This article gives you the solid way to stream MKV files with AC3 5.1 or DTS audio to Roku via Plex beautifully without any hassle.
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.
