That's not actually the case, it's more flexible than that also...
-#define SYS_AUDIO_RATE 44100 -#define SYS_MCLK_RATE (SYS_AUDIO_RATE * 256) +#define SYS_AUDIO_RATE 48000 +#define SYS_MCLK_RATE (SYS_AUDIO_RATE * 512)
...if you're doing this you need to update the clock rates supplied to the CODECs otherwise they won't be able to generate the required audio rate.
