				#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：
