Selection of language track playing MKV file

Hello,

I have brand new Philips 47pfl6907k/12
I am using DLNA playing 3D .MKV file. The file has following structure:

mkvmerge -i Filename.mkv
File Filename: container: Matroska
Stopa s ID 0: video (V_MPEG4/ISO/AVC)
Stopa s ID 1: audio (A_AC3)
Stopa s ID 2: audio (A_AC3)

ID1 audio is Czech, ID2 Audio is English

I can play the file, but when I am trying Options, I do not see any prompt for language selection. I do not know, how to switch between audio tracks.

In general settings primary language is Czech, secondary English...

Can you help me?

Best regards

There is no way to change the language. Already asked several time Philips for that, but it seems they are not able to fix that.
