我是靠谱客的博主漂亮小蚂蚁，最近开发中收集的这篇文章主要介绍9. 音频调试日志，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1. 音频参数(客制化共8个文件)
	audio_acf_default.h					-- 不用改
	audio_custom.h						-- 不用改
	audio_hcf_default.h					-- 不用改
	audio_music_drc_default.h			-- 要改
	audio_ringtone_drc_default.h		-- 要改
	audio_ver1_volume_custom_default.h	-- 要改
	audio_voip_custom.h					-- 不用改
	audio_volume_custom_default.h		-- 不用改
	sph_coeff_default.h					-- 不用改 - 降噪后面会专门提出优化

2. 查看音频模式 - 根据功放芯片手册
	01						模式1	speaker mode	- 功率0.6w
	0101					模式2	speaker mode	- 功率0.85w
	0101 0101 0101			模式6	speaker mode	
	0101 0101 0101 01		模式7
	0101 0101 0101 0101		模式8


	Z:kernel-3.18soundsocmediatekmt_soc_audio_v3mt_soc_codec_63xx.c
	
		static void Ext_Speaker_Amp_Change(bool enable)
		{
			if (enable) {
				#if defined(CONFIG_KST_BOARD_V618)		// 0101 为模式2	- 功率0.85w
					mt_audgpio_set_gpio(0);
					mt_audgpio_set_gpio(1);
					mt_audgpio_set_gpio(0);
					mt_audgpio_set_gpio(1);
				#else
					mt_audgpio_set_gpio(1);				// 1   为模式1	- 功率0.6w
				#endif
				
				

3. 调试：
	1.喇叭没有声音----硬件测喇叭是好的
		1.1硬件原理图查看喇叭gpio口
			\192.168.22.243software_HW_Resource_项目分类b939-37原理图B939_MB_V5.0_20161125.sch
			查看得知为GPIO2
		
		1.2修改驱动
			kernel-3.18soundsocmediatekmt_soc_audio_v3mt_soc_codec_63xx.c
			1867  #define GPIO_SPEAKER_EN_PIN	2		//改为2
	

案例一：	mt6739平台音频参数客制化

硬件工程师调试出来的mt6739平台音频参数是一个default.audio_param文件，和之前的mt6580、mt6737等平台的不一样，在mtkonline上搜索default.audio_param关键字，查到如下faq：
[FAQ17569] [AudioTuningTool]如何集成Audio_Tuning_ToolV2.2(或以上)版本的音频参数
其中有说明只要将default.audio_param放在$(MTK_TARGET_PROJECT_FOLDER)/目录下或device/mediatek/$(CHIP)/目录下即可，该规则是在alps/vendor/mediatek/proprietary/external/AudioParamParser/DeployAudioParam.mk中定义的。
解决办法：只要如下修改代码即可客制化mt6739平台的音频参数：
