I was hoping you'd say the interpolation and/or decimation were some ridiculously large numbers. Since the block is only actually decimating, could you replace it in the code with an fir_filter_fff (or fft_filter_fff) just for testing purposes? That'll help us see if it's the rational resampler itself or something more general.
