re a problem with unpluging and pluging in the headphones

[reble]

I have a Gateway model MD2614U laptop os Win7 home 32bit. When I unplug the headphones to use the internal speakers sometimes the laptop will switch over and sometimes it won't. When it won't switch over. I open the volumes control window and I can see the green bar going up and down with the audio source but there is no sound coming out. I have to end up closing down the program that is producing the sound then the switch over will complete and I restart the program. I also have the same problem when I plug the headphones back in, again no sound from the headphones even though I see the green bar moving. Also some programs that send and receive audio over the internet will lock up when I unplug or plug in ether the headphones and or the microphone. Does anyone have any ideas on this problem?

right click the speaker icon on the taskbar and select playback devices,
when you see the headphones with the green bar, try setting them as default .
(click on them to highlight them and then click set default then click apply then OK)

hopefully when you unplug them your sound will revert back.
