The APTX (HD) decoder decodes blocks of four (six) bytes to four
output samples. It makes no sense to handle incomplete blocks:
They would just lead to synchronization errors, in which case
the complete frame is discarded. So only handle complete blocks.
This also avoids reading from the packet's padding.
