Glad you're using a more powerful FPGA. I've spent far too much time struggling with various FPGA limitations. Whether size or speed related. If you're developing a cost sensitive design it may be worth jamming the logic in the cheapest possible FPGA but otherwise it's a particular corner of hell.
The AD7476 seems a strange choice for audio. There are loads of 16+ bit ADCs designed specifically for audio that will give optimum results with minimum effort. I've never had to design kit that needs an audio ADC so can't make any specific recommendations. If the AD7476 is already on the evaluation board then it will work for audio but 12 bits aren't really enough for high quality.
