No sound in Firefox 84 using Jack

The problem is Firefox does not connect to system output node automatically as always.

If I use Catia to connect firefox output node to system manually, I get audio again.

I use

firefox --enable-jack

Re: No sound in Firefox 84 using Jack

Same issue here, didn't change with Firefox 85 (except that I can't play YT videos anymore at all right now ... not sure if that's related to the fact that it can't connect to the sound output ?).

All the other browsers just use alsa directly, and the alsa-jack plugin works like a charm and automatically connects. I think that was the default behaviour of FF until recently ? Not sure when
it stopped working ...

What's especially annoying is that FF starts a new JACK client everytime you pause/restart the video, so you can't even pause, connect manually, and resume ... so at this stage, if you're using
JACK, then FF is essentially useless.

Not sure if that's worth opening a bug ticket ?
EDIT: there already is one: https://bugs.archlinux.org/task/69014

Another Edit:

this works even though it's not super convenient: https://github.com/SpotlightKid/jack-matchmaker

Re: No sound in Firefox 84 using Jack

You can probably use jack-matchmaker or jack_autoconnect-git to autoconnect the ports.

Edit: So you found that. Another possibility may be to use pipewire as your sound server, and configure jack and pulse clients to use it. Then run firefox in pulseaudio mode.

Firefox 85 works perfectly on my system. I am using jack2 and just throwing blind could this be a dbus issue?
Also does pavucontrol produce a firefox-audio sink when playing something?

Re: No sound in Firefox 84 using Jack

Just to clarify, this happens in a scenario where you're NOT using PulseAudio, just Jack (Jack2 in my case) on top of plain ALSA.

Tbh I have no experience with PulseAudio ... haven't had it installed in a decade or so. Until FF83 that worked perfectly fine for my needs, but now it's a bit broken.
