I have noticed that this problem has been asked about many times but none of the answers that I have seen so far work for me.

Today in the morning I went to my computer and tried listening to some music but there was no sound. At first I just thought that volume was low or that it was muted but when I tried to turn up the volume it didn't work. I tried looking around the Internet for solutions but sadly nothing works.

Just kept on going with the same error for 6826 times.

  • What is the manufacturer and model of your computer? – Nick Weinberg Jul 10 '16 at 22:35
  • Manufacturer is HP and the model is a ProBook –  Jul 10 '16 at 22:36
  • Do you know which Probook? – Nick Weinberg Jul 10 '16 at 22:37
  • Its a Probook 455 G3 Notebook –  Jul 10 '16 at 22:38
  • Possibly related to http://askubuntu.com/questions/700167/no-sound-on-ubuntu-15-10 – Nick Weinberg Jul 10 '16 at 22:40
  • No I dont think so my situation is different –  Jul 10 '16 at 22:45
  • Open a terminal (press Ctrl+Alt+T) and run pavucontrol. When a window appears, go to the Configuration tab. Is your audio device set to either output or duplex? Go to the Output Devices tab and ensure that the Show list at the bottom of the window is set to All Output Devices. Is the volume level for your audio device in that window adjustable? – Olathe Jul 10 '16 at 23:23
  • @Olathe it did not work for me and when I do run pavucontrol it just opens a window and says that there is something wrong with the server. –  Jul 10 '16 at 23:36
  • OK, close that window, and run rm -r ~/.config/pulse; pulseaudio -k; sleep 15; sudo service pulseaudio restart, wait a few minutes, and test the sound. If it's still broken, run fgrep -i pulse /var/log/syslog, edit your question, and paste the results. – Olathe Jul 11 '16 at 00:00
  • @Olathe that also didn't work well the first command doesn't work. When I run the first command I get E: [pulseaudio] main.c: Failed to kill daemon: No such process –  Jul 11 '16 at 13:55
  • Yeah, I think the problem is that the PulseAudio server has trouble when it starts up. Try sudo service pulseaudio restart, wait a few minutes, then paste the results of fgrep -i pulse /var/log/syslog into your question. – Olathe Jul 11 '16 at 18:58
  • @Olathe again just failure nothing happened when I put in the first command all what was that had me put in password and thats it nothing really did happen. When I put in the second one just failure occurred. –  Jul 11 '16 at 20:18
  • I hope this sound debug wiki helps you. – gwarah Jul 11 '16 at 20:51

It appears that that there is a bug report filed for this which might or might not be related to Skype.

The problem

The error message mentions that there's a problem with a PulseAudio module.

Solution 1: disabling the module

If you'd like to try disabling the module, which might make Bluetooth audio not work, open a terminal (press Ctrl+Alt+T), and run the following:

sudo sed -i 's/^load-module module-bluetooth-policy/#load-module module-bluetooth-policy/' /etc/pulse/default.pa
sudo service pulseaudio restart
sleep 15
pulseaudio -k
pulseaudio --start
pavucontrol

If the PulseAudio volume control shows up properly, you should have sound.

Reenabling the module

If that doesn't fix it, open a terminal and run:

sudo sed -i 's/^#load-module module-bluetooth-policy/load-module module-bluetooth-policy/' /etc/pulse/default.pa
sudo service pulseaudio restart
sleep 15
pulseaudio -k
pulseaudio --start

Solution 2: reinstalling the Bluetooth module

If you'd like to try reinstalling Ubuntu's version of the module, which might make Skype not work, open a terminal (press Ctrl+Alt+T) and run:

sudo apt update
sudo apt install --reinstall pulseaudio-module-bluetooth
sudo service pulseaudio restart
sleep 15
pulseaudio -k
pulseaudio --start
pavucontrol

If the PulseAudio volume control shows up properly, you should have sound.

  • sorry but it did not not the first or second solution. When I put in pulseaudio -k I get an erroe saying E: [pulseaudio] main.c: Failed to kill daemon: No such process –  Jul 12 '16 at 02:15
  • Please put the results of fgrep -i pulse /var/log/syslog in your question. It might have a new error. – Olathe Jul 12 '16 at 02:18
  • same error form last time when I run fpreg -i pulse /var/log/syslog the results were Jul 11 18:21:26 d3faulto-comp pulseaudio[13229]: [pulseaudio] module.c: Failed to open module "module-bluetooth-policy". Jul 11 18:21:26 d3faulto-comp pulseaudio[13229]: [pulseaudio] main.c: Module load failed. Jul 11 18:21:26 d3faulto-comp pulseaudio[13229]: [pulseaudio] main.c: Failed to initialize daemon. –  Jul 12 '16 at 02:21
  • OK, that might be a bit different. Try the new solution 1. If it fails, see what fgrep -i pulse /var/log/syslog says. – Olathe Jul 12 '16 at 02:29
  • whats the new solution? –  Jul 12 '16 at 02:39
  • I replaced solution 1 above so that it uses sudo sed instead of sudo mv. It should make it not even try to load it. – Olathe Jul 12 '16 at 02:41
  • once again failure with the same error when I run pulseaudio -k and when I run fgrep -i pulse /var/log/syslog it says Jul 11 18:21:26 d3faulto-comp pulseaudio[13229]: [pulseaudio] module.c: Failed to open module "module-bluetooth-policy". Jul 11 18:21:26 d3faulto-comp pulseaudio[13229]: [pulseaudio] main.c: Module load failed. Jul 11 18:21:26 d3faulto-comp pulseaudio[13229]: [pulseaudio] main.c: Failed to initialize daemon. Jul 11 18:21:26 d3faulto-comp pulseaudio[13226]: [pulseaudio] main.c: Daemon startup failed. –  Jul 12 '16 at 02:45
  • Any chance this will ever be resolved? – Demiurg Apr 17 '17 at 11:57
