I just think the problem is that the filter doesn't get enough time to do
it's work. If there is a sleep in the aout core before running user modules
it should perhaps be shortened, but this is only a partial solution. I think
that for visualization to work properly they need to be in a separate
thread. Then the DoWork fuction only needs to do a memcpy of the buffer.
