先把packages/apps/Settings/src/com/android/settings/notification/NotificationSettings.java中如下部分注释掉。Setting把UI打开。
mSoundDevices = findPreference(KEY_SOUND_DEVICES);
161 /*paul change if(!"box".equals(SystemProperties.get("ro.target.product","tablet"))){
162 // getPreferenceScreen().removePreference(mSoundDevices);
163 // getPreferenceScreen().removePreference(soundmange);
164 // soundmange = null;
165 // mSoundDevices = null;
166 // Log.d(TAG,"remove SoundDevices======");
167 */ //paul change }
168 /*$_rbox_$_modify_$_zhangxueguang_$_end_$_20120409_$*/
169 }
将如下补丁打入hardware/rockchip/audio/tinyalsa_hal/audio_hw.c文件中。
