Known issues

• When working with a Philips SpeechMike or Nuance PowerMic 4 device, the screen saver might not be displayed after the configured period of inactivity when recording is in standby mode. To disable this behavior, press-and-hold the left mouse and touchpad buttons on the recording device for five seconds. When the firmware setting has been changed successfully, the device provides visual and audio feedback. This setting is stored on the device and needs to be changed individually on each device. [CAVE-6152]

• Connecting two different control devices at the same time is not supported. Button presses might not map to the expected actions. [CAVE-6093]

Important information

• Starting with Citrix Virtual Apps and Desktops 2109, the 'Virtual channel allow list' policy setting will be enabled by default. This means that custom/third-party virtual channels will no longer work with the default configuration.

The following options are available:

Disable the 'Virtual channel allow list' policy setting to allow all virtual channels again.

Add the Nuance virtual channels to the allow list; for more information, see the Citrix documentation.

For more information, see the Nuance Citrix Extension Deployment and Configuration Guide delivered with the Nuance virtual extension package or contact Nuance Technical Support.

• Be aware that your application must be recompiled following this upgrade.

System requirements - all clients*

Remarks

• Dragon Medical SpeechKit only supports Internet Explorer 10 on platforms for which Internet Explorer 11 is not made available by Microsoft.

System requirements - virtualized environments*

Supported microphones

Audio works for all microphones listed. Support for button controls is listed below:

* To enable Nuance PowerMic controls, install the Nuance PowerMic Citrix Extension/PowerMic RDS Extension/PowerMic VMware Client Extension.

** To enable button controls for third-party devices, install the corresponding redistributable packages.

*** To enable button controls for these devices, configure USB device splitting.

Remarks

• For more information on virtualized environments, see the Docs & Guidelines folder of the Nuance virtual extensions package on the Nuance Healthcare Development Platform.
• For security reasons, make sure that VDI channel encryption is enabled between client end points and VDI servers or virtual desktops. Disabling encryption in a virtualized environment can lead to PHI being exposed. Encryption is enabled by default.
• Nuance Citrix/RDS/VMware Audio Extension and Nuance PowerMic Citrix/RDS/VMware Extension:

The extensions do not need to be installed on the server/virtual desktop; the required server binaries are already included in the application folder.

Make sure you uninstall the corresponding server/virtual desktop component setup if it is no longer used by other products.

• Nuance RDS Audio Extension and Nuance PowerMic RDS Client Extension: UDP transport must be disabled on Remote Desktop Protocol (RDP) clients.

To disable UDP transport, add the following registry keys and value to the Remote Desktop Client, then restart the PC:

Keys:

HKEY_LOCAL_MACHINE\Software\Microsoft\Terminal Server Client

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Terminal Server Client

DWORD Value:

DisableUDPTransport = 1

• VMware Horizon View 7.10 and higher: RTAV with device splitting is recommended if Nuance audio channels cannot be used.
• To enable microphone button support for Philips and Grundig devices, contact your device vendor for drivers that support your virtualized environment; deploy them on the server/virtual desktop where your application is hosted and on the client PC.
• Microsoft RDS: When the Grundig drivers are not installed on both RDS server and client endpoint, the application using a Grundig device might become unresponsive when reconnecting to a session.
• Philips SpeechMike on Linux thin clients in a Citrix environment: Session reconnect might not work. Solution: Make sure SpeechMike firmware version 2.54 or higher is installed.

System requirements - edit controls*

*End-of-life: third-party environments

Support for third-party environments is only valid as long as they are supported by the corresponding vendor and might be subject to other restrictions. Please contact Nuance Technical Support for details. For more information, see the documentation delivered with the third-party product and supporting Nuance documentation.

When standard support by the vendor has stopped, Nuance will continue support if an issue is specific to the Nuance solution, within the limitations of the vendor’s standard end-of-life and Nuance's policy. This means that issues that are a combination of the vendor's component and the Nuance solution cannot be supported.

Dragon Medical SpeechKit product life cycle

Nuance provides support throughout the life cycle of one version and point release. Please note that Nuance will not perform problem analysis after the scheduled start of restricted maintenance. Dragon Medical Server versions released over three months after the dates stated here will not work with these client editions.
