Original GitHub issue: https://github.com/netblue30/firejail/issues/1175

As the title said. I already tried without success those documented fixes:

https://firejail.wordpress.com/support/known-problems/#pulseaudio

I also try to upgrade to the latest version of Firejail (0.9.44.10) with no different results.

...and yes, the sound is working (and I do not have the pulseaudio dialog box) if I start Firefox without firejail.

Additional information:

My pulseaudio version: 9.0

Any suggestions? Thank you!

What pulseaudio dialog box are you talking about? One thing you can try is using firejail --ignore=<something> or commenting out everything from the firefox profile and slowly uncommenting stuff until you find the offending line.

The one in Firefox when it cannot detect a pulseaudio installation (because of the jail in my case):

https://lut.im/w8qbLWHcHy/GaxukY03tA43GCU0.png

commenting out everything from the firefox profile and slowly uncommenting stuff until you find the offending line.

I tried that and I have the issue even when all the options are commented out...

I'm really out of ideas on this issue.

Huh...I've literally never had that issue. Let's start with the basics: does firejail --noprofile firefox work? If so, let's create a new firejail profile in ~/.config/firejail/firefox.profile where we can start adding options. Start with seccomp and caps.drop all and let's work from there.

Nope and the sound is working perfectly if I start firefox in the terminal with just 'firefox'

Here's the error message I get multiple times in the terminal with 'firejail --noprofile firefox'

Huh, interesting. Which version of firefox?

Client failed to connect to the D-BUS daemon: Failed to connect to socket /run/user/1000/bus

Shouldn't really matter (I don't think it has anything to do with the pulseaudio issue).

OK, I just found my problem. I remember that I was also having a apparmor profile enabled for Firefox. I disable it and tried 'firejail --noprofile firefox' again...and it worked.

The thing is before Firefox 52, I could get sound in Firefox even if I was using both Firejail and Apparmor. Apparmor was "connecting" to pulseaudio and Firefox in Firejail was using ALSA. So the sound was working for me with the 2 active sandboxes. However, Firefox stopped supporting ALSA in version 52 and that's when my sound problem began...Yeah I should have thought of this sooner. Sorry and thanks for the help!

@BytesTuner With the apparmor profile disabled, does firejail firefox have audio?

Yes. Now with Firefox 52, I will have to choose between using Firejail or apparmor. I cannot use both at the same time anymore if I want sound from the browser.

It is very easy to solve this issue. You just need to add a line
/run/firejail/mnt/pulse/client.conf r,
to /etc/apparmor.d/local/usr.bin.chromium-browser.

Does somebody have an idea how to solve this for ALL users? (Most users will probably not search in GitHub issues if they have a problem with PulseAudio).
What about what I proposed here: https://github.com/netblue30/firejail/issues/1487#issuecomment-328508519

(It is so easy to solve this, in my opinion it CAN'T be that it remains unsolved for 90 % of the users)
