I upgraded from 18 to Ubuntu 20.04 a few days ago. I listen to music through Google Play Music's website which I load in Firefox. I noticed that now Ubuntu has app specific volumes (cool). Since I stream shows and movies through Firefox I decided to crank the Firefox volume to the max and then fine-tune the volume on the website and with the system's master volume. The problem is that the sound for Firefox keeps resetting. In fact, it seems to reset with every Google Play song. I go from being able to hear my music to hearing silence. Why does this happen and can it be stopped?
For the moment, I'm leaving the Firefox volume to where it defaults and increasing the volume on the website.
