** Description changed:

- target machine does not have built-in speaker, and the monitor does not
- have an audio output (like d-sub VGA)
+ For linux kernel (oem-b):
+ 
+ [Impact]
+ On a Dell machine without internal spk and internal mic, after freshly
+ install the bionic on it, and users plug a headset, the sound couldn't
+ output from headset.
+ 
+ [Fix]
+ reverse the order of headset mic and headphone mic
+ 
+ [Test Case]
+ freshly install the bionic with this patch on that dell machine,
+ plug headset and play sound, we could hear the sound from headset.
+ 
+ [Regression Risk]
+ Low, this patch only affects the machine without internal mic and
+ internal spk, and I already tested this patch on the machine without
+ internal mic and internal spk, it worked well.
+ 
+ 
+ 
+ target machine does not have built-in speaker, and the monitor does not have 
an audio output (like d-sub VGA)
  
  As first boot, there will be a "dummy output" in g-c-c.
  
  After plug-in headset, there will be a headset appear in g-c-c, but it
  won't be automatically selected even it's chosen in the pop-up window.
