STM32F4 I2S setup registers

Hi all. I'm currently attempting to get the audio codec on the STM32F4 disco board working as I want to create a simple i2s codec library that will work with the Arduino/Libmaple port from Roger Clark (STM32Duino) I am not using th standard periph libraries but have the libmaple API which has most of the register definitions and atomics.

So far I have been able to get SPI3 working remapped to pins C10(sck) and C12(mosi) and have got I2C working on pins B6 and B9.

My problem is getting MCLK configured. I have the C7 pin configured in AF mode as output PP but am having difficulty actually enabling the clock. 
I would like to know if anyone has attempted to configure I2S using just registers or without the STD periph libraries with any success...
