Significant delay in audio when performing VC from RDP

When using RDP from Windows to Windows, and starting a VC call (for example, in MS Teams), the audio becomes delayed with regard to the video. This delay can reach 10 seconds.

The same scenario happened when using xfreerdp client and performed RDP from Linux to Windows.

When I stopped the network connection on the RDP client and resumed it, the VC session resumed at the point it stopped - it seemed like some kind of audio buffer was saved on the remote Windows server during the call.

I want to know:

  1. Is there any control over the saved audio buffer? Why do the video and audio behave differently?
  2. What can be any other solution to the problem?
  3. Is using VC on RDP recommended at all? If not, what is the recommended way?

    Welcome to the Microsoft Q&A Platform and thank you for your question!

    Based on your description, allow me to provide you some recommendations to address audio delays when performing video conferences from an Azure Virtual Desktop (AVD) session.

    1. Enable Multimedia Redirection

    • Configure your AVD session hosts to support multimedia redirection.
    • Use the browser extension or apply Group Policies to enable redirection for specific domains or all sites.

    2.Update Software and Drivers

    • Install the latest Microsoft Visual C++ Redistributables.
    • Ensure the RDP client and Teams app are updated to the versions that support Teams media optimization.

    3.Use Wired Connections

    • Even small Wi-Fi packet loss (~1%) can cause robotic or delayed audio. A wired network provides much better stability.

    4.Check Permissions and Device Settings

    • On the host, verify microphone and speaker permissions under Windows Settings > Privacy & Security.

    5.Avoid Bluetooth Headsets

    • Bluetooth introduces additional latency. For best call quality, use a wired headset.

    Please let me know how it goes. Wishing you a successful resolution and a great day!
