Headphone setup on dual monitor

[morryplayground]

Hey guys, I'm new here.
I'm using a headphone while I play online games with a dual monitor. Problem is that when I plugin my headphone, it will only play the sound on my other monitor instead of the monitor which I'm playing games with. Any idea on how to setup this up? Thank you in advance.

(win 7) Right click volume control (bottom right of desktop) then click playback devices. Locate and highlight the monitor you want to use (if it supports it) then click set default device (not default communication device). This will select the monitor you want for audio playback.

First things first. Thanks for your prompt reply. Though it's still not fixed yet. My rig is newly setup and when it comes to audio, I'm a noob.
In the playback device, it shows that I have quite a few other devices which I have no idea what they are. 1)AMD HDMI output 2)Speakers (realtek high def audio 3)Realtek digital output (Realtek high def audio) 4)headset 5)Speakers (WsAudio_device1) 6)Speakers (WsAudio_device2) 7)Speakers (WsAudio_device3) 8)Speakers (WsAudio_device4) 9)Speakers (WsAudio_device1)
Is there something wrong with this? Before I move on to fixing my headphone problem, should I have this fixed first?
