Hi everyone
I installed Mycroft in Docker recently and since then Pulseaudio is not starting on boot. I’m even having difficulties starting it manually as well. I’m not certain whether Mycroft is the culprit but that is the only change I’ve made and it coincides with the issue appearing, hence posting here.
Running Ubuntu Budgie 19.10. and the latest Docker image.
On boot, the Sound settings show no available audio device. I’ve done some searching online for issues with Pulseaudio not starting and tried the suggestions (removing the config, reinstalling pulse, checking Alsamixer) but to no avail. I can sometimes get the audio device to be recognised and get the audio working but it doesn’t stick on reboot.
Today I noticed that when I manually got pulse running, system sounds were playing, but not other media (e.g. YouTube).
Relative noob, so any suggesions welcome.
Thanks
Tony
Hi,
the docker image in itself shouldn’t™ be able to affect the systems pulseaudio settings as far as I understand.
Maybe there’s something dangerous with the recommended commandline for connecting the docker to the systems pulseaudio. Are you using the commandline suggested in the readme for launching the mycroft docker container?
The snaps thing got me thinking about the need for a docker image and forgot it existed.
Pulseaudio seems to be a bit funny in docker as from a google there seems to be a range of preference on how to employ.
I am going to give the docker image a go also as people ask from time to time about installing on ‘other’ images and docker is prob preferable than maybe native install but will see how it goes.
Don’t think things are happy

The docker image prob doesn’t work as think it assumes the host has pulseaudio running and you connect to the pulseaudio server of the host.
It doesn’t start a server that is for sure.
Its a bit big and cumbersome just to check alsa and pulseaudio so I did this.

pulseaudio is such a pain to run as root I started a conatiner running as pi.
pulseaudio --start runs fine but it doen’t pick up any cards
Which has me confused as aplay and arecord works in the container
I just copied a test wav https://file-examples.com/wp-content/uploads/2017/11/file_example_WAV_10MG.wav
startup.sh was just a horrid
#!/bin/bash
for (( ; ; ))
do
aplay file_example_WAV_10MG.wav
done
which doesn’t start because your not root… nope workdir is just not recursive
The docker image we have presumes you have pulseaudio running on the host but pulseaudio and also don’t seem to like each other in a docker container.
I can have startup.sh &running and if I pulseaudio --start it will not play the next loop pulseaudio -k and it suddenly starts to play.
I presume pulseaudio needs access to somthing somewhere so the cards arrive in a pacmd list
I will keep batting away but starting to think a totally contained docker container might be easier if we use apulse emulation rather tha pulseaudio for the docker container.
If I don’t I will totally forget about how docker works again, but its all new to me as with containers and VMs done loads over a long period of time but never had to mess with sound and to be honest confused.com
