No Audio With Matroska Video File

Hello,
I am trying to get a video file identified as an avi file to play.I have a Roku 2 and am using the profile for Windows8/RT to enable .flv files to play with audio....it works great! When trying to play the Matroska .avi file , the video plays fine , but no audio.I have tried all the profiles furnished with serviio v.1.42 and none will play the audio. In MediaInfo ,the info says the video is AVC and the audio is 48khz 16bits 6channels AC-3. Can I modify the Windows8/RT profile to play this type of file? If so, could someone supply me with the exact information to modify it...where to put it , what to change, etc? Thank you

??
A matroska .avi file ?? avi is a container format (usually embedded div-x video codec), matroska is a container too (usually embedded AVC/h264 video codec)

Could you provide MediaInfo result (and ffmpeg -i result, see signature links) ?

Thanks for the quick reply. Here is the info you requested:

Ok, so your file has a bad extension. It should be *.mkv

This is a MKV container with AVC/h264 video and AC-3 multichannel audio and it seems good.
With Windows8/RT profile, this file should be transcoded into mpegts/AVC/AC3 stream.


EDIT: There were some test with Roku devices here : viewtopic.php?f=5&t=15402&hilit=roku&start=60#p89696
