Still, the issue with the right speakers persist. I am not proficient in
running or compiling scripts or programs in Linux. I am currently
running Ubuntu 19.04. The strange thing I noticed is that the power
switch toggle [even a soft toggle without fully turning on/off] fixes
the right speaker immediately. However, whenever there is loud audio,
the right speaker turns off (i don't know if its some channel or stream
that turns off).

  No sound from right audio channel

Bug description:
  No audio comes out of the right speaker on the laptop.  When playing a
  test video such as 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.
