Mac not sleeping when idle?

Hello, my Mac isn't sleeping when idle.

I went in Terminal and typed in: pmset -g assertions (got that from http://www.adeepbite.com/lion-seems-having-insomnia-it-doesnt-sleep-easily/ )

This is my result:

1/1/13 6:26:57 PM CST

Assertion status system-wide:

PreventUserIdleDisplaySleep 0

PreventSystemSleep 0

PreventUserIdleSystemSleep 1

ExternalMedia 0

UserIsActive 0

ApplePushServiceTask 0

BackgroundTask 1

Listed by owning process:

pid 166(coreaudiod): [0x00000001000003c3] 00:44:55 NoIdleSleepAssertion named: "com.apple.audio.'AppleUSBAudioEngine:Unknown Manufacturer:Microsoft LifeChat LX-3000 :3a100000:2,1'.noidlesleep"

pid 569(helpd): [0x0000000c000003cd] 00:20:55 BackgroundTask named: "com.apple.helpd.sdmbuilding"

It seems that my Headset: Microsoft LifeChat LX-3000, is causing my computer to stay awake.

How can I get it to sleep without unplugging it from my computer?

OS X Mountain Lion (10.8.2)

You can't have it sleep at idlle with assertions enabled. Your options here are to either use another headphone device or unplug it when you leave your system. Did you install any driver software for your headset?

Regardless of the driver being used, you have a device that invokes a power assertion that will keep your system awake as long as it is plugged into the system and is recognized. Unless Microsoft has a driver available that handles it differently then you only have these options available to you.
