When playing a test video such as https://www.youtube.com/watch?v=hTvJoYnpeRQ the right-channel audio is never heard (i.e., it does not get converted into mono and played through the left speaker). When plugging in headphones, audio is heard from both channels. In Windows, both speakers work, so it is not a physical problem with the speakers.

Never used bug tracker before. Just want put more voice to this bug as I have a Matebook X as well. Only one of the speakers work. I am sure there are others buying this machine and wants to run linux variants.
