What the.................

Jocking... Well I've tried ac3 filter, but I've the same problem I had using Power Dvd or Win Dvd... No sound with passtrought enabled or only stereo (the front channels) when spdif connected and internal ac3 decoding enabled.....
It' s a bug of kx drivers not a software problem because I've tried installing creative drivers, and all properly worked.
Hope eugene can fix it......
