"Is there a way to play .mkv files on my Acer Chromebook? The file plays without audio."
Chromebooks fit the bill for their simplicity: you don't have to be a system administrator; you don't need to worry about backups, security, software updates, or file portability. However, on the media side, Chromebooks are still struggling more than Mac, Windows or Linux computers when it comes to flawlessly playing every video file especially MKV files you throw at them. Sometimes, the MKV video plays but there is no sound just like someone mentioned above, or the video playback is patchy and shows artefacts that don't appear in video player apps on other computers. Sometimes, subtitles that should be there don't get displayed or the video doesn't play at all.
Why Chroombooks won't play MKV files well
I think Chromebooks (regardless of the manufacturer) don't support certain audio codecs as they're proprietary and Chrome/Google would have to pay license fees to the owners. MKV containers are supported but if the audio within the container is encoded in a proprietary codec, it won't play.
Simple way to get MKV files and Chromebook to play nicely
Other than hosting your video files on e.g. something like Google Drive and trying to play them from there, you could convert them to another container format like MP4 (where the audio gets converted into a different audio codec that Chromebooks play back) with an app like EaseFab Video Converter. It's a simple yet effecient way to solve MKV and Chromebook incompatible issues.
