Multimedia

Audio

You can speak and listen through the device audio or the USB headset. You can also use buttons on the USB headset (such as mute and skip). The user experience is enriched by providing smooth audio output.

You can’t play an audio file within a session on Safari macOS.

Plug and play audio device support

We support multiple audio devices and redirect them to the virtual desktop session. Now, when you redirect audio devices, you can view the audio device name under the Sound settings > Playback and Sound settings > Recording on the virtual desktop session. The list of devices on the VDA is dynamically updated whenever an audio device is plugged in or removed.

Known limitations

• On the VDA, the name of the built-in audio device is in English only. The issue occurs when you use ChromeOS-based devices. [RFHTMCRM-8667]
• This feature is supported on Microsoft Chromium Edge and Google Chrome browsers only.

Webcam

Citrix Workspace app supports webcam redirection for both 32-bit and 64-bit applications, built-in, and external webcams within the virtual desktop and app sessions. The Workspace app detects newly connected external webcams and makes them available for use dynamically.

Webcam redirection support is available not just for Google Chrome and Microsoft Edge (Chromium) browsers, but it has also been expanded to include Mozilla Firefox and Apple Safari browsers.

Microsoft Teams optimization

You can now use the following features of Microsoft Teams for virtual desktop and virtual app sessions on the Google Chrome browser only. The minimum Google Chrome version required is m97 and later:

• Optimized audio calls

• Optimized video calls

• Optimized screen sharing

• Support for e911

• Background blurring effects

• Dual Tone Multi Frequency (DTMF)

• Live captions

Note:

• The Microsoft Teams optimization applies to the Microsoft Teams desktop version and not the web version on the VDA.

Feature limitation:

• When you use Microsoft Teams optimization and share the screen, a red border that indicates the screen sharing is unavailable. [RFHTMCRM-6360]
• When you use Microsoft Teams optimization, the screen sharing functionality is disabled by default. After you enable it, you can share the local device contents. [RFHTMCRM-6156]

Known issues in the feature:

• Microsoft Teams optimization is supported on the Google Chrome browser only. [RFHTMCRM-6194] [RFHTMCRM-4724]

Screen sharing

Starting with version 2209, by default, the screen sharing is enabled. The end users can now share apps and tabs that are opened through Citrix Workspace app. During screen sharing, the blue border appears around the shared window.

Support for dynamic e911

Citrix Workspace app supports dynamic emergency calling. When used in Microsoft Calling Plans, Operator Connect, and Direct Routing, it provides the capability to:

• configure and route emergency calls
• notify security personnel

The notification is provided based on the current location of the Citrix Workspace app that runs on the endpoint, instead of the Microsoft Teams client that runs on the VDA.

Ray Baum’s law requires the 911 caller’s dispatchable location to be transmitted to the appropriate Public Safety Answering Point (PSAP). Starting from Citrix Workspace app 2202 for HTML5, Microsoft Teams Optimization with HDX is compliant with Ray Baum’s law.

For Microsoft Teams optimization e911 calling, enable Location access as shown:

Background blurring and effects in Microsoft Teams optimization

Starting with the 2303 release, Citrix Workspace app for HTML5 supports background blurring and effects in Microsoft Teams optimization for video calls. You can either blur or replace the background effects provided by Microsoft Teams to avoid unexpected distractions by helping the conversation stay focused on the silhouette (body and face). This feature can be used with P2P and conference calls. This feature is integrated with the Microsoft Teams UI.

Notes:

• By default, this feature is disabled. To get this feature enabled, contact your organization’s administrator for assistance.
• Multi-window support is a prerequisite that requires a VDA update to 2112 or higher. For more information, see Multi-window meetings and chat.

Limitations

• Administrator and user-defined background replacement aren’t supported.
• When you enable this feature, you might observe performance issues.
• After the ICA session is reconnected, the effect is off. However, the Microsoft Teams UI shows that the previous effect is still On by a tick mark. Citrix and Microsoft are working together to resolve this issue.

Multi‑window chat and meetings for Microsoft Teams

Starting with the 2301 version, you can use multiple windows for chat and meetings in Microsoft Teams. You can pop out the conversations or meetings in various ways.

For details about the pop‑out window feature, see Pop out a chat in Microsoft Teams. For troubleshooting see, CTX253754.

Microsoft will deprecate the single‑window support in the future. If you’re running an older version of Citrix Workspace app or Virtual Delivery Agent (VDA), you can upgrade to:

• Citrix Workspace app 2301 or later and
• VDA - 2203 or later

Live Captions in Microsoft Teams

Microsoft Teams optimization supports real‑time transcription of what the speaker is saying when Live Captions is enabled in Microsoft Teams.
