Media player classic home cinema play all soundtrack together on movie,how can i fix?

[envagyok]

Hy !

I have the latest 1.1.0.0 media player classic home cinema, and i meet a strange problem:
Before today everything went fine, but today night i want to see a mkv movie with dual audio track. The mpc-hc plays all of audio track same time, and i cannot change the audio in the menu.

How can i fix it, when i want to hear just one audio stream at once?

Thanks for answers.

Re-enable the internal stream switcher.
