Try it in the back to rule out a problem with the front panel jack.
I can hear sound through both front and rear, the mic level doesn't move on either front or rear.
When I unmute the mic under speakers
Can hear myself on both front and back. When muted, no acknowledgment from the mic at all.
run the mic level all the way up. Problem solved?
Mute it again under Playback unless you want to hear yourself and any other sound in the room.
have you ruled out the mic itself as a problem? Try a different mic or a different computer?
