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).

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.
