JS0INT  
This bit indicates that Pin JS0 has generated an interrupt. This bit remains set until the software services the JS0 interrupt, that is, JS0 ISR should clear this bit by writing a 0 to it. The interrupt to the system is an OR combination of this bit and JS1INT. The actual interrupt implementation is selected by the INTS bit (Register 0x76). It is also possible to generate a software system interrupt by writing a 1 to this bit.  

Js1 Interrupt 
This bit indicates that Pin JS1 has generated an interrupt. This bit remains set until the software services the JS1 interrupt, that is, JS1 ISR should clear this bit by writing a 0 to it. See the JS0INT description for details.  

JS0 State 
This bit always reports the logic state of the JS0 pin.  

JS1 State 
This bit always reports the logic state of the JS1 pin.  

JS0 Mode 
This bit selects the operation mode for the JS0 pin. 0 = Jack sense mode (default). 1 = Interrupt mode.  

JS1 Mode 
This bit selects the operation mode for the JS1 pin. 0 = Jack sense mode (default). 1 = Interrupt mode.  

JS0 Timer Enable
If this bit is set to 1, JS0 must be high for >278 ms to be recognized.  

JS1 Timer Enable
If this bit is set to 1, JS1 must be high for >278 ms to be recognized.  


 JS0 EQ Bypass Enable 
This bit enables JS0 to control the EQ bypass. When this bit is set to 1, JS0 = 1 causes the EQ to be bypassed. 
 
JS1 EQ Bypass Enable 
This bit enables JS1 to control the EQ bypass. When this bit is set to 1, JS1 = 1 causes the EQ to be bypassed.

Title:
  headphone jack sense not enabled

Bug description:
  bug is present in Ubuntu 12.04 and Xubuntu 12.04 and Lubuntu 12.04.1 64bit 
  alsa-base 1.0.25+dfsg-0ubuntu1 on this machine (64 bit)
  I except Ubuntu to automatically sense the presence of headphones and disable the speakers.  This is not the case, the speakers and headphones play simultaneously.  I must install gnome-alsamixer to manually set the jack sense.  Alsa should have this enabled as the default setting.  This seems as though it should be a very easy bug to fix, though.
