[Pkg-bluetooth-maintainers] Bug#846835: bluetooth: Sennheiser MM400-X headset delayed sound using pulseaudio

[Adrian Immanuel Kiess]

Package: bluetooth
Version: 5.43-1
Severity: normal

Dear Maintainer,

   * What led up to the situation?
     Playing audio on my Sennheiser MM400-X bluetooth headset
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     Pair connection with Gnome Bluetooth or Blueman and play audio with
mplayer or rhythmbox
   * What was the outcome of this action?
     Working sound, but after some hours active bluetooth connection the sound
has up to three seconds delay
   * What outcome did you expect instead?
     No audio delay in playback

in Debian/testing my Senndheiser MM400-X bluetooth headset works fine, but
after certain time of an active connection the audio played back via pulseaudio
has an up to three second delay.

Additionaly the connection gets lost maybe all three to six hours active
connection.

I hope it is possible to fine tune the Linux bluetooth stack against my used
configuration.

Thank you very much in advance.

With many greetings,
