From 0c7b7873984e04941c9f21fa272638018fdb9a16 Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Fri, 12 Apr 2013 23:35:47 -0400 Subject: Straighten out the mad twisted state of sound.c and related areas. This is going right in since it's long overdue. If anything is goofed, drop me a line or just tweak it yourself if you know what's wrong. :-) Make HW/SW codec interface more uniform when emulating HW functionality on SWCODEC for functions such as "audiohw_set_pitch". The firmware-to- DSP plumbing is in firmware/drivers/audiohw-swcodec.c. "sound_XXX" APIs are all in sound.c with none in DSP code any longer. Reduce number of settings definitions needed by each codec by providing defaults for common ones like balance, channels and SW tone controls. Remove need for separate SIM code and tables and add virtual codec header for hosted targets.
