* SOUND_x enum can be generated by audiohw_settings.h along with settings entries and sound_val2phys. * VOLUME_MIN and VOLUME_MAX are no longer necessary within sound.c. If you need them, they are for target-defined purposes. * Fix up SDL volume implementation in sdl.c. Move sim volume calculation code to pcm-sdl.c. * Min trigger tresholds were based upon VOLUME_MIN for some reason. These setting have nothing to do with playback volume. Since it is no longer present, set these at -89dB which is the minimum peak meter sensitivity setting. * Fix an oversight in wm8758.c. I forgot to add the dB->register conversion to audiohw_set_volume. Change-Id: Ie1df33f1793eee75e6793f16bc7bddd16edb7f75
