 here. Note that the controls work as attenuators: the maximum value is the 
 neutral position leaving the signal unchanged. Note that if the  same destination 
 is mentioned in multiple controls, the signal is accumulated and can be wrapped

     S/PDIF should output the same signal as channel 3+4. [untested!]
 
 
-Digitial output selectors
+Digital output selectors
     These switches allow a direct digital routing from the ADCs to the DACs.
     Each switch determines where the digital input data to one of the DACs comes from.
     They are not supported by the ESI windows driver.

 ALSA uses kcontrols to export audio controls(switch, volume, Mux, ...)
 to user space. This means userspace applications like pulseaudio can
 switch off headphones and switch on speakers when no headphones are
-pluged in.

 The old ALSA jack code only created input devices for each registered
 jack. These jack input devices are not readable by userspace devices
