Wow. Maybe the MAS has to use the highest bitrate for a too long
sustained time? If so, there are two scenarios:
1) The MAS fails to encode the data, sending garbage to the CPU.
2) The CPU can't cope with the high data rate, and the MAS output buffer
is overflowed because the CPU doesn't fetch the data fast enough.
I wonder how we could test this...
