STM32F107 I2S with CubeMX

Hi, I'm trying to use I2S2 in STM32F107VC in this Configuration:

 

SYSCLK and HLCK: 72 MHz

I2S2 Clock (Using PLL3_VCO): 80 MHz

 

But in configuration tab I can't set audio frequency more than 32 KHz (i.e. 44 KHz 48 KHz and 96 KHz).

The CubeMX error is:

"With this I2S Clock (36.0 MHz), the divider value 1 is too low to obtain the desired Audio Frequency (44.0 KHz).

The I2S Clock must be higher than (45.056 MHz)."

 

Is it possible to implement higher audio frequencies?

Any guidance could be helpful.

Thanks
