** Description changed:

  When trying the 2.6.35~lucid1 backport kernel in 10.04, the Audio device
  doesn't auto powerdown after a reboot.
  
  powertop reports:
  
  An audio device is active 100.0% of the time:
  hwC0D0 Realtek ALC272X
  
  Once I mute/unmute the audio, the device will drop into power-savings
  mode when unused, and powertop report 'device is active 0% of the time'
  when it isn't in use, and will stay this way until the next reboot.
  
  Using the default kernel (2.6.32-24), the device properly enters power-
  savings mode after a reboot:
  
  Recent audio activity statistics
  Active  Device name
    0.0%  hwC0D0 Realtek ALC272
