Public bug reported:
Recently I was some implementing some LXC desktop environments and came
across a difference regarding Firefox when started from the CLI or
started from a Menu.
In my use-case I use the Pulseaudio module module-native-protocol-tcp in
the Host to allow the LXC desktops to redirect their sound/audio to the
Host's speakers.
in particular... this is done by adding the following to
/etc/pulse/system.pa & restarting Puluseaudio or rebooting once.
load-module module-native-protocol-tcp auth-ip-
acl=127.0.0.1;10.0.3.0/24
Then in each LXC container user's .bashrc I add:
export PULSE_SERVER=10.0.3.1
Which redirects sound in the LXC container to 10.0.3.1 which is the Host
& the Host's Pulseaudio server.
aplay /usr/share/sounds/alsa/Front_Center.wav tests that the sound is
directed to the Host Pulseaudio server ok and other apps like VLC work
fine also in the container.
However, I found that only with Firefox (and Chrome) launched from the
Ubuntu menu there was no sound/audio.
If I launched either Firefox or Chrome from the CLI where the User
environment had the PULSE_SERVER=10.0.3.1 then sound worked fine
(youtube for instance).
After digging around I found that launching from the Ubuntu menu doesn't
execute the Firefox binary directly but via a shell script in
/var/lib/firefox/firefox.sh.
If I add: "export PULSE_SERVER=10.0.3.1" to the top of firefox.sh
then Sound DOES work when launching Firefox in an LXC container by
clicking on its icon in the menu.
I decided to file a bug on this because I'd expect that the User
"environment" for Firefox should be the same whether launched from CLI
or from the menu.
