\packages\apps\Camera\src\com\android\camera\SettingChecker.java文件中的setParameterValue()函数内:

 case ROW_SETTING_MUTE_RECORDING_SOUND:

           Log.i(TAG, "enableRecordingSound value = " + value);

            parameters.enableRecordingSound(value);

修改为

case ROW_SETTING_MUTE_RECORDING_SOUND:

           Log.i(TAG, "enableRecordingSound value = " + value);         

                   parameters.enableRecordingSound(1);
