[FirefoxNightly][FYI] - Pulseaudio output

[antenore]

This is just informational as it may be of iterest

In the official Firefox flatpak, with pulse audio and multiple output devices, I was not able in any way to choose the output device of my choice, even changing the default one was not working.

Finally I've test your Nigthly build and it works perfectly :-)

Thanks a lot and if you need some tests around Pulseaudio let me know
