Hi,
the reason for AC3 passthru is my little VDR box http://www.activy300.1xu.de/ , there
is a bitstream plugin
for VDR that can use the alsa driver like ac3play from alsa.
Right now I'm still looking at the code but can't fine the right place to send the
bits to the chip.

Another question: do you have to be able to access the IEC958 directly to
send AC3 to it? Currently the cs4299, cs4297a, and the cs4294 merely copy the
playback data to the IEC958 port, without direct access. Could you simply
power
down the playback SRC and the DAC, send data to the card, and let the codec
copy
the unmodified steram to the IEC958 output as usual, allowing an AC3 stream to
be
sent to an external decoder?
I realize there may be timing and other issues involved, I'm only asking
this
from a theoretical standpoint
