Thank you for this
With Firefox 52+ dropping ALSA, thank you so much for this! This might be the only way to still use Firefox with ALSA.
This might be the only way to still use Firefox with ALSA.
It should be possible to make own build of Firefox with ALSA support enabled. As far as I know, there are no plans to remove ALSA code from libcubeb library, which is used by Firefox to play audio.
With Firefox 54 it is no longer possible to turn on ALSA support.
Just tried to build Firefox 54 from source with the following .mozconfig:
ac_add_options --enable-alsa
ac_add_options --disable-tests
Audio works without PulseAudio, by directly using ALSA. There is no need to disable sandboxing or something like that. In ALSA-enabled builds, paths required by userspace part of ALSA are in exception list already. So, it should work. What are your build options?
It doesn't work when you have browser.tabs.remote.force-enable = true. There is no sound. When this option is set to false it works.

I tested once again, now with this option set. Audio still works. Actually, that option did nothing, since I'm testing on an empty profile, so multiprocess mode is enabled.
@worldowner, how do you build Firefox? Are you sure you have --enable-alsa option set?
about:support says: Audio Backend alsa
so yes, I'm sure. I took PKGBUILD from Archlinux's abs, added ac_add_options --enable-alsa ac_add_options --disable-tests
and recompilled (makepkg) inside virtual machine (because I have access to powerful servers). I'm running this build on 2 different computers, one Intel based laptop, second AMD based desktop and result is the same. No sound when browser.tabs.remote.force-enable = true
It's enough to set this to false and restart Firefox to get sound back.
I double checked that just a minte ago.
sets browser.tabs.remote.autostart to false, restarts firefox... nope didn't work... in fact, I can't seem to be able to set that to false, it just creates a new key with .2 at the end, set to true...
sets browser.tabs.remote.autostart.2 to false, restarts firefox... CAN HEAR AGAIN
EDIT: don't do this. this technically disables the sandbox. instead, see #55.
@i-rinat Thanks for apulse! It's not always possible to build firefox from source, though, so apulse really helps here and with skype. Спасибо.
Just want to add another thank you. Will give me some time to run away from Firefox.
Another thank you for this project! I rebuilt Firefox with ALSA support on Gentoo, but it wasn't picking up the audio I/O settings other than the sample rate. apulse allows Firefox to pick-up an output device, though the sample rate is incorrect, which that is corrected with the plug interface.
