Sorry to hear about your troubles with the new system.  I will do anything I can to help you, ok.

Have you tried your advanced speaker and volume settings on the control panel sounds tab.  I heard that you have a 7.1 setup, you might not get sound out of all the speakers all the time, it may depend upon what you're listening to.  Also, check your sound card settings, if you have one, but I would think that you do.

You're mic input should be right by your other speaker inputs.

Hope this helps, and contact us if you see Gina or me online at all today,ok.
