Ubuntu – Can I hear only a few audio channels when playing video files


When I play specific MKV files there is not all the sound. There is actually only the background sound, like a song on the background, but I hear no talking.

The strangest thing is that it is not for all MKV files but for some. I can however not see a difference between the different files.

This is happenning because you have stereo speakers but that MKV has more than 2 audio channels and the "talking channel" isn't being down muxed to stereo. Go to System Setting/Sound and try to find any configuration related to output mode and change it to Stereo Speakers.
