Public bug reported:
alsa-driver was selected automatically. I don't know if that's the
problem. I'm newbie. I just want to understand when it will be triggered
(if it's a feature) so I can avoid increasing the volume to the max
accidentally.

Title:
I use the buttons on the keyboard to adjust sound (F1 mute, F2
decrease, F3 increase). More often than not, I push two to four times
until the sound gets to the level I want. Sometimes it gets automatic
after I press, and takes it all the way up, or all the way down. I'm
not sure if this is a feature or bug but I can't figure out when it
will be triggered, thus I end up pumping the music at very loud,
uncomfortable levels until I get back my control from panic and
decrease the volume to somewhere acceptable. There are times it
automatically goes to complete silent from there which is still
annoying although not as much as the first one. [81AX, Intel Kabylake
