after reading
http://lists.apple.com/archives/coreaudio-api/2003/Aug/msg00167.htmli'm curious as to the meaning of this error for the iphone and to check if i'm doing things correctly
after building a graph looking like
waveplayer -> delay -> mixer -> ioremote
each node being an audio unit, with delay processing input and thus using a callback that "pulls" data using AudioUnitRender(args...).
i am currently creating and initializing (setup input/ouput stream and callback) and then connecting
all the nodes, using AUGraphConnectNodeInput(args...).
i get the error when connecting the waveplayer to the delay unit.
there is no error constant in AUComponent.h and so on the off chance, i ignored the error and.....everything works.
