I've figured out why the samples are 'dropped'.
Using this set [0] of filter taps and performing a convolution with my input
sample stream. The first three samples are always multiplied with zero and are
ignored in the sum.
This behaviour seems inherent and not like a bug. But I think this behaviour
isn't not obvious if using the channel model block.
