MarsSeed [1] filed a deletion request for esd-oss [2]: Broken, unmaintained reduced functionality variant from 2019 of AUR/esound.
Only the latter one has direct dependents (consumers). Safe to delete this one. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/esd-oss/
