ArchangeGabriel [1] filed a deletion request for bs1770gain-debian-git [2]:
This package is useless now that https://aur.archlinux.org/packages/bs1770gain exists. It was building from Debian because upstream used to do wrong things in build system, but that is no longer the case and Debian use upstream tarball as well now.
