Citrix workspace 2104. Dell Wyse ThinOS Version 9.1.3129, 9.1.3112, 9.1.2101, and 9.1.1131 Operating System Release Notes

 

Update history for Microsoft Teams App Version here. Citrix strongly recommends the latest current release Workspace app version.

Most of the new features require an upgrade of the Workspace app, hence the Current Release model is the preferred delivery mechanism.

Also, keep in mind that Teams feature set is different when comparing optimized vs non-optimized. When Teams is not optimized, it runs on the VDA with its native media engine and all the features are supported although multimedia rendering happens on the VDA, incurring in a CPU tax. Step-by-step: Microsoft Teams optimization mechanisms can be divided into 5 main areas. Proper troubleshooting requires the Admin to verify each area progressively, moving down the list.

Please note that the presence of a Citrix Gateway as an HDX proxy should have no impact, so you can discard that from your troubleshooting. If you are also using the Gateway for VPN, make sure you are allowing the client machine to reach the O Teams servers. This means Teams is ready for an optimized call. Teams will read this key when starting, and if the value is 1, it will load in VDI mode.

The value is set to 1 automatically if and only if:. Sometimes, if Teams auto-updated while the session was in disconnected state, it can fail to read the key properly upon reconnections. Common issues could be erroneous cached items settings. Customers are advised to contact Microsoft support in this case. In other words, Teams must open a secure websocket connection to this service, which listens at If WebSocketService.

Otherwise, redirection will fail. You must "bypass proxy servers for local address" If not, optimization will fail. One way to do this:. Ensure you apply the proper exclusions for the WebScoketService. Relaunching Teams might be required. Also, in some rare cases, you might see WebSocketAgent. Action : If WebSocketAgent. If HdxRtcEngine. Each HDX session will create its own separate folder.

All the peripherals should now be mapped, and the video self-preview visible. You should be able to toggle between the cameras too.

The "Make a test call" button is a very handy tool to assess peripheral acquisition and performance. Open mmsys. These are the ones that will be auto-selected by Teams. You can toggle these devices in the middle of a call - in that case, a 1 sec audio glitch might be experienced while the new devices are remapped.

The peripheral acquisition process is captured in the webrpc. As a workaround, open the Sound Control Panel mmsys. Also, "Restore Defaults" under Advanced can be used to recover from this error. Alternatively, disable the specific device. Important note for branch-office proxies : HdxRtcEngine. This was fixed in:. In those releases, the HDX media engine will read the system proxy settings and honor the configuration e.

In case of a peer-to-peer connection or conference via UDP, then Wireshark will show more detailed info that can be used to understand the traffic flow between the participants.

Wireshark recommendations: RTP cannot be automatically analyzed by Wireshark. After the connection is established, there will be UDP traffic sent regularly between the peers. Media Engine multimedia stream processing Once the call set up is finalized and the ICE connectivity checks are completed, the media will be exchanged between the parties.

Currently we support video resolutions up to p 30fps, with p being common [H and VP9]. DxVideoRenderer Info: configure. CameraCapture Info: start. The encoding process camera capture and subsequent encoding is more expensive in CPU terms than decoding.

The RTP protocol can be decoded in Wireshark to understand what type of codecs are being used and how much bandwidth is consumed. The calling party will state all his supported codecs, and the callee will then reply with his preferred choice in the SDP answer.

Apply the proper filters to display only the traffic associated with the call. In other words, there was no offloading of such streams and therefore they were rendered server-side natively by Skype for Business. But in terms of HDX optimization for Microsoft Teams, incoming screensharing is no different than incoming webcam video streams, since Teams relies on video-based-screen-sharing.

Hence it is optimized by default. However, a VDI user sharing his monitor i. Currently it is only possible to share the primary default monitor with CWA or older. If Desktop Viewer cdviewer. In multi-monitor setups, only the primary monitor is shared, and the screen picker button in Teams will label the preview as 'Screen 1'.

Troubleshooting screensharing issues: Common issues with screensharing, as perceived by the other peer, are: - low resolution or low fps - black window instead of the actual screen - screen freeze from the sender's side The webrpc. So screensharing might actually start with a low resolution before it jumps to a higher one.

In the webrpc logs, look for "webrtcapi. VideoTrackSource Info: setOptions" to spot what resolution and fps is being applied:. In the logs, also the parameter "w ebrtcapi. DesktopCapture " can be used for quick finds, and if there are errors they would be logged as " webrtcapi.

DesktopCapture Error: ". Black windows can be caused by issues on the sender's side user capturing or the receiver's side user rendering the stream. For example, if the error is on the sender's side the following entry could be seen: webrtcapi. Please see below for the detailed field description:.

Please contact your device manufacturer to download the latest version of the driver. Image effects will be delivered in a subsequent Linux release. Endpoints using this driver can experience call freezes or disconnections in meetings or calls.

This version will support Background Blurring and Effects once Microsoft rolls out a feature flag check for updates here. Calling is not available yet". See CTX No VDA dependency. No VDA or Teams versions dependency. The feature is controlled via client-side regkeys.

CWA for Windows Thanks to this feature, users can share their webcam and screen at the same time. In the past, the webcam would have been disabled the moment a user also started to screenshare.

CWA Issue is fixed in VDA or higher. Any version equal or lower will not be able to run new features for VDI. Public Microsoft Teams roadmap is available here. These releases include improvements in conference call performance, but the availability of this feature depends on an upcoming Teams update.

Check edocs for further details. Microsoft working on a fix Microsoft case ref. See here. As a result, incoming calls are not displayed in Microsoft Teams toaster called party does not receive any notifications. The latter is a 7x7 layout i. Citrix recommends you enroll. This is caused by a delay in the Teams UI refresh.

If Teams is configured to Auto-start, the issue in the bullet above might also manifest. Deleting the regkey described in the bullet above should fix this.
