No Alarm Sound

[TatteredandTorn]

So I've had my galaxy S9 plus for almost 2 years, I ALWAYS have it on silent, but for 2 years I could set an alarm and it will sound off. Recently I broke the screen and got a replacement device (same phone), right after setting up my new device it updated to android 10, now if I have my phone on mute or vibrate the alarm doesn't sound. Is this an android 10 thing? If so, how can I revert back to android 9?

The same thing is happening to my S10+, even though I have never broken it.. I'm not sure if there's a legal way to revert to Android 9, though :/
