如何在声音菜单中加入麦克风调整

当我使用 Skype 时，我有 2 个用于声音的滚动条：

在此处输入图片描述

我怎样才能始终保留这 2 个滚动条，而不仅仅是在进行 Skype 对话时？当我不与 Skype 对话时，只有扬声器滚动条可见。

以下是输出sudo updatedb; locate -r indicator-sound-service$：

  1. 下载构建依赖项和源代码

    sudo apt-get build-dep indicator-sound
apt-get source indicator-sound

  2. 改变src/volume-control.vala

    修改默认从false为true：

    /** true when a microphone is active **/
public bool active_mic { get; private set; default = true; }

    使用以下方式设置隐藏变量的注释行//：

                case Context.SubscriptionEventType.REMOVE:
                //this.active_mic = false;
                break;

  3. 构建和安装

    cd indicator-sound-12.10.2+14.04.20140313/
mkdir build
cd build/
cmake ..
make
sudo make install

  4. 终止正在运行indicator-sound-service或注销/登录

    pkill -f indicator-sound-service

显示麦克风始终处于声音指示器弹出状态

笔记：

由于某些原因，您可能想要跳过sudo make install或不起作用，然后只需替换可执行文件：

sudo rm /usr/lib/x86_64-linux-gnu/indicator-sound/indicator-sound-service
sudo cp src/indicator-sound-service /usr/lib/x86_64-linux-gnu/indicator-sound/indicator-sound-service
pkill -f indicator-sound-service
