The issue I have is that, when trying to connect my bluetooth to my laptop (under Xubuntu 16.04), the speakers pair well, but once they are paired, I go on to click on "Audio sink", and I immediately get this error message :

Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol not available.

I have tried every solution I found online but none of them work, thank you if have a solution to this problem :)

  • Please add the output of: `apt --installed list | grep pulseaudio-module-bluetooth`, and then have a look at [Bluetooth module for PulseAudio sound server](https://apps.ubuntu.com/cat/applications/pulseaudio-module-bluetooth/) and [Arch - Bluetooth headset](https://wiki.archlinux.org/index.php/Bluetooth_headset#Headset_via_Bluez5.2FPulseAudio), and lastly [Pulseaudio not detecting bluetooth headset automatically](http://askubuntu.com/questions/366032/pulseaudio-not-detecting-bluetooth-headset-automatically) – eyoung100 Jun 30 '16 at 17:56
  • After the two commands you said I found I didn't have pulseaudio-module-bluetooth installed, so I installed it but it didn't change anything. I had already tried the solutions from the threads you mentionned. – Lilian A Jun 30 '16 at 18:19
  • Then install all the items listed in the Arch link. More than one is missing, and then retry. – eyoung100 Jun 30 '16 at 18:20
  • When I try to install them, I get " Unable to locate package [package] " with all of them except for the the package 'bluez'. I suppose I have to add a repository, but which one? Thank you. – Lilian A Jun 30 '16 at 18:28
  • While I look up the equivalent packages for Ubuntu, do the `pactl` commands in [Bluetooth audio sink refuses to connect in Ubuntu 14.04 (bluez, blueman)](http://askubuntu.com/questions/768250/bluetooth-audio-sink-refuses-to-connect-in-ubuntu-14-04-bluez-blueman) help or have you tried these? – eyoung100 Jun 30 '16 at 18:47
  • Both of these commands get me the message "Failure: Module initialization failed". Thanks for taking the time to help me by the way :) – Lilian A Jun 30 '16 at 18:53
  • Please provide and do the information I've requested of you in my answer. – eyoung100 Jun 30 '16 at 20:31

Let's start here, as these comments are getting out of control. I'll provide what I need, and you can either edit my Answer, or edit your question. I realize PulseAudio and bluetooth aren't necessarily related, but I want to make sure that all the other pieces are properly fresh.

Starting With A Clean Slate

Let's clean out PulseAudio's Configuration and Installation so we all start on a clean slate:

  1. If you are using Ubuntu 12.04 LTS (Precise Pangolin) or later, try this first: killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse*
  2. Issue: pulseaudio -k
  3. Remove your particular desktop, in case you aren't using the default desktop. Sorry, but I need a Baseline. Stop after the clean command. Before rebooting, let's remove PulseAudio. See Step 4.
  4. To remove and reinstall PulseAudio issue: sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install pavucontrol linux-sound-base alsa-base alsa-utils lightdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils lightdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; ubuntu-support-status
  5. Disconnect all Bluetooth devices.
  6. Reboot.
  7. Reinstall Unity, and Ubuntu Desktop. See the last of the post I linked in Step 3. At this point, you should have audio in hardware speakers.
  8. Enable Unlimited Scrolling in your Terminal: Start a new terminal, and click Edit > Profiles > "Default" profile > Scrolling. Choose "Unlimited" as scrolling option. Click Close and Close again.
  9. Verify or add your user to the following groups using usermod -aG: pulse, audio, pulse-access, pulse-rt, video: cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami

Provide Information About ALSA and PulseAudio

  1. Download the ALSA script: wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh.
  2. Provide information here about ALSA: bash alsa-info.sh --stdout.
  3. Provide the following information about your devices: cat /proc/asound/{version,cards,devices,hwdep,pcm,seq/clients}; sudo rm /etc/asound.conf; sudo rm -r ~/.pulse ~/.asound* ;sudo rm ~/.pulse-cookie; sudo apt-get update; sudo apt-get install aptitude; sudo aptitude install paman gnome-alsamixer libasound2-plugins padevchooser libsdl1.2debian-pulseaudio; sudo lshw -short;ls -lart /dev/snd; find /lib/modules/uname -r| grep snd ;cat /dev/sndstat; lspci -nn; lsusb; sudo which alsactl; sudo fuser -v /dev/dsp /dev/snd/* ; dpkg -S bin/slmodemd; dmesg | egrep 'EMU|probe|emu|ALSA|alsa|ac97|udi|snd|ound|irmware'; sudo /etc/init.d/sl-modem-daemon status; sudo grep model /etc/modprobe.d/* ; sudo dmidecode|egrep 'anufact|roduct|erial|elease'; lsmod | egrep 'snd|usb|midi|udio'; pacmd list-sinks; aplay -l; sudo alsa force-reload; ubuntu-support-status ; sudo lshw -C sound
  4. Provide a PulseAudio startup log: sudo gedit /etc/pulse/client.conf. Add extra-arguments = -vvvv --log-target=newfile:/tmp/pulseverbose.log --log-time=1 to the End of the file. Reboot && Post the content of the log here.

Provide Information on Bluetooth Applications

  1. apt-cache policy pulseaudio.
  2. apt-cache policy bluez.
  3. apt-cache policy blueman.
  4. apt-cache policy pulseaudio-module-bluetooth.
  5. Verify your Ubuntu release: lsb_release -rd
  6. Post the contents of /etc/pulse/default.pa.

I followed this, and it worked even though it wouldn't work multiple times. I think it is because I didn't properly close every program involved (blueman/pulseaudio) before executing the command
