WVD and teams optimization

We have deployed a WVD pool with teams using the optimization for WVD. The camera and mic are working fine but we have a real big problem with audio and video quality. It would seem to be worse when in group calls. The issues we are facing is delayed voice and pixelated video.

Has anybody else experienced issues like these?

Are the any other tweaks that can be made to improve the quality?

    Will be testing a new PoC this week and will also check how Teams is doing with the things u mentioned.

    This is also a major issue for us. I have a ticket open, but is going nowhere fast.

     

    WVD with FSLogix profiles (and the correct exception) and WebRTC Optimisations enabled.

     

    *Audio begins in sync. But as a meeting goes along, the video gets more and more out of sync compared with the audio. A terrible experience, and affects everyone using WVD. In some instances I have seen over 5-10 seconds delay.

    *Video quality can be very poor and pixelated, but is perfect on a local machine. Movement causes this to become worse.

    *Audio quality is generally fine

    *A large delay in switching video streams as gallery mode does not work in WVD

    *1 to 1 calls seem to be better, larger meetings are much worse.

      Yes it's poor and totally useless. I also have a open case with MS but that is painfull at the momment asking stupid questions.

       

      I will let you know how we get on but it's good to know somebody else has the same issue as us.

        What vm size are you using? Just a thought but maybe try provisioning a larger size vm on its own as a test using Teams and see how that behaves?

    Sorry this reply is so late. But i recently encountered this issue as well. One change we made that improved performance was to disable RSC on the network adapter.

     

    1. Open a powershell admin prompt

    2. Run cmdlet >   Get-NetAdapterRSC

         a.) Your going to look for the name of the primary network adapter in use by the WVD.

    3. Run cmdlet >    Disable-NetAdapterRSC -Name "NAME OF ETHERNET ADAPTER"

     

    Once we turned off RSC on our WVD pool template, users noticed better performance on teams. Turn off RSC has not degraded or caused any issues for the end users experience on other applications.

      That one was new.
      Really good input to this conversation! This one was new to me. I will evaluate it at my customers. If this changes the performance, I will have lots of happy users.

        Small update on our ticket running ms Support : They announce us a new WEB RTC Redirector version by end of June that should fix our audio/voices issues in Teams inside WVD.
