Package: bluetooth
Version: 5.23-2
Followup-For: Bug #721036

Dear Maintainer,

maybe I have a similar problem.

   * What led up to the situation?
I switched on bluetooth mode both at my radio and my laptop.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I successfully connected both, changed audio output to the radio and also
succeeded with this (the sound from the radio speakers was perfect).

   * What was the outcome of this action?
But then after some time playback stops.

   * What outcome did you expect instead?
Playback to continue.


Maybe this helps:
