Firefox-52.0 no sound on YouTube

[john123]

Hi,

After recent Firefox update, there is no sound on YT.  I have sound on other players in Firefox,  just not on YT. 

And there is  notification that needs to be installed pulseaudio.

Is it just me? I don't have pulseaudio installed.

It is firefox-bin latest version 52.0. And adobe-flash plugin.

Sound output in pre-compiled firefox >=52.0 requires pulseaudio.
I use this method : https://wiki.archlinux.org/index.php/PulseAudio/Examples#PulseAudio_as_a_minimal_unintrusive_dumb_pipe_to_ALSA
Required USE="-alsa-plugin" in pulseaudio with my profile.

Cardinal thanks. Works like a charm.

I assume that once the source package becomes available the -pulseaudio USE flag will still work.  I'm not installing a stutter inducing sound shim to appease Mozilla developers.
