Absolutely no sound from my Android

[AC Question]

My android's speaker does not work at all, except with earphones, which are dangerous to use while, say, driving. I can't hear anything; no ringtones, no notifications, no music, nothing. I've tried everything, but nothing has worked. Can someone help me, please? Thank you.

Have you tried going to accessibility and check the "turn off all sounds" option? It should be unticked.
