Please take a look at:
http://www.wolfsonmicro.com/products/WM8994
for an example of a modern smartphone CODEC. This has in the ballpark
of 75-100 nodes (I've not counted exactly) represented in the routing
graph in the driver today. This does not include any audio routing
available in other components such as the CPU.
