1、关于 AUDIO DAC 和 MUTE 部分的修改方法：1， 在 8032 目录下的 MAKEFILE 文件中有如下定义：!ifndef ADAC_DEF!if (defined(DO_1379) | defined(DO_SIMP79) | defined(DO_NUI) | defined(DO_NUI_S) | defined(DO_NUI_B)ADAC_DEF = _CS4360_ /定义 AUDIODAC 类型，内置时此处定义 _NPADAC_!else # 1369ADAC_DEF = _AV2188_!endif # 13692， 在 VENDOR。H 中关于 AUDIO DAC
2、 定义处：/#define AC3_DITHER_MUTE/#define AC3_BASS_OVERFLOW_DETECT/#define DAC_AUTO_MUTE/#define DAC_DEEMPH/#define DAC_EXTPIN_MUTE#ifdef MT1389_REV_E /89E 内置 51CH 的 DAC#define MTK_6CH_ADAC#define DSP_AUTO_MUTE /mask it temperally, open it until dsp complete auto mute function.#undef _WM8756_/#define MT
