Hello, All!
I am posting this because things have changed a little for the LL Citrine (3.x) series and other Ubuntu 16.04-based distributions.
Ubuntu and its derivatives now include a version of blueman that works properly in the repositories. As a result, the blueman PPA is no longer needed - unless, that is, you LIKE "living on the edge". However, what the Ubuntu 'gods' DIDN'T bother to do is include the necessary .conf files in the /etc/bluetooth folder to enable full Bluetooth support. In addition to the audio.conf file, a number of other Bluetooth .conf files were also excluded.
What follows is a copy of a working audio.conf file that can be pasted into Leafpad and saved to the /etc/bluetooth folder. That, and a reboot, will enable Bluetooth audio support.
First, we open Leafpad (or other text editor of your choice) as root:
Open a terminal window with CTRL-ALT-T, and type or cut/paste the following line:
sudo leafpad /etc/bluetooth/audio.confOnce Leafpad opens, copy [CTRL-C] and paste [CTRL-V] the following:
# begin copy/paste
# Configuration file for the audio service
# This section contains options which are not specific to any
# particular interface
[General]
Enable = Source,Sink,Headset,Gateway,Control,Media
Disable = Socket
# Switch to master role for incoming connections (defaults to true)
#Master=true
# If we want to disable support for specific services
# Defaults to supporting all implemented services
#Disable=Gateway,Source,Socket
# SCO routing. Either PCM or HCI (in which case audio is routed to/from ALSA)
# Defaults to HCI
#SCORouting=PCM
# Automatically connect both A2DP and HFP/HSP profiles for incoming
# connections. Some headsets that support both profiles will only connect the
# other one automatically so the default setting of true is usually a good
# idea.
#AutoConnect=false
# Headset interface specific options (i.e. options which affect how the audio
# service interacts with remote headset devices)
[Headset]
# Set to true to support HFP, false means only HSP is supported
# Defaults to true
HFP=false
# Maximum number of connected HSP/HFP devices per adapter. Defaults to 1
MaxConnected=1
# Set to true to enable use of fast connectable mode (faster page scanning)
# for HFP when incoming call starts. Default settings are restored after
# call is answered or rejected. Page scan interval is much shorter and page
# scan type changed to interlaced. Such allows faster connection initiated
# by a headset.
FastConnectable=false
# Just an example of potential config options for the other interfaces
[A2DP]
SBCSources=1
MPEG12Sources=0
# end copy/paste
Save the file with [CTRL-S] and reboot. You should now be able to set up and use your Bluetooth audio device.
If copy-and-paste doesn't work for you, I have created a Dropbox that includes all the Bluetooth-related .conf files I could find in a tarball...
