Microsoft Teams optimization limitations
● Video call and share screen features are not supported on Wyse 3040 Thin Clients due to client resource limitations.
● Video call and share screen features are recommended on Wyse 5070 Thin Clients, 5470 Thin Clients, and Wyse 5470
All-in-One Thin Clients with known issues.
○ The audio gets distorted during a meeting when you share screen from thin client to a laptop or desktop that uses native
Microsoft Teams. There is no workaround right now and the issue is being worked on.
○ The audio gets distorted during a meeting when all the participants mute while the screen presenter is sharing the
screen or the camera, with audio. Workaround is to ensure that at least one participant has not muted while the screen
presenter is sharing screen or has the camera enabled.
○ When users share screen in a Teams meeting between Wyse 5070 thin clients or Wyse 5470 thin clients, the audio gets
distorted while talking.
○ The audio gets distorted when you play HTML5 videos using Browser Content Redirection in the shared screen when in a
meeting.
○ The audio gets distorted when you browse a website with multiple pictures in the browser while sharing screen.
○ The audio gets distorted occasionally on a thin client with dual core CPU.
● Other known issues for CWA Teams Optimization
○ Depending on your network bandwidth latency, the audio quality may fluctuate. To avoid this issue, ensure that your
network bandwidth is adequate for audio or video call. Citrix recommends 200 kbps or higher network speed for a single
client.
○ Switching cameras during a Microsoft Teams call in not recommended. This issue is a known Citrix Workspace App
limitation [Case #80109986].
○ Session termination or abrupt disconnect may result in unexpected HdxRtcEngine.exe processing exits. This issue is a
known Citrix Workspace App limitation [RFLNX-5885].
○ Audio is still played through the first headset when you switch to the second headset during the call. This issue is
observed when you have installed the JVDI package on the thin client. Workaround is that if you are using Microsoft
Teams (or Zoom), do not install the Cisco JVDI package. This issue is due to Cisco limitation.
○ When using a headset, you cannot answer or end the call through headset buttons. This issue is due to a limitation of
Microsoft Teams.
