I also found what cause this odd problem (yes, its verified that the AC3filter is used right now!):
...when i select into this checkbox anything else that System default, the ACfilter simply disapear from the Options/Filters menu (also from the advanced section there!) when playing any AC3 movie. Build 807 and 808 affected, not tested others yet :oops:
Quick fix - select System default :roll: ...and everything working again fine.
...a bug :?:
AC3filter 1.01a used, BSplay 1.0 build 807/808 used on Win2kSP3 machine with SB AUdigy2zs and 5.1 speakers. Also tested on WinXP SP1a machine with crappy onboard 2channels audio s*it :roll: :?
