Hi,
AC3 passthru on the cs4299 is not implemted right now, is anyone on the list willing to help. here are some info about the registers from cirrus ----------------- basically there is no longer support for codecs. but here is some info that might help. this is really all that i could find out. the doc is on the website, let me know if you can't find it. * power down playback SRC (because output is not bit-exact, even at 48 kHz) * power down (or mute) DAC (because AC-3 sounds bad when converted) * set /Audio bit (see page 31 of DS319PP5) thanks tom woller --------------------------- CU Bernd Zierath NHY隊X'u'$ح"wzyN\jkz+jw_bnWמv+h*.quڲ"Z0.fj+xTD}k$뉩p%v+\oy+%^fj)b b%^elqzm?X(~zwXb?j[u
