Notification.beep and media.play working only a certain number on Android

Hello,

i noticed that playing sound files and notification sound only working a certain number if it is played one after the other.

Then it stoped working an i have to kill the app and restart.
 

So i try the simplest example.

In Phonegap Desktop the Blank example with:

<a href="#" onclick="playBeep(); return false;">Play Beep</a>

<script type="text/javascript" charset="utf-8">   

     // Beep
     function playBeep()

{          navigator.notification.beep(1);          console.log("beep");      }

</script>

 

on Android 5.1.1 after 26 times stuck

on Android 7.1.1  and  8.1  after 14 times stuck

on iOS  I did not observe that

 

 

Now, i make a loop that beep every 2 sec.

 

I explore that Android 7.1.1 beeping again after every 5 minutes but only then 14 times

 

And i try lower versions of the cli.

but that doesn't make any difference whether cli-6.5.0 (6.1.2) oder lower 4.1.1, 3.6.4 etc.

 

 

And thats a huge problem.

Example - a chat that can only make "pling" 14 times in 5 minutes?

 

 

On android 7.1.1 and 8.1 is the intervall 5 minutes and beeping 14 times,

on android 5.1.1 the intervall is 3 minutes and beeping 26 times

and on android 4.4.2 it's beeping infinitive

 

So what if it's not a problem from phonegap / cordova but from android itself??

 

with Ionic the same - play 14 beeps only..
