Working with built in speaker and mic on dm365x evm

enable audio drivers in your kernel config. Also make sure Input connections are valid. I think there is a inbuilt mic on most of the EVM's , if not you can use external mike as well.

If I get it right, driver for codec CQ93VC which is used by inbuilt mic and speaker, is only in newest version of PSP. But I can't compile DVSDK modules for it's kernel. This codec might be useful because it's already on chip. Here is some info about  senchuss attempts to make it work but if I didn't miss something, he wasn't happy with the result.
