Please me help me make my 5.1 suround sound work

Please see the first post, I have that information in there towards the bottom.

EDIT: Was talking to a friend at work and it hot me that we may have a miscommunication here--I have sound--it's just stereo only and I want the full surround sound I know my hardware is capable of. There is sound coming out of my speakers, just not all of them when I test the playback using the speaker-test command (speaker-test -c 6) has only ever given me 2.1 sound at best.

I'm not so foolish to think everything can use all the speakers--it must be made for 5.1 sound, I know this--but I want there to be configuration options in the volume control which seem to be missing and I want to hear all the speakers working on films which have the full 5.1 soundtrack in them and in tests which are supposed to playback in all speakers one at a time.

I apologize if there wasn't any misunderstanding but it seemed to me the last few posts were assuming that I had no audio at all. I do have stereo, I just want the full 5.1 sound my card is capable of. Thank you again for the time and energy you're expending here trying to help me with this. I appreciate your patience troubleshooting this between my work hours and sleep.
