[Bug 1389781] Re: A2DP works randomly


After some more researches I found a way to make A2DP work, to do that I
need to put in /etc/bluetooth/audio.conf in [General] the line


(then sudo service bluetooth restart).

A2DP seems to work now, but there is an other problem which appears : I
can't use HSP/HFP mode which is usefull to record a sound from the

So is there a solution to make both HSP and A2DP usable without a need
to edit /etc/bluetooth/audio.conf and restart bluetooth ?

Thank you.

  A2DP works randomly

Status in “bluez” package in Ubuntu:

Bug description:

  There is a problem with the bluetooth mode A2DP. When I connect my
  bluetooth headphone, sometimes I can activate the A2DP mode (which
  gives a good sound quality) and sometimes I can't (nothing happened
  when I change it in the configuration window), and I need to switch to
  HFS/HFP (bad sound quality). Note that some logs are attached.

  I found on the internet a work around which is to put in /etc/bluetooth/audio.conf a line

  It seems to work (well it's hard to say for the moment because I
  didn't have the time to do much tests), but I would like to know what
  Socket is supposed to do.

  Would it be possible to solve this bug when Socket is activated too ?

  Thank you,
