Realtek driver problems with Windows 10

Hey before i mention my problem i explain my situation:
2 user accounts on a windows 10 machine on user1 sound works fine and just from time to time the setting for spotify gets reset on boot (its set to 30% and jumps to 100% from time to time.)

on user2 on the other hand it resets permanently - its also set to 30% but everytime you reopen any programm (chrome,spotify etc) it jumps instantly to max again

i dont think services or settings can be the cause as i copied the settings from account 1 (so all services that were enabled/disabled there are also disabled/enabled on this account)
but now a friend told me realtek is a cause of this but im not so sure about that as both accounts use the same driver and on account 1 it doesnt happen that much (for chrome not all for example)
to be fair i updated drivers 3days ago and have only been using account 2 since then (since then it happens instantly) but it happened even before that on both accounts so how likely is it that realtek is really the cause?

edit: systemsounds for example just jump back to max volume instantly,every time aswell.
id be happy about any suggestions.

things ive tried:
update drivers over device manager
every setting in audio (turn off that sound adjusts when you get a call,turn off every enhancements etc) but nothing helped.

UPDATE: ive logged over to my original account just to test some stuff,ALL settings are the same for audio,realtek has the same driver and the same services are running
result---> spotify still goes to max volume on restart even on that account,but chrome does not. - if i set chrome to 30% on that account it stays there even after closing and opening chrome or restarting so i assume there has to be something wrong with the second windows account i created? or im missing some setting?
any advice?
