Hello!

You're welcome, and welcome to Linux Lite and the forums.

It's always a good thing to have another way of doing things. When we came up with the original procedure, we were only interested in getting the stereo headsets playing.

> Now I have to discover if its possible to get more devices (aka BT KIVIO Headset) running at the same time on same dongle.

# Maximum number of connected HSP/HFP devices per adapter. Defaults to 1
MaxConnected=1

Changing this value increases the number of BT devices that can be connected at the same time. I'm interested in whether or not this would actually work, as I've never tried it myself. I've also noted the changes to make to the/usr/share/alsa/alsa.conf file...

Great tutorial mate, always glad to see more of this stuff. Just an FYI, you can use code tags to highlight the commands one needs to type.

[ code ]  sudo command -do-something [/ code ]

remove the spaces in the example, or you can use the # icon when highlighting text on the editor here on the forums to add the code tags.

Ave !

this is my very first post ever, so please be patient if I'm still not very confident ... Special thanks goes to N4RPS notes !
I am no expert on Linux but I hope this may be of some help to other LL mates with the same issues ;-) .

Requirement : ( see subject )

- Distro : Linux Lite 2.4 x64
- Kernel : Linux 4.1.0-040100-generic
- BT Port : USB Cambridge Silicon Radio, Ltd Bluetooth Dongle - ROCKETEK Bluetooth 4.0
- BT Speaker : EASYACC-MC

STEP A:
   
        Open a Terminal session (CRTL+ALT+T) and do the following :

   EDIT the audio.conf file

   $ sudo leafpad /etc/bluetooth/audio.conf  (root password)

   edit/add the below area in the configuration file as follows:

   [General]
   Enable = Source,Sink,Headset,Gateway,Control,Media
   #Disable = Socket                               ( REMARK ANY ACTION ON "SOCKET" EVERYWHERE )
   HFP=false                                    ( DISABLES HFP )
   [A2DP]
   SBCSources=1
   MPEG12Sources=0

   SAVE and close file

STEP B

   $ pacmd list-sources >Output.txt (enter)

   Search in output for a reference to your BT devicer and copy (ctrl+c) the "device.string"  parameter (port ?).

   properties:
      device.description = "Monitor of EasyAcc-MC"                            <== This is my BT Speaker
       device.class = "monitor"
      device.string = "5C:5A:5A:A6:03:CB"                                                  <== Copy what you get here
      device.api = "bluez"
      device.bus = "bluetooth"
      device.form_factor = "headset"
      bluez.path = "/org/bluez/1289/hci0/dev_5C_5A_5A_A6_03_CB"
      bluez.class = "0x240404"
      bluez.name = "EasyAcc-MC"
      device.icon_name = "audio-headset-bluetooth"
      device.intended_roles = "phone"

STEP C

   I then purged BLUEMAN and reinstall it. Sound silly, but this probably fixed some missing dependencies (need to ask someone who knows better)

   $ sudo apt-get purge blueman (root password)
   $ sudo apt-get install blueman (root password)

STEP D

   Then edit the ALSA configuration file :

   $ sudo leafpad /usr/share/alsa/alsa.conf (+root password)

   Add the following to the end of the configuration file :

   ================ ADDED below to END of alsa.conf file ============
   pcm.btheadset {
      type plug
      slave {
          pcm {
              type bluetooth
              device 5C:5A:5A:A6:03:CB                                                   <=== REPLACE WITH ADDRESS YOU COPIED/DISCOVERD
              profile "auto"
          }
      }
      hint {
          show on
          description "BT Headset"
      }
   }
   ctl.btheadset {
     type bluetooth
   }
   ================ ADDED above to END of alsa.conf file ============

   Save file and close.

STEP E :

   Activate your blueman interface and re-pair EASYACC-MC SPEAKER device with USB BT dongle.
        Be careful to select Audio Profile / High Fidelity Playback (A2DP) ... it may take a sec or 2 to sync.

   Playing music with Audacious, audio is crystal perfect !
   This works after re boot too ... for now ;-)
       
NOTES :

        Now I have to discover if its possible to get more devices (aka BT KIVIO Headset) running at the same time on same dongle.

        The headset work fine in exclusive mode (BR speaker excluded). 
 
Ad majora !
