OK, my volume keys stopped working ,neither volume (in music app for example), nor switching between profiles.But the volume keys does switch profiles in case the status menu is opened (so its a software issue not hardware).in addition, the 'beep' sound of switching profiles is gone now.
I searched and posted in another thread but i got no solution , i hope some one could help me here
edit:
i noticed this after installing unrestricted-ui, Mt-toggles, and some toggles and editing some of them, dont know if its related
