PulseAudio and ALSA volumes are unsynchronised after changing volume in guest session

I was listening to music while using my pc as a normal user

then opened a guest session and changed the volume level, after then

when i turned back to my normal account, the volume shown on the previous level, but the real sound level was just like the guest one.. i had to change the volume to get the real value on it
