When using Cam Link to capture video as well as audio, there may be no audio captured. To fix this, there are two methods:

Capture HDMI audio from Cam Link - Method #1
  1. Open the properties of Cam Link source (Right click -> Properties)
  2. Check the box title Use Custom Audio Device
  3. From the Audio Device dropdown menu, choose Digital Audio Interface (Cam Link)
Capture HDMI audio from Cam Link using Audio Input Capture source - Method #2
  1. Add a new Audio Input Capture source to a scene
  2. From the Device dropdown menu, choose Digital Audio Interface (Cam Link)
  3. Click on ok.

Does Cam Link support multiple devices connected at the same times?
  • Yes.
Issues when more than one Cam Link are being used
  • If using multiple Cam Links is causing issues, make sure they're on separate USB port controllers. Cam Link uses about 2Gbps of bandwidth (Uncompressed 1080p60 video) and two Cam Links may be overloading the USB controller.
Fix stuttering audio/video from Cam Link

Changing USB transfer mode:
  • Cam Link by default comes in the bulk USB transfer mode. This mode of transferring audio/video over USB is more compatible with Windows systems, but may cause issues on macOS systems. To fix this, the transfer mode needs to be changed. This happens automatically when a Cam Link is connected to a system and the Game Capture software is launched.
  • Windows - Bulk mode
    • Connect Cam Link to a USB 3.0 port on your computer
    • Run the Elgato Game Capture software
    • Wait 10 seconds
    • Close the Elgato Game Capture software
    • Cam Link is now running in Bulk mode
  • macOS - Isochronus mode
    • Connect the Cam Link to a USB 3.0 port on your mac
    • Run the Elgato Game Capture software
    • Wait 10 seconds
    • Close the Elgato Game Capture software
    • Cam Link is now running in Isochronus mode.
If that does not fix the stuttering, make sure Cam Link is connected to a USB 3.0 port with no other device connected to the port next to it. This other device may be using too much bandwidth for the USB controller to handle.
