then you need to restart the app. It should then automatically use the new default device.
I was also hoping that someone had written a utility to force this change, but I suspect it's application dependent.
ok, I did find that place where the little GUI LED senses the jack is plugged in or not, apparently my LED doesn't light up when I plug in the audio jack. I assume it's the hardware problem with that audio panel pass through board, updating drivers didn't seem to help, and opening the laptop up there was no loose connection anywhere, will find out when my new panel board arrives next week.
I followed those steps and it didn't work, but here's what did:
under Control Panel>System>Sound, Video & Game Controllers I uninstalled all devices listed, then restarted my laptop. Windows automatically found the speakers and reinstalled them. Then I plugged in the headphones & went back to Control Panel>Sound and set the headphones as the default device, then restarted again. Works perfectly now!
Did what you said and solved the problem. Somehow the balance on the headphone jack had been moved all the way to the left channel. Fixed the problem in seconds, THANK YOU, saved me lots of messing around.
