Sorry, but you guessed wrongly. The new kernel comes with a new alsa-driver
(1.0.18a).

Every time alsa-driver changes my volumes also go down. This has nothing to
do with pulseaudio.

People need to understand that alsa is very complicate.  It needs to deal
with hundreds of different hardwares. Sometimes, they change some defaults
and break something for someone.

C'est la vie. With or without pulseaudio, alsa continues to be complicated
and having a lot
of problems. If you are lucky to be in the set of users well supported,
good. Otherwise,
the road to the fixes is very long ...
