Hello, my Mac isn't sleeping when idle.


I went in Terminal and typed in: pmset -g assertions (got that from )


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: "'AppleUSBAudioEngine:Unknown Manufacturer:Microsoft LifeChat LX-3000 :3a100000:2,1'.noidlesleep"

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



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)
