Try to (re-)implement AFC sound. This is an adaptation of the code I commented out in the PCM16 commit.
For some reason AFC sound is slightly wrong. I don't know if it also happened before, but I'll work on it. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@3600 8ced0084-cf51-0410-be5f-012b33b47a6e
