OKAY, now it looks like that we have found the/one reason for the stops. I turned off the phone two times, started radio and then PA and no problem, although Audiofocus is "on" in short and permanent.
From our conversation I haven´t got the impression, that this is an issue that have a lot of people, so I asked myself two questions
- what are you using and might be few people do?
- what are you using regularly?
Answer: the App from the best Spanish radio "Cadena 100"
So I deleted the app and made the same procedure: phone off, phone on, other radio channel, PA, no problem. I did it twice: no problem.
"Cadena 100" has it´s own app, but you can hear it also via other radio apps, that offer more channels at the same time. So I uploaded "Radio España" that offer also "Cadena 100".
I tested it now three times: no stops anymore.
Is there any logic behind this? Is it possible/known that some sites can cause this problems?
But we have to wait 2 days, there have been yet some surprises ...
