I am using Audigy 4 with kx driver
I connect my ps2/xbox to sound card spidf-in.
when I set the ps2 output as dolby digital 5.1
the problem come out
when ac-3 decode ticked in the mixer. no sound

when ac-d decode un-ticked in the mixer. only have noise

I am using media player classis to listen to the sound.
and ac3filter is active. but it told me the input signal is only steroer PCM

what can I do? Please~~ HELP~~~

I posted a bug a while ago regarding AC3 decoding... seems if its sent stereo content - channels are not right...

by the way... kX AC3 and AC3 filter are completely unrelated as far as I know.
And Im not sure how you are listening to an external SPDIF with media player classic...

Bottom line... kX SPDIF AC3 decode (for me, on my live drives SPDIF input) is buggy. I *can* make it work for a DVD, but strangely enough I have to set my set top DVD player to output DTS. And yes it does work... And I dont need to run anything other than kX mixer to hear it.
but you may notice sync issues (audio / Video) Not all surround encoding is created equal it seems.
