How did you get the error code from the throw?
Im trying to do voice processing and track down an error so I know whats going wrong. I just get the following
AU (0x10811fb40): auou/vpio/appl, render err: 18,446,744,073,709,551,615
18446744073709551615 seems to be the max value for 64 bits...
What are you attaching the sink for?
