sseneca [1] filed a deletion request for scream-alsa [2]: From a comment on its page:

Hey, scream 3.5 is out which merges the pulse and alsa binaries. I've pushed it to the "scream" package

There is no longer any use for this package, so it should be deleted. Users should instead install the `scream` package from the AUR. [1] https://aur.archlinux.org/account/sseneca/ [2] https://aur.archlinux.org/pkgbase/scream-alsa/
