MarsSeed [1] filed a deletion request for volti [2]: Defunct Python2/Gtk2 based ALSA audio mixer, last released in 2010. [a] There are 30+ unfixed breaking issues, many of them predate the 2015 bug tracker migration from Google Code. [b] I recommend deletion, as there are working alternatives for this use case.
