I Attached a picture. I need to use AC3 filter and Cyberlink at the same time but they should be connected somehow like i draw in red. The Problem is that if i connect them like in "not on option!" then there will be no 5.1 audio. Cyberlink only filters stereo trough and then ac3 filter will not filter it back to 5.1. But if i use like i draw in red. Cyberlink gives stereo bass, ac3 gives 5.1. I hope u understand my logic. Or is there another magic program to do something like this? I know my post has some resemblense with my other previous posts. but Im just still stuck with my same old problem. I cant get 5.1 sound with cyberlink audio decoder, but i need to use it bc of the bass. So I think this is one solution to my problem in above, but cant get it working :(
