Discontinuities in loudspeaker output with ambisonic input

Coding ambisonic input and rendering to loudspeakers at the decoder produces output with discontinuities. These seem to occur in blocks of 240 samples.

This is easiest to see and hear in harmonically rich tonal vectors (eg. Vocals).

This was found with the following command lines:
