I imagine you will not have a pulseaudio process running, i.e. executing


 λ ps aux | grep pulseaudio
constan+     610  1.4  0.1 3120980 14064 ?       Ssl  мар10  80:22 /usr/bin/pulseaudio --daemonize=no --log-target=journal

will not give you a pulseaudio process, similar to the output I here. Also, usually pulseaudio is enabled as a "user" systemd service. I imagine, it might be different depending on a distro, but at least on Archlinux I can check on it as:


 λ systemctl status --user pulseaudio
