I'm using AC3Filter v1.09a which came with CCCP. (my only codec-pack installed)

I can't get the sound to be distributed to my Logitech Z-5500 speakers, when playing back ac3 .mkv or .avi files through Media Player Classic HT

I'm using analogue connection to the logitech, no spdif, and I have setup my windows speakers settings in control panel as "5.1 surround speakers"

here are my AC3 Filter settings:

I'm getting only L/R when playing.

any ideas?

Realtek driver info:

Realtek Audio Driver 5.10.0.5636
Audio Controller: HD Audio
Audio Codec: ALC883/ALC662

thank-you
