Problem with coreavc 2.5 and ac3 filter

[cvrak]

I'm using bsplayer and coreavc decoder for more than 2 years and suddenly I faced noise distortion in 1080p mkv files. This distortion occured sometimes, and I couldn't find a solution. Some days ago i changed some setting in ac3 interface , but the problem remained.

Yesterday when I tried to play a 720p 5.1 mkv file, I couldn't hear the sound. I had to go to audio/audio streams and there were AAC 2.0 & DD5.1 options. I choosed DD5.1 and the sound was ok. But in the Options/filters/AC3 filter the input was 2 channel, eventhough the mkv has 5.1 audio.
I uninstalled and re-installed bs player but the problem remained.
I uninstalled bs player, coreavc pro, ac3 filter and re-installed everything more than 5 times. The problem remains and now in Options/filters there is no AC3 filter, eventhough the ac3 filter is installed.

What did i do wrong?
What installation procedure do I have to follow in order to use bs player, coreAVC and AC3 filter?

Pls advise

After a lot of uninstalling and re-installing of BS player, AC3 filter and Core avc, I can't find solution about the sound problem.
I explain: the mkv file has 2 audio sterams, AAC 2.0 and DD 5.1
I choose DD 5.1, but when I go to Options/filters/AC3 filter the input is always 2.0 and its not possible to change it.
How can i make BS player to play DD 5.1 stream aytomatically?

Pls advise

Its a pretty big file, a 720p episode of Greys Anatomy, about 1,5 GB.
Is it possible to extract 1-2 minutes only?
The strange thing is that a couple weeks ago I hadn't this problem
