Probably in your system, yes. The most important thing from an audio
performance point of view is that the clocks are all derived from the
same clock source - if this is like other Atmel systems then you need to
make the CODEC clock master on the audio bus as the MCLK output from the
CPU is not synchronous with the audio clocks.
