Audio Support

Stereo audio output and mono audio input are supported and enabled by default.

The PCoIP Client provides an enhanced audio and video synchronization (AV Lock) feature that provides improved full-screen video playback, reducing the difference in delays between the audio and video channels and smoothing frame playback on the client. This improves lip sync and reduces video frame drops for movie playback. This feature introduces a small lag in user interaction responsiveness when enabled. Using enhanced audio and video synchronization will reduce the maximum frame rate.

Audio input devices should not be bridged to the remote session. Audio input devices are locally terminated and utilize local OS audio drivers. A bluetooth headset can be supported locally, but cannot be bridged.

Note: Special configuration required for macOS 10.15 (Catalina)

Special configuration is required to enable microphone access on macOS 10.15. For instructions, see Microphone Access on MacOS Catalina 10.15.

Multi-Channel Audio Output

The PCoIP Client supports multi-channel audio output when connecting to the macOS PCoIP Graphics Agent.


  • A multi-channel audio device that supports 2.1, 5.1 or 7.1 channel configuration.
  • PCoIP Graphics Agent for macOS version 21.10 or newer.
  • PCoIP Client for macOS version 21.10 or newer.
  • PCoIP Standard Agent for Windows version 22.04 or newer.
  • PCoIP Graphics Agent for Windows version 22.04 or newer.

Current Limitations

  • Only 2.0, 2.1, 5.1 and 7.1 channel configurations are currently supported.

Enabling Multi-Channel Audio Output

After you connect your audio device to your macOS PCoIP Client, follow the instructions outlined below to ensure it is configured as the default audio device prior to establishing your PCoIP session:

  1. From the macOS System Preferences click Sound. Alt Text
  2. Click on the Output tab.
  3. Select the audio device you wish to make your default device.
  4. Close System Preferences.

Once you have set the default audio device you can connect to your PCoIP Agent for macOS. During session negotiation the PCoIP Agent will configure PCoIP Virtual Speakers, with the same number of channels as your PCoIP Clients default audio device.
