i'm trying to find out about making these settings persistent in the pulseaudio and xbmc irc channels, could not find anything about it in the manpages

it really is a weird one, every command that can be used with pactl seems to have it's implementation in pacmd and therefore is in the pa-cli-syntax and can be used in the config files.
just the set-sink-formats command does not seem to have a command in pacmd

EDIT: i now use a workaround and call a sh script via the upstart service which first calls pactl and sets the parameters and then starts xbmc. works for now.
