Public bug reported:
I am on a Lenovo Ideapad 330. I've switched to Ubuntu from Windows. The audio
quality in Ubuntu is horrible to say the least, It is very low, and in case I
use VLC or enable overamplification, the quality of sound output becomes worse.
I have ensured that the volume on alsamixer is 100.
