Public bug reported: I'm running Ubuntu 20.04 and have noticed that after logging back on to a machine either after its been asleep/suspended or logged out due to inactivity the sound is much louder at the same volume. I haven't enabled amplification or any other sound feature.
To duplicate, boot machine with volume at say 50% and listen to some music. Let it either log out or suspend/sleep and then log back in, start music/sound and it will be much louder. In fact this louder sound at the volume sounds correct, because the windows boot sounds the same at that level. When ubuntu boots the volume is much softer. The sound post logging in after a suspend or lock out is what it should be from the get go.
