MKV no audio when streaming to Roku via Plex- Solution

The audio from my MKV files doesn't play when I'm streaming to my Roku via Plex. Looking around for any decent tutorials via Google, I found many guys have issues when streaming MKV to Roku via Plex. After further searching, I’ve worked out the solution to get the issue resolved.

MKV is the norm for high definition video content. Usually, these files have a 5.1 surround sound audio track. There are two issues with these 5.1 audio MKV files. The main issue lies with Dolby Digital(AC3) and DTS audio. These files only work over USB and the audio is only supported via pass through. This means Roku won’t help you out if your system doesn’t support 5.1 DTS audio.

If you’re a big fan of using Plex’ Direct Play, there’s a second issue. Plex has issues playing any MKV with 5.1 surround sound. If your media server is beefy enough, Plex will transcode the media instead, or the transcoding would take forever.

To keep the conversion time to a minimum, you need help from third-party software like Brorsoft Video Converter.This video app is professional on fast encoding MKV to Roku 4/3/2 friendly MP4 AAC format without any quality loss. In addition to converting MKV to Roku formats, it can also convert among more than one hundred videos formats including VOB, MXF, MTS, MVI, FLV, MOV, WMV, MPG, AVI, Yify videos to Roku supported video. What's more, this program comes with a built-in video editor that allows you to edit your movie files by trimming, cropping, adjusting video effects, etc.

If you are using a Mac, you can go to Video Converter for Mac. Now download this tool and follow the instructions to convert MKV with 5.1 sound to Roku 3/Roku 2 for playback.

Converting MKV to Roku friendly Video/Audio format

1. Run the MKV to Roku converter program and click add button to import the MKV files.

2. Click Format bar and choose MKV as output format.H.264 High Profile Video(*.mp4) from "Common Video" can also be recognized by Roku 4, Roku 3, Roku 2 perfectly.

Tip- Advanced settings: If you were having a problem with 5.1 surround sound in general (because your hardware can’t handle it, or because you want to use Plex’ Direct Play), click Settings icon and set the audio codec as AAC.

3. Hit the "Convert" button to start the MKV to Roku conversion.

After the conversion, you can hit "Open" button to quick locate the converted videos; now you can stream MKV to Roku via Plex without hassle.
