It would greatly help us if you told what audloop* is supposed to be. Most likely it doent work because you idndt install whatever in way that the mayas built in python sees. So normal installers would mostly all fail to install stuff in way that would make maya see them. So you would need to point maya the rest of the way yourself.
Ok found info on google seem like i read the name worng (its very hard to copypaste titles). Anyway yes its simply not included in the maya installation of 2009 . Try a manual instal. In anyway the maya 2011 has a new enough distribution to have it included.
Very little uee for this insdide maya tough. If you want more usage info contact a board thats actually focused on audio stuff. Its not really thsi baords forte to tell yu how everything in python works.
PS. also its not considered good writing form to reference heading of something in the body text. If yoo talk about something in the text thet something has to be in the text.
