Original GitHub issue: https://github.com/netblue30/firejail/issues/430

Hi netblue30. I've noticed a strange occurence when using Firefox and firejail: whenever I play a video in Firefox, my entire system sounds applet crashes and I have to reboot the computer to get the system sounds back. I can continue to play other sounds, such as those in Pidgin, but my system sounds are lost.

I am not using a custom Firefox profile, I'm using firejail 0.9.38, and I have used a fresh Firefox profile to ensure that this wasn't some incompatibility between a Firefox add-on and firejail. My OS is Linux Mint 17.3 64-bit with the Cinnamon desktop, using kernel 3.19.0-32. The precise command I use to launch Firefox is firejail firefox.
(When not using firejail, I can play videos normally in Firefox and not lose sound.)

This is the output I get:
Reading profile /etc/firejail/firefox.profile
Reading profile /etc/firejail/disable-mgmt.inc
Reading profile /etc/firejail/disable-secret.inc
Reading profile /etc/firejail/disable-common.inc

This bit crops up when I attempt to play a video:

ERROR: ld.so: object '/usr/lib/i386-linux-gnu/firejail/libtracelog.so' from /etc/ld.so.preload cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

I noticed in particular that /usr/lib/i386-linux-gnu/firejail/libtracelog.so can't be preloaded in any of these instances.

I [asked for help on the Linux mint forums first](https://forums.linuxmint.com/viewtopic. ... 8&t=219853) and, after some debugging, was advised to contact you directly on GitHub.

Thanks in advance!

I think you have a firejail 32-bit installed on a 64-bit computer. I would uninstall it and put a amd64 version on from https://sourceforge.net/projects/firejail/files/firejail/

A possible workaround if you cannot install a new firejail: in a text editor open as root /etc/firejail/firefox.profile file (sudo vim /etc/firejail/firefox.profile or any other editor, but make sure you use sudo), and comment out tracelog line. It should look something like this:

# tracelog

This should solve all the errors you get. Try it out and let me know, we'll take it from there if you still have problems.

     I did just as you asked and my system sounds applet still crashed.
     I installed firejail_0.9.40-rc1_1_amd64.deb which I had no

problems installing.

     I ran it in the terminal, after it was installed, and this is

all that the terminal displayed:

Ok, next step is to configure PulseAudio. It has a problem in the later versions due to some feature they started configuring by default. This will get us one step closer. I have a description of the problem and the fix here: https://firejail.wordpress.com/support/known-problems/

Look at "PulseAudio 7.0 issue"
