It is an audio code (CODEC) issue. Since we can't change the decoding in the TV we have to re-encode content to what works. And here's the hard part. From model to model, said encoding may work on one but not the next. This makes it impossible for anyone to nail down exactly which encoding to use.
Now a little correction is needed. MKV is not a format, it's a container for content. As such MKV is fully supported but what you toss into said container may not be supported.
Sorry if this is confusing but it is at first.
I am able to play few mkv files but others i am unable to. I dont know if it's the audio codec issue. If it is, then what is the solution?
