No audio with push alerts

No audio alert with push notifications

To get help, a little more information is useful. iOS, Android, Version,…

I used to get the audio Morse or blip alerts. Now still get the push notifications but no audio accompanying them.

Thank you for responding. As I said, it worked fine for 2 years then abruptly stopped. Still getting the push texts.

iOS iPhone 13 max

iOS 16.1.2 iPhone 13 Max

Still no audio alerts Get push notifications just no Morse audio.

I use Adroird 13, but no Morse or Beep sound possible

Can you give some more details, like is it a native Android?
Which phone is it?
I am not in the details of developing but such errors are really hard to debug.
