Recently, probably after new update do MIUI 12 on my Redmi Note 7, I have this issue that my alarm sound doesn't work sometimes. Few days ago I didn't wake up on time and today I woke 40 minutes after scheduled alarm and looked on my phone, where was playing alarm animation, but no sound at all. I have also noticed that when I click turn off sounds button it is fine, but when I turn the sound again on it gets stuck for like 2-3 seconds, then the animation clicks and finally the sound of notification, on MIUI 11 It went smoothly every time. Does anyone has any advices about alarm problem, because It is really annoying?
