systemd management of DroidCam sound : PulseAudio profile set for ALSA loopback module

Using Gnome's systemd .scope units I have built a set of systemd user and system level services to manage DroidCam's use of ALSA snd-aloop module and PulseAudio source creation for an automated and less confusing start-up. This was developed on Ubuntu, but should be portable across other distro's that use the latest Gnome release.

Also in the same repo, I have created a PulseAudio profile-set for ALSA snd-aloop module and UDEV rules. Even if you don't want the full systemd approach these files can be used to better identify ALSA's snd-aloop module under PulseAudio's configuration tab inside 'pavucontrol'. This avoids having the ALSA snd-aloop module appear as a second 'Built-in Audio' card.
