No Sound with graphics-accelerated GUI app (Chrome) in LXD containers

NetSpasibo79 · June 1, 2020, 9:53pm

Greetings:

I originally encountered this issue when I was attempting to run Firefox inside of a LXD container (see link here):

No Sound with graphics-accelerated GUI apps in LXD containers

I followed Simos’ direction within that same thread and got Firefox working with sound.

Now, I have attempted to follow the same directions to create a Chrome LXD container using the x11 profile that works with the Firefox container but again, am faced with no sound. These are the errors that pop-up when I start chrome:

If you want to try an alternative, you can use pulseaudio networking:
https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Network/

In this case you simply create a proxy device for the port.
Set up a config in pulseaudio to allow only connect over 127.0.0.1.
Then you add an environment variable to .profile and every application that you open inside the container will use the pulseaudio server of your host.

This is a weird message. I would focus on this one.
Check the value of $PULSE_SERVER.

NetSpasibo79 · June 2, 2020, 6:36pm

:~$ $PULSE_SERVER

on the Host and in the Container did not produce any output

simos · June 2, 2020, 8:44pm

In the container run

export PULSE_SERVER="unix:/home/ubuntu/pulse-native"
pactl info

If this works, then the issue is with the container not setting up the variable PULSE_SERVER.

NetSpasibo79 · June 2, 2020, 8:57pm

So that worked in so much as I launched Chrome from within the container and was able to hear sound. Here is a pastebin of the output from your advice, through launch, including youtube.com, followed with closing chrome via the “x” in the upper righthand corner.

Thank you for all your help!

Well I decided to be cute and install Chrome in the existing Firefox container thinking “hey, if it works for firefox …” Well all that managed was to mess up the Firefox container and not it does not have sound. And, of course, since I don’t consider Firefox mission critical, I dont have a back-up

The error Firefox throws, now:

Setting PATH
Starting up Feral SSH tunnel
Starting Firefox
Sandbox: /tmp/.X11-unix/X0 is inaccessible (No such file or directory); can't isolate network namespace in content processes

(firefox:964): LIBDBUSMENU-GLIB-WARNING **: 19:20:23.738: Unable to get session bus: Failed to execute child process “dbus-launch” (No such file or directory)

NetSpasibo79 · June 14, 2020, 6:02pm

As an aside, I have not made any progress. If anyone has any advice I would greatly appreciate it. Thank you.

NetSpasibo79 · June 14, 2020, 10:39pm

I came to a solution though it is not stable (per Google).
The issue (as I understood it) was two fold:

Chrome cannot run with sudo privileges*
the lxc container cannot connect to the pulse without sudo privileges

The solution is to run Chrome with the “–no-sandbox” flag as a user with sudo privileges within the lxc container. However, this will cause problems with Chrome (and it says as much as it is running) with stability.

If anyone wants to investigate further I would love to see a work-around however I am marking this solved on my end as I am moving on. Thank you!

simos · June 15, 2020, 8:45am

Ok, let’s go.

(I use the lxc ubuntu mycontainer alias to get a shell into the container. See the Summary at See https://blog.simos.info/using-command-aliases-in-lxd-to-exec-a-shell/ on how to set it up yourself as well.)

$ lxc launch ubuntu:18.04 guicontainer --profile default --profile x11
Creating guicontainer
Starting guicontainer
$ lxc file push /usr/share/sounds/ubuntu/stereo/dialog-information.ogg guicontainer/home/ubuntu/
$ lxc ubuntu guicontainer
ubuntu@guicontainer:~$ pactl info                             # Both at version 32. 
Server String: unix:/home/ubuntu/pulse-native
Library Protocol Version: 32
Server Protocol Version: 32
Is Local: yes
...
ubuntu@guicontainer:~$ paplay dialog-information.ogg       # works for me.
ubuntu@guicontainer:~$ sudo apt install -y firefox 
ubuntu@guicontainer:~$ wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
ubuntu@guicontainer:~$ sudo apt install -y ./google-chrome-stable_current_amd64.deb

Having done that,

I am able to run Firefox and play videos from Youtube, with sound.
I am able to run Chrome and play videos from Youtube, with sound.

In Chrome, I get the warning and errors that you showed earlier. But it still works. Here are the warnings as soon as I start Google Chrome.

As soon as I play a video (that has audio), I get more of the following,

It looks to me that Chrome runs in an unfamiliar setup and complains hard. But still it works.

NetSpasibo79 · June 16, 2020, 11:53am

Simos:

Thank you for the response and I was able to replicate your process and achieve the same results. The only thing I was doing differently was that I was unawares of the the need (option?) to push the dialog-information.ogg file.

The other “problem” is that while I know much more than I knew even a few weeks ago, I still don’t know enough to provide comprehensive explanations of my situations. It is quite possible there is something I am overlooking when evaluating my issues.

Irrespective, thank you!

EDIT: On a far less important level, I’ve noticed that when a gui app is installed its appearance is “gnome.” Is there a way to install a gui app and force it to use a plasma aesthetic?

simos · June 16, 2020, 2:58pm

This is just an interim test to verify that things are working.

There are several ways to get a shell into a LXD container. Depending on the way, your shell may or may not be able to receive the PULSE_SERVER variable. Therefore, if pactl info gives you an error, it may be due to the shell not getting the PULSE_SERVER variable.

This is related to theming. I have not looked into this. There should be a way for the container to use the theming from the host.
