No Sound In Ubuntu 16.04!

Question

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.

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](https://wiki.ubuntu.com/DebuggingSoundProblems) 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
