Can't Play TrueHD thru Sony BDP570

Can't figure out how to get my BDP 570 to play TrueHD. I have created an MKV file that according to MediaInfo contains a 1920 x 1080 AVC video stream and a 6 channel TrueHD audio stream. This file was created using HandBrake and MKVMerge. In it's current configuration, the MKV file refuses to appear on the Sony menu even though the Show Status button shows Serviio has found the file after a Force Refresh. What is my next step?

Thanks to all.

Could you provide information about your mkv file (ffmpeg -i) ? see my signature links.

Thanks for your help

I don't know how similar the BDP570 is to my SMP-N200, but mine do stream TrueHD from my MKV or M2TS files.
