How about putting your ego back in it's box and actually trying to spend time carefully doing all the things I suggested.
Documentation for Pro Tools products is usually included in the install. I don't know about Express. As a start look under the Digidesign or Avid folder under/Applications.
Here is your most basic install/setup
http://akmedia.digidesign.com/suppor...uide_80354.pdf What would be good to hear is you followed those exact instructions.
All the main documentation for Pro Tools v10 family is here
http://avid.force.com/pkb/articles/e...guide/en419211. You should include the (imposing looking) Pro Tools 10 reference Guide. That is the only place to get lots of detailed information, especially once you have basic stuff working. Express is basically just a crippled version of standard Pro Tools 10. And without an Express specific gettign started guide the Pro Tools 10 Reference Guide is your place to be.
YouTube -- lots of likely useful videos.

Here is a curated beginners list...

Again we cannot guess what you are trying to do. Are you trying to hear prerecorded audio in a session? Do you even have any audio in the session at all? Are you trying to track a microphone? keyboard? guitar? To an audio track? Or are you confused and trying to use an Instrument track for audio? How the hell can we guess? I suggested *exactly* what you should try if you don't have a tutorial/demo session. Did you try that?
And again.... and provide info on your system etc. as asked for under the "Help us Help You - READ THIS Before Posting!" link above on this and every other DUC Web page.
And example info would include what exact make/model headphone (Skull Candy is a brand, what exact make/model?), a description of what audio content you are trying to hear, what all the Solo knobs are set to, whether waveforms show up in the Pro Tools edit windows or whether the Pro Tools meters move, etc. when you press play. We cannot just guess what the hell it is you have and are trying to do....
Post screenshots of the edit window showing the tracks you are trying to play. Make sure that screen shot clearly shows the IO input and output sectors on the tracks (if you don't understand that ask).
