Pulseaudio not working, daemon already running and no permission for home folder
Solution 1
I had the same problem, none of the top Google results helped, and I finally found a solution that worked: make sure your user is in the audio
group.
I added mine with the following command:
sudo addgroup $USER audio
Solution 2
I had similar issues:
- sound suddenly stopped
- not able to change output and input devices
- not recognized newly added sound adaptor
- none working microphone
- none working headphone
and found out that for some reasons multiple pulseaudio
servers were running by executing ps x | grep pulseaudio
. The following steps solved the problem:
- Kill all the instances with
killall pulseaudio
. - Start the daemone again with
pulseaudio
.
After that it worked again.
Solution 3
Had a similar issue where the attached USB audio device just played on 4 of the 8 output channels after update from Ubuntu 19.04 to 19.10. The pulseaudio log was
E: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: pa_pid_file_create() failed.
Deleting the files in ~/.config/pulse
and restarting the machine solves the issue
Solution 4
What did work for me :
Pulseaudio configuration's files in
~/.config/pulse
were like
589187e8155f40638e8344f0f9b0ab3c-*
Therefore I deleted them then I did
cp /etc/pulse/* ~/.config/pulse/
It works !

I'm using Ubuntu 16.04.4 LTS, and the sound "suddenly" stopped working. I have been playing around with the issue for some time, so it's possible that I added another layer of problems on top of the original one. The situation at the moment is the following:
pulseaudio
producesE: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: pa_pid_file_create() failed.
Running it as
sudo pulseaudio
:E: [pulseaudio] core-util.c: Home directory not accessible: Permission denied
Then, I tried the solution proposed by this question to fix the accessibility problem of the home directory:
sudo chown -R giovanni:giovanni /home/giovanni
but with no apparent effect. Running
pavucontrol
works fine.The output of
pulseaudio -vvvvv
is as following:I: [pulseaudio] main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted I: [pulseaudio] main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted D: [pulseaudio] core-rtclock.c: Timer slack is set to 50 us.

I: [pulseaudio] main.c: Running in system mode: no E: [pulseaudio] pid.c: Daemon already running. E: [pulseaudio] main.c: pa_pid_file_create() failed.
I tried to remove and reinstall pulseaudio (several times) but with no success. Also, I verified that there's no pulseaudio file in:
~/.config/autostart/
There are no files in:
/etc/X11/xinit/xinitrc.d/pulseaudio
/etc/xdg/autostart/pulseaudio-kde.desktop
There is a file in:
/etc/xdg/autostart/pulseaudio.desktop
I would be grateful for any suggestions on what to check or how to fix this issue. Thanks!

Giovanni De Gaetano almost 6 yearsThanks for the answer! This wasn't the problem in my case, as I already was a member of 'audio'.

Ben Creasy over 5 yearsThe user group
audio
is unlikely to be a fix, at least with modern Ubuntu - see wiki.archlinux.org/index.php/… which notes that it's used for accessing device files pre-systemd. More details at freedesktop.org/wiki/Software/systemd/multiseat particularly 71-seat.rules and 73-seat-late.rules that ship with systemd (thanks buhman from #pulseaudio IRC) -
Dzinic over 4 years@BenCreasy On the contrary, this ended up fixing a pulseaudio issue that I've been trying to fix for a month and a half now on 19.10.
