My questions is probably stupid, but I want to multiply the payload

As a first step, I tried first replacing the memcpy with
for(int i = 0; i < samples_per_packet; i++) out[i] = in[i];
but that of course doesn't successfully replace the functionality?
Sure, why not? However, it probably be the solution with the best
performance. You could stick with the memcpy() and use a VOLK kernel
afterwards. But your solution seems correct.
