After the latest update, system sounds and notification sounds disappeared S21

[Qwezy]

Suddenly I discovered that system sounds and notification sounds disappeared after the last update. There is no sound of pressing dialing keys or screen lock clicks. There are absolutely no notification sounds. At the same time, notification sounds are not played in the settings when they are selected. Don’t even try to write to me about the volume level, modes without sounds, etc. What was done:

1. Reset to factory settings - the problem is not resolved.
2. Installing the latest firmware for my phone and region via Odin to the latest version - the problem is not resolved.
3. Installing firmware for a phone for a different region - the problem is not resolved.
4. In safe mode, there are no notification sounds or system sounds.
5. Removing unnecessary programs and services via ADB - the problem has not been resolved.

I also want to note that after each reset to factory settings, everything works for 30 seconds, and the notification sounds that come are the system sounds. Soon they disappear. Before this, there were no problems before the updates. It happened suddenly.
I also want to note that, for example, in WhatsApp in the settings I can select sounds and hear them, they are not played in the phone settings. Third-party sounds are also not played if you download and add them.

The sound of the call, music, video works, checking via *#00*# showed that all speakers are working. The problem is in the software, and Samsung doesn’t want to solve it.

Oh, and I don’t have a watch, Bluetooth headphones or anything else. I repeat, before the updates, EVERYTHING WORKED NORMALLY!

Have you enabled this setting:

I tried turning this option on and off. Turning it on or off does not solve the problem unfortunately. I also want to note that there are no system sounds and not just notifications. The sounds work for about 20 seconds after rebooting, then disappear.

Sure, but for each app you want notifications for you need to enable them specifically. If you haven't already, go to notification settings, choose the app that isn't sending notifications, then notification categories to check what you need enabled

No matter how I configure it, it won’t help. You understand that when I select the notification sound in the settings, they do not play, there is silence. Therefore, until the notification sounds start playing in the settings, I think the problem will not be solved no matter what I choose. At the same time, ringtones play without problems. And what you are showing, I have already done, it does not help. The problem is hidden deeper than it seems.

Could you post a screenshot of which settings option you are using that doesn't play the notification sounds ?

How about these settings:

In the list of notification ringtones, if you press silence on them, they do not play.

So in that 1st screenshot, none of the notification sounds play anything if you select them, there's no sound preview?
