I think it will work; except I think there is more than one cap on both input
and
output sides that you need to deal with. I believe that one of our engineers
had to
do a similar thing last year for a customer. Please let me know if it works for
you.

Hi Everybody! i have a trouble: i am trying to use the audio codec of
the board, but it has an analog stage before the codec (50ad) that
eliminates DC (i see on the schematic "5402_DSK_schem.pdf"). If i
need this DC, it would work if i short-circuit the capacitors.
This also is present in the other sense (output). if i want to send
out a signal with DC component, may i short-circuit the caps too?

Thanks a lot
