Public bug reported:
No audio comes out of the right speaker on the laptop. 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.
