Any idea on how to get rid of this connection refused issue?
Hi Kevin
Just for the record, I’m relatively new to this whole thing, so at this point I’m just shooting from the hip trying to help.
Regarding the multiple supervisor images, I also noticed that I had it last week, and I got rid of it executing the Docker command below. Note that according to the Docker documentation this will remove all images that are not linked to running containers (!), so be careful that you don’t loose something important.
# Delete Docker Images not linked to a running Container.
docker image prune
The actual Home Assistant container is homeassistant, so what is the home_assistant container? It is not running, so in theory it should not be a problem, but just to eliminate possible causes, and if you don’t use it anymore, can you remove the container? Try
docker rm home_assistant
About the connection refused problem…
What I miss in your hassio_audio process list is the PulseAudio service, shown below.
pulseaudio --system -vvv --disallow-exit --exit-idle-time=-1 --disable-shm
For your reference, below is the processes that are running in hassio_audio in my environment:
docker exec -it hassio_audio ps -ef
PID USER TIME COMMAND
1 root 0:00 s6-svscan -t0 /var/run/s6/services
35 root 0:00 s6-supervise s6-fdholderd
571 root 0:00 s6-supervise alsa
572 root 0:00 s6-supervise pulseaudio
575 root 0:00 bash /usr/bin/bashio ./run
576 root 1:52 pulseaudio --system -vvv --disallow-exit --exit-idle-time=-1 --disable-shm
601 root 0:00 bash /usr/bin/bashio ./run
602 root 0:00 udevadm monitor --subsystem-match=sound
610 root 0:00 bash
619 root 0:00 ps -ef
Can you see any errors in the hassio_audio container logs why the PulseAudio process fails to start? Are you sure you are not experiencing the problem that started this thread, and if yes did you implement the solution provided by Dominik, as explained here?
docker logs -f hassio_audio
Are you running this on a RPi, or something else? Are you actually using audio on this device, either in Home Assistant or on the device itself? Can you make sure that nothing is using audio when you are executing the commands?
Ok, you can execute commands in the container, so it looks like PulseAudio and the “pactl” commands are causing the error.
Can you try to run a Bash shell in the container, and then from this session try to list the loaded modules and try to load the “suspend” module? I see you are running Portainer… you can also open a console session in the Container from the Portainer UI.
# Connect and run a Bash shell in the hassio_audio container, or use Portainer.
docker exec -it hassio_audio bash
# If successful, you should now be root in a Bash shell in the hassio_audio container.
# Confirm who you are, then try to execute the "pactl" commands again.
whoami
ps -ef | grep pulse
# If the PulseAudio process is running (look for "pulseaudio --system -vvv ...." )
# then try to run the "pactl" command as root directly from inside the container
pactl list modules
pactl load-module module-suspend-on-idle
# kill the PulseAudio process. It should be automatically restarted immediately again. Then try "pactl" again.
kill <PID>
Hi JoFie, thanks for your time!
I’m running everything on a RPi4b and I don’t use audio at all. I implemented Dominik solution without luck.
home_assistant was coming from a docker-compose (I’m using IOTStack). I removed it but still have the same problem.

I’ll reinstall everything…starting with hass.io first, make sure I don’t have those errors and then IOTstack.
Thank you for your help!
Kevin
I also used IOTstack to set up my environment.
Maybe the difference is in how you added Home Assistant? I did not add Home Assistant from the IOTStack menu, so it is not in my IOTstack docker-compose.yaml. I added it afterwards (maybe following similar steps as the HA install part in this guide, I can’t remember). IOTstack also changed since I did it, back then it was still managed by a South African guy named Graham Garner.
You can also try to search for or post your question in the IOTstack discord forum.
To me the problem is that PulseAudio is not running in your hassio_audio, and you must figure out why that is. Is it indeed in a “boot loop”, as this thread title describes? If you say Dominik’s solution did not help, is it still in a boot loop/continuously trying to restart?
What is the date in your hassio_audio, is it the correct date?
docker exec -it hassio_audio date
When I kill the PulseAudio process in my container, it is automatically and almost immediately restarted. It uses the runtime parameters specified in “/run/s6/services/pulseaudio/run”, you can change it before killing the PulseAudio process so it uses your new parameters when it restarts.
e.g. to show a timestamp in the logs add " --log-time=yes"
The default parameters are defined in “/etc/pulse/daemon.conf”
But a different question… if the hassio_audio container does not flood your logs with errors, and it has no CPU usage, and you also don’t use audio in Home Assistant, then what is the concern if it does not work?
Hi Johan,
I followed your mail and the remaining post thread.

The latter is corrupted. It does not show the date correctly.
What is next step? Do you think a re-installation of complete system including Rpi4 - RaspiOS lite (buster) 32-bit installation will help to solve this issue?
It is now solved. I followed the solution in this thread like

That is totally different with my part in this thread.

The problem is clear, we must just fix it. And with any luck the solution provided earlier by Dominik should do the trick.
The problem is the " clock_gettime()" error:
# from the hassio_audio logs:
...
E: [pulseaudio] core-rtclock.c: Assertion 'clock_gettime(CLOCK_REALTIME, &ts) == 0' failed at ../src/pulsecore/core-rtclock.c:93, function pa_rtclock_get(). Aborting.
...
# the date is not set in hassio_audio (as result of above error):
docker exec -it hassio_audio date
Sun - 40447 20480:16:-1227370880 -1225953501
.
Below is the same solution provided by Dominik, I just wrote the steps in more detail.
-
Download the “
seccomp”default.jsonfile from Github:
https://github.com/moby/moby/blob/bc6f4cc7032544553d2304a5b47ba235dbfe5b9c/profiles/seccomp/default.json -
Copy the file to the Home Assistant host (Raspberry Pi), and put it in
/etc/docker/ -
Edit this newly created file,
/etc/docker/default.json.
In the second line replace
"SCMP_ACT_ERRNO"
with
"SCMP_ACT_TRACE" -
Then also edit this file,
/etc/docker/daemon.json.
Add the text below between the two existing lines.
(copy the line exactly as shown here, including the comma at the end)"seccomp-profile": "/etc/docker/default.json", -
Reboot, and then check if PulseAudio starts correctly in
hassio_audio.
Easiest place to start is to confirm the date inhassio_audiois correct.
Also check thehassio_audiologs:
docker logs hassio_audio
and see if the PulseAudio suspend module can be loaded successfully:docker exec -it hassio_audio pactl load-module module-suspend-on-idle
Voilà!
Once hassio_audio starts ok, also confirm that you are not suffering from another problem, namely hassio_audio consuming excessive CPU (for an idle container), up to 16% on my RPi 4. If that is the case, then consider to implement this shell script to suspend PulseAudio in hassio_audio whenever the container is (re)started.
Below is what these files look like in my setup, as reference:
# Contents of the /etc/docker/ directory:
ls -l /etc/docker/
total 32
-rw-r--r-- 1 root root 118 Feb 22 11:51 daemon.json
-rw-r--r-- 1 root root 97 Feb 19 16:29 daemon.json.json-driver
-rwxr--r-- 1 root root 13735 Feb 22 12:09 default.json
-rw------- 1 root root 244 Oct 24 17:58 key.json
# First 10 records of default.json (note "TRACE"):
head /etc/docker/default.json
{
"defaultAction": "SCMP_ACT_TRACE",
"archMap": [
{
"architecture": "SCMP_ARCH_X86_64",
"subArchitectures": [
"SCMP_ARCH_X86",
"SCMP_ARCH_X32"
]
},
# Content of /etc/docker/daemon.json (note the line starting with "seccomp"):
cat /etc/docker/daemon.json
{
"log-driver": "journald",
"seccomp-profile": "/etc/docker/default.json",
"storage-driver": "overlay2"
}
.
Below is the output when the PulseAudio module is loaded in hassio_audio.

This fixed the issue. Thanks.
Dominik - phantastic! Saved me hours of debugging and frustration. Thank you.
Got to hug u… it been months i try to fix this.
I have hassos and just found this issue on my Pi4. The workaround is not working - I can’t copy anything to /etc/docker on host since it’s ro filesystem.
So, what next?
Can you copy and paste the system health section from the Configuration > Info page?

Hello, thanks for posting the fix. However, on my system (RPI4 with Rasbian) there is no /etc/docker/daemon.json file. What do I do in this case?
I’ve just created a new daemon.json file with 3 lines and it all worked for me! Thanks a lot again for this solution.
Mr. Weiland, respect for the sleuthing work!
I got an alert today that one of my filesystems was getting full and when I looked at it I found the hassio_audio container generated about 1GB of useless logs each day since PI day (03.14). All of the log entries relate to this issue with "Assertion 'clock_gettime(CLOCK_REALTIME, &ts) == 0' failed", it repeats every second. And yes, it also uses about 15-20% CPU time.
I quickly found this page and I am really thankful you already identified the cause, and you also found a workaround.
One question for you please, if you don’t mind: do you know which 32-bit time syscalls alpine needs if the 64-bit ones are not available? I’m asking because I’d like to configure only the hassio_audio container to have access to these (and not to all syscalls), while keeping the other containers, well, “contained”, as they currently are. It can be easily done using the " --security-opt" parameter, see “Pass a profile for a container” at Seccomp security profiles for Docker | Docker Documentation
While your approach obviously works what you did is you probably allowed all containers access to all syscalls, essentially disabling docker security capabilities for all containers. I suppose you could have instead run only hassio_audio without the default seccomp profile by using --security-opt seccomp=unconfined
But I see no reason not to go just one step further and allow hassio_audio access only to the time functions it needs, and nothing else.
[Later edit]: I managed to identify the 19 64-bit syscalls related to time - they conveniently all have “time64” in the name. So I downloaded the default.json Docker seccomp security profile and I set only those 19 syscalls to SCMP_ACT_TRACE (I left the defaultAction for all other syscalls to SCMP_ACT_ERRNO) and it works - date returns the correct value and ping works, too, and hassio_audio is not in a loop anymore.
Steps to replicate when running on raspbian:
- Download the default.json Docker seccomp security profile as
/etc/docker/default.json - Delete the following 19 lines in the file (they are not all in a single sequence like here):
"clock_adjtime64",
"clock_getres_time64",
"clock_gettime64",
"clock_nanosleep_time64",
"futex_time64",
"io_pgetevents_time64",
"mq_timedreceive_time64",
"mq_timedsend_time64",
"ppoll_time64",
"pselect6_time64",
"recvmmsg_time64",
"rt_sigtimedwait_time64",
"sched_rr_get_interval_time64",
"semtimedop_time64",
"timer_gettime64",
"timer_settime64",
"timerfd_gettime64",
"timerfd_settime64",
"utimensat_time64",
- Add the following section right below the line
"syscalls": [(the blank space at the beginning of each line is made of TABs, not spaces):
{
"names": [
"clock_adjtime64",
"clock_getres_time64",
"clock_gettime64",
"clock_nanosleep_time64",
"futex_time64",
"io_pgetevents_time64",
"mq_timedreceive_time64",
"mq_timedsend_time64",
"ppoll_time64",
"pselect6_time64",
"recvmmsg_time64",
"rt_sigtimedwait_time64",
"sched_rr_get_interval_time64",
"semtimedop_time64",
"timer_gettime64",
"timer_settime64",
"timerfd_gettime64",
"timerfd_settime64",
"utimensat_time64"
],
"action": "SCMP_ACT_TRACE",
"args": [],
"comment": "Invoke a ptracer to make a decision or set errno to -ENOSYS",
"includes": {},
"excludes": {}
},
- Edit
/lib/systemd/system/docker.serviceand change the line
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
to
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --seccomp-profile /etc/docker/default.json
- Completely restart dockerd (or reboot, it’s simpler) and after that the hassio_audio stops (with a different error
) but it’s not in a loop anymore
I wish there was a portainer option to add --security-opt seccomp=/etc/docker/default.json for a single container (i.e. hassio_audio) and not as the default for all containers but there isn’t one yet. Hopefully, soon, I saw they reopened the feature request 3 days ago:
Cheers!
BTW, this issue seems to be fixed upstream since June-July 2020 in docker 19.03.9 and libseccomp 2.4.2.
On Raspbian 10 (buster) the current version of docker is 20.10.6, however libseccomp2 is still only 2.3.3-4
Below are some pointers.
“It looks like with the release of Docker 19.03.11 this has been addressed, at least on native hardware running a 5.x kernel.
[…]
Edit: It looks like this fix is comprehensive with this new version of Docker this is no longer an issue even on a host running an old 4.x series kernel.”
FAQ - LinuxServer.io has some options:
Option 2 Manually install an updated version of the library with dpkg [please note, on gitlab alpinelinux org issue 12091 somebody mentioned “This workaround makes my Raspberry in kernel panic”]
Option 3 Add the backports repo for DebianBuster
I have some news for you folks.
With the code down below you can install buster-backports and update your raspberrys libseccomp2 to version 2.4.4-1.
I think it is the best solution and I think it makes the workaround in the docker file unnecessary…
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 04EE7237B7D453EC 648ACFD622F3D138
echo "deb http://deb.debian.org/debian buster-backports main" | sudo tee -a /etc/apt/sources.list.d/buster-backports.list
sudo apt update
sudo apt install -t buster-backports libseccomp2
