Notifications sometimes make noise even though I don't have media volume synced with ringtones
There's 3 options for volume syncing:
Turn off volume syncing
Ringtone & notification
Ringtone, notification, and media
I have it on ringtone & notification which is on vibrate. However if my media volume is up, it still plays a notification sound.
Sometimes it works as expected and doesn't play the sound.
I have a video of me switching the volume syncing options without the new option being selected.
