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.

This is being moved upstream from the Ubuntu bug at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1721987
