TrueConf for Windows enables you to share audio content during video conferences, e.g. YouTube videos or browser windows. In this case, you won’t need to interrupt communication with other users. We are going to show you how to take advantage of this feature by connecting a virtual microphone to the TrueConf application (using VB-Audio Software as an example). It is worth noting that users will hear sounds from all the applications launched by the speaker when a virtual microphone is on.

How to Connect a Virtual Microphone

Step 1: Install VB-Audio Software

  1. Download an archived driver package from the VB-Audio official website and unzip files.
  2. Select a distribution kit depending on the bitness of your operating system and install it as administrator.
  3. Restart your computer.

Step 2: Set up a VB-Audio virtual microphone

  1. Go to Start Menu → Settings → System → Sound → Sound Control Panel (Related Settings section).
  2. On the Playback tab, select CABLE Input and click the Default button. This will allow you and other users to listen to broadcast content.sound-settings-en
  3. On the Recording tab, click Properties in the context menu of the CABLE Output item.
  4. In the window that opens, use the Listen tab:
    • To check the Listen to this device box.
    • Select your playback device in the list below.

We are done with virtual microphone setup. It will now be displayed as a recording device in your TrueConf client application.

How to Share Audio Content During a Conference

Option 1: Switch from conference communication to content sharing

During a video conference, switch to content sharing in the TrueConf application. Next, use the application toolbar to select the above CABLE Output (VB-Audio Virtual Cable) virtual microphone as a recording device. Other conference participants won’t hear your voice but sound from the content you are sharing.cable-output-en

To let the rest of conference participants hear you while sharing content, use the application toolbar to switch to your main microphone.

Option 2: Share content and communicate simultaneously

You will need to launch your application instance and log in using an additional account. This instance will be used to share audio content during a conference. You will keep communicating with other users in the application where you are logged in to your account.

Step 1: Getting started with audio content sharing

  1. Once you have launched the TrueConf application and the instance, log in to them:
    • Copy the shortcut of TrueConf for Windows and give it a name, e.g. TrueConf 2
    • Select the Properties tab in the context menu of the shortcut
    • Add the -t switch to the Object field after the quotation marks limiting the file name (note that there must be a space before -t). As a result, the line will look like that:
  2. Join the conference in both application instances.
  3. In the application window which will be used to share audio content, use the toolbar to select CABLE Output (VB-Audio Virtual Cable) as a recording device. In the Video and Playback Device sections, select Do not use.
  4. In the application window which will be used to communicate during a conference, use the toolbar to switch to your microphone.

Step 2: Participate in a conference

When necessary, start sharing content in the second application. It will be seen and heard by all conference participants.content-share-en
