I don't know if this is the issue you are having, but we've confirmed an issue in 7.2 where selecting an audio track via the Closed caption/audio configuration dialog does not work for some MKV files.

Re: help change audio does not work

I don't believe we have a solution at this time, there will likely be solution to the .MKV issue in a future firmware release, but if you are using HLS, that is a separate issue which I have a bug filed for, if you are using .mp4, files i'm not aware of an issue affecting those.

Re: help change audio does not work

There is probably a bit of a misunderstanding here, MKV is not a video format per say, its a container and allows multiple video and audio formats (the idea is to have one file which includes audio, video, subtitles, menus...). In another words, you can play one MKV just fine, but the other might fail simply because specific audio or video codecs is not supported https://en.wikipedia.org/wiki/Matroska

that said, I can confirm I cannot hear audio if the audio codecs is DTS format (my TV cannot decode it), I can hear the audio if it is AAC codecs

"If you are playing audio that is Dolby Digital or DTS 5.1 Surround Sound, make sure your audio subsystem or TV can decode Dolby Digital or DTS."
