Try turning the various input levels up and eventually one of them should start receiving some input. Some of them are related to each other and the relationships seem to vary between sound hardware; you need to have this one and that one both active to get input, but not this other one over here. Experiment with the levels and you'll find out which combination works. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com
