pulseaudio does not start

Question

System: Linux Mint Cinnamon 18.2 Sonja

After I had some struggle to connect my bluetooth mouse with my notebook (see here), the system does not recognize any sound devices. Neither my inbuilt loudspeaker nor my inbuilt microphone will be shown in "start / system_settings / hardware / sound / output | input". The sound-applet in the panel (task-bar) also will not be shown.

I already reinstalled pulseaudio, still it gives me following error back:

alpha@Pavilion ~ $ pulseaudio 
E: [pulseaudio] main.c: Unknown command: module-bluetooth-policy
E: [pulseaudio] main.c: Failed to initialize daemon.
alpha@Pavilion ~ $ pulseaudio --start
E: [pulseaudio] main.c: Daemon startup failed.

Has anyone an idea how to fix pulseaudio?

Solution

It looks like i messed it up by myself. Luckily I found the problem:
As i mentioned before I had some struggle to connect my bluetooth mouse, so I made a couple of changes. Unfortunately I forgot to remove the previously inserted lines in /etc/pulse/default.pa, which were the following:

module-bluetooth-policy
module-bluez5-device
module-bluez5-discover

Aftere removing those lines and executing the following commands everything works fine again.

~$ sudo vim /etc/pulse/default.pa 
~$ ## remove the mentioned lines
~$ cd $HOME
~$ mkdir .pulse
~$ pulseaudio --kill
~$ pulseaudio --start
~$ sudo reboot now

i had a same issue, but i solved much easier: pulseaudio --start, pulseaudio -k, pulseaudio (got some errors but all fine), pulseaudio --start all worked !

this somehow solved my problem, i can hear audio now whenevr i change the sound bar on pavucontrol but I can't hear anything from my browsers.
