Peter,

You are going to have problems emptying the UART FIFO's fast enough on 
your target hardware at a baud rate fast enough to transfer audio I know 
I have seen these issues before.
You would be better using another medium for the transport USB or SPI or 
something other than a UART.

Regards.
