Configuring Google Hangouts for use with Devio

In most cases, you should be able to connect the Devio CR-1 to your computer, launch the soft codec of your choice, and the soft codec will automatically utilize Devio for all conference audio. However, it is sometimes necessary to manually configure a soft codec to use Devio, rather than its existing default audio device. This article will demonstrate how to configure this when needed.

Ensuring the computer recognizes Devio properly

When the Devio CR-1 is connected to a computer via USB, it will enumerate as a speakerphone. This means that it will provide both a microphone and loudspeaker to the computer.

If you wish to confirm that Devio has connected and enumerated properly, you can open the sound properties for the computer using one of the methods below:

Windows
  • Right-click on the speaker icon on the Start bar, then select Sounds

     
  • In the Sound dialog that will appear, check under both the Playback and Recording tabs

     
  • Confirm that the Devio CR-1 is listed in both of these places, and that it enumerates as a speakerphone
     
  • In each of these places, select the Devio CR-1 entry and click on "Set Default," then press OK to apply
     
  • If the Devio CR-1 does not appear properly, try the following:
    • Ensure that your USB drivers are up to date
    • Disconnect and reconnect the USB cable entering the computer from the Devio CR-1
    • Power cycle the Devio CR-1
    • Reboot the computer
Mac
  • Click on the Apple menu icon in the top-left of the display, then select System Preferences
     
     
  • Click on Sound

     
  • Under Output, the Devio CR-1 will enumerate as both an HDMI and USB Audio option. Be sure to select the USB option

     
  • Under Input, the Devio CR-1 will only enumerate as a single USB Audio option. Select this

     
  • If the Devio CR-1 does not appear properly, try the following:
    • Ensure that your USB drivers are up to date
    • Disconnect and reconnect the USB cable entering the computer from the Devio CR-1
    • Power cycle the Devio CR-1
    • Reboot the computer

Selecting Devio in Google Hangouts

  1. Click the gear icon at the top of Google Hangouts to access its Settings.

     
  2. Select "Echo Cancelling Speakerphone" for both the microphone and speaker options. This is how Devio will enumerate here.

     
  3. Click on Save to apply these changes.
     
  4. If audio does not appear to be passing to the far side, ensure that both your DTM-1's capacitive mute button and the mute button at the top of Google Hangouts are set to an unmuted state.
