Yes. The names "AuxN" are used for the cs4235 but not for the cs4236. 
The cs4236 have been using recommended line sources names (CD and Line in)
instead. I changed these names to be the same for the cs4235.

I can revert that. The "Master DAC" is drawn in the docs as a mixer after 
the DAC (on the DAC analog output). For me the DAC is more intutitive
but I can revert that.

The beep bypass switch connects directly the beep input (aka mono input) 
with the mono output (if it is used at all). The beep signal is not affected
by the "beep playback switch" and "beep playback volume" controls then
(it bypass the analog mixer). It is a routing switch.
