修改STREAM_VOLUME_ALIAS_DEFAULT数组改成跟STREAM_VOLUME_ALIAS_TELEVISION数组内容一样所以音量条都属于music分组

    private final int[] STREAM_VOLUME_ALIAS_DEFAULT = new int[] {
        AudioSystem.STREAM_MUSIC,       // STREAM_VOICE_CALL
        AudioSystem.STREAM_MUSIC,       // STREAM_SYSTEM
        AudioSystem.STREAM_MUSIC,       // STREAM_RING
        AudioSystem.STREAM_MUSIC,       // STREAM_MUSIC
        AudioSystem.STREAM_MUSIC,       // STREAM_ALARM
        AudioSystem.STREAM_MUSIC,       // STREAM_NOTIFICATION
        AudioSystem.STREAM_MUSIC,       // STREAM_BLUETOOTH_SCO
        AudioSystem.STREAM_MUSIC,       // STREAM_SYSTEM_ENFORCED
        AudioSystem.STREAM_MUSIC,       // STREAM_DTMF
        AudioSystem.STREAM_MUSIC        // STREAM_TTS
    };
