Firefox requires PulseAudio to play any audio.

Firefox does NOT require pulseaudio to play audio.
You can substitute pulseaudio with apulse from AUR.
Depending on your hardware you may have to redirect the output of apulse.

apulse is minimal (and was buggy for me) pulseaudio implementation.

Sound works for me in Pale Moon, Firefox and Chromium without pulseaudio or apulse. I have these installed and the alsasound service is enabled in the default runlevel. I thought the Artix Firefox package is compiled without a requirement for pulseaudio, unlike the Firefox binary direct from Mozilla?
