Documented Problem: ”Hi, Sorry if this kind of thread exists already but here is my problem. I just bought an openjour chameleon. I put an external HD with MKV on it by USB. When I play the file, I can see the movie but no sound at all... The MKV files work fine on my computer and it used to play with sound in my previous media player (popcorn). Please I need some support to solve this issue thanks” 

Firstly, please make if you can’t hear sounds at all and is the OHC directly connected to the TV or is it via AVR? If directly to the TV I assume the TV can't decode DTS sound. Unlike the popcorn players there is no downmix on the native player so unless you have some audio device that can decode the audio you'll hear nothing on some audio types. You can install software that can decode the audio. SPMC is the most popular and has a myriad of other addons and abilities.

Why Convert DTS to AC3, MP3, WAV, AAC, etc? 

DTS (Digital Theater Systems) and Dolby Digital (AC-3) are the two most famous audio codec used in professional cinema and home theater system to record and play back multi-channel high-definition audio. We often see them at the end of a film when we watch it in cinema or play a DVD at home. Moreover, we often see DTS or AC3 audio in MKV files, because these files are ripped from DVDs and the audio are kept unchanged. 

DTS is adopted by DVD specification later than Dolby Digital AC-3, so some older DVD player or hi-fi system only support AC3. To play DTS in these systems, you need convert it into AC3 format. For other users who want to enjoy their splendid DTS musics in their portable devices like iPod, iPhone, iPad, Android, etc and popular players like Windows Media Player, QuickTime, PowerPoint, etc, converting DTS to AC3, MP3, WAV, AAC, and FLAC etc is a customarily and highly recommended way to play DTS files anywhere without limit.
