Dell ThinOS 2211, 2208, and 2205 Administrator’s Guide

From ThinOS 2211 and Citrix Workspace App 2209, App sharing is enabled in Microsoft Teams optimization mode. You can share an application using the Screen sharing feature in Microsoft Teams. The feature is applicable on Citrix Virtual Apps and Desktops 2109 and later.

ThinOS supports audio optimization for Microsoft Teams using Citrix Workspace app 2101.

To enable the Teams optimization feature for Citrix, you must meet the following requirements:

• Install the Microsoft Teams on your VDI desktop. For more information about the Microsoft Teams installation, see the Optimization for Microsoft Teams article at docs.citrix.com.
• Review the system requirements of Citrix Virtual Desktops and VDA. For more information about the system requirements, see the Optimization for Microsoft Teams article at docs.citrix.com.
• Enable the Microsoft Teams redirection policy is enabled in Citrix Studio. For more information about how to enable the Microsoft Teams redirection, see the Multimedia policy settings article at docs.citrix.com.

On the ThinOS client side, you must download the Citrix package from Dell.com/support and install the package using Admin Policy Tool or Wyse Management Suite. For information about how to install the ThinOS application packages, see the Upload and install ThinOS 9.x application packages using Admin Policy Tool or Upload and install ThinOS 9.x application packages using Wyse Management Suite.

To verify if the Microsoft Teams application works in the optimized mode, click About > Version to view the Citrix HDX Optimized legend. For more information about how to verify the Microsoft Teams audio optimization, see the Optimization for Microsoft Teams article at docs.citrix.com.

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 occasionally on a thin client with dual core CPU.
• Other known issues for CWA Teams Optimization
  • If the Use video codec for compression Citrix policy is set as For the entire screen, app sharing is not available. You can use other video codecs instead. The issue also occurs in Linux Citrix Workspace app binary
  • 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.
  • 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.
  • The integrated audio speakers on Wyse 5470 thin clients emit an echo during calls or meeting.
  • If there is a Microsoft Teams call or meeting happening between a Wyse 5470 thin client and a thin client that is or is not Wyse 5470 thin client, you may encounter audio issues when you enable the camera or share your screen. As a workaround, do not enable camera during calls or meetings, and the host with Wyse 5470 client must not move applications quickly in ICA sessions.
