As we know, Plex can support wide range of media formats.If your device supports it, Plex will stream it directly. If it doesn’t, Plex will transcode it to an acceptable format for your device. While, things are not so easy as we expect. When guys playing MKV via Plex, problems always around them:
Plex not detecting MKV files
“I have a diverse library of video files, many of them in mkv format. All other files play without problems but while transfer mkv files to Plex Media Server, it stops and go with buffering and reloading messages.”
In fact, MKV is just a container format, holding video, audio, image or subtitle files in it. The video and audio files in different MKV files can be encoded with different codecs. The Plex does not currently support Direct Playing all of MKV container videos. If the audio and video streams in the file are otherwise compatible, it will be Direct Streamed.
Play MKV files via Plex no sound
“I installed the Plex Home Theater on my Windows 7 PC. The PC is connected to the TV via HDMI, the audio output is connected to the audioreceiver via optical cable. I have a Plex server running on a separate PC. Everything was working fine untill I lost sound when playing MKV files. The MKV files I currently have shown up with no problem.”
That is to say, some of your MKV files with DTS audio, as Plex claim: DTS audio is not currently supported directly. Content with DTS audio will have the audio automatically transcoded to either AAC (default) or AC3 (if the Dolby Digital (AC3) receiver capability preference is enabled) by the Plex Media Server in order to preserve the surround sound audio channels.
