Windows 7 - no sound

My OS is win 7 prof 64 bit and my PC is a lennovo M72e.  My speakers are a gateway DTSS-2400 Theater Sound System (FPD 2485 W compatible) speakers which is connected to the Monitor.  The sound was working fine, until I connected my earphone (Mron earmate) to the front ports of the PC.  I can hear the sound thru these headphones, but when I unplug the wires, and I play a sound, I do not hear the sound from my gateway speakers.
I have checked the Device manager and there are no exclamation marks on the sound or anything.  
Hope the Gurus can please trouble shoot for me on what to do.  Thank u.

under playback devices (right-click sounds), ensure the default is the correct port.  you can right click each and run a test until you find the right one and then right click it and mark it as the default device.
Did you check the Playback devices tab to see where the sound is and the default device?

go to control panel, sound and see if there is a check to use monitor speakers

In response to Fredbear891, Yes, there is a check mark on the Speakers, and the others are listed but it says "not plugged in".   When i test the speakers using the headphone, I can hear the sound, both from the left and right.  But when i unplug the headphone, and try the gest the gateway speakers have no sound.
- Single Left-CLick your 'speaker' icon in your taskbar and select 'Mixer' from the bottom.
- Under the 'Device' section, there should be a drop down menu directly beneath the word 'Device'.
- Select the drop down menu and  verify the volume level is not set to mute for both the 'Speakers' and the 'Headphones' options. If muted, raise the volume and retry.
In response to Machienet, There is no Mute on the screen, all the levels are set to the top most loudness.  Both the Device and the Applications are also on high. And there is still no sound coming out of the Gateway speakers. Thank u for your suggestions.
Have you tested the speakers on another machine?

One thing that rarely happens but could be a legitimate problem is your drivers just might not be up to snuff for dealing with switching outputs.  Check with the device manufacturer's website and see if any new drivers are available for your computer's sound card, and maybe your monitor as well.
Excellent and correct solution, thank u.
