[Bug 1519809] Re: No sound is routed to bluetooth headset after a call


There are two connections for HFP. One is the service level connection
which is used for exchanging AT commands which is setup all the device
the device is connected on HFP even if no call is active. This way we
also accept/decline calls. The second connection is the actual SCO
channel fo sending the audio data which is opened as soon as the
headset_head_unit profile for the PA bluetooth audio card is set.

  No sound is routed to bluetooth headset after a call

Status in bluez package in Ubuntu:
  In Progress

Bug description:
  After the latest update to bluez5 no sound is routed to the connected
  bluetooth headset after a call is ended.

  Steps to reproduce:

  1) connect a bluetooth headset
  2) Receive a call
  3) End the call
  4) Try to play music

  Expected behavior:
  Music is routed to the connected headset

  Current behavior:
  No sound is routed, although music player behaves as it was playing normally.

  Additional info.
  If you receive a second call, the audio is again routed normally to the headset after it's finished.
  Just tried with old images with bluez4 and it works as expected.
