A780手机内置及外放音量小的问题,一直困扰众多的用户。780的音量大小其根本上是由系统内部的参数控制,由于授权的要求,不是一般用户所能更改的。本人经过在不同版本的多次测试,用以下方法更改,效果非常显著。
1、手机必须支持mpkg格式软件的安装及自启动(关于如何支持及自启动,机油可参考其它相关教程)。
2、在手机中安装高级文件管理器并打开,找到手机的根目录,依次打开tmp/xiaofei06/文件夹,复制GainTable.txt文本文件到TF卡中的任意目录(自己可以找到)。
3、建议在电脑中进行操作,因为GainTable.txt文本文件在手机中打开后,其中的数据参数较多,容易出错。在电脑中安装UltraEdit-32软件,打开从手机中复制到电脑的GainTable.txt文本文件进行参数修改后保存。本人修改后的完整参数是这样的:

机油也可以自行修改参数,需要注意的是:建议只修改每行数字中的最后,最大不要超过80,否则会有破音了。
4、把修改后的GainTable.txt文本文件传入到手机中的任意目录(自己可以找到),打开手机中的高级文件管理器,找到GainTable.txt文本文件,复制到手机系统目录下的ezxlocal/download/appwrite/setup文件夹内。
5、在手机预置文件夹或TF卡的根目录下建立自启动文件startup.txt,加入如下代码(如果手机中已有自启动文件,就在其中加入):mount --bind/ezxlocal/download/appwrite/setup/GainTable.txt/tmp/xiaofei06/GainTable.txt
kill $(pidof soundmanager)
sleep 3
6、关机重启。
