2. Add Nuance PowerMic device VID and PID to the Client USB device redirection rules Allow list
   
   Warning: The next step is a Windows Registry edit:

   • Back up the Registry before proceeding, reference How to Back Up and Restore the Registry in Windows .
   • Editing the Registry can cause the computer to become unresponsive on the next reboot.
   • Contact Dell Technical Support for assistance if you have concerns about performing this step.
3. If the published desktop is a server (ex. Windows 2016 or 2019), add the following registry key:

   HKLM\Software\Citrix\PortICA\GenericUSB key =>right mouse click => select “New” and select “DWORD (32-bit) value”, then type "UsbAudioEnabled" as the name and set the value to 1

Validation

After a Citrix VDI session is launched, the following validation can help to identify if the PowerMic is available for use.

1. THINOS device local > System Settings > Peripherals > Audio > no PowerMic in the list
   
2. VDI session desktop > Windows OS > Device Manager > sound, video, and game controller > PowerMic is showing
3. VDI session desktop > Windows OS > Device Manager > Audio inputs and outputs > PowerMic is showing
4. VDI session desktop > Windows OS > Sounds > Playback or Recording tabs > PowerMic is showing as enabled
   
5. Nuance Dragon Medical One desktop application > PowerMic is showing in Microphone drop down list

Composite USB Device Splitting Method

The following configurations must be provided to enable composite USB device splitting for a Nuance PowerMic device. This allows the USB audio driver support to come from the local client, and the USB HID button controls to be redirected to the Citrix shared host. This method provides more reliable audio effect when the Nuance PowerMic dictation feature is used in a Citrix shared host environment.

• Only the HID buttons are redirected into the VDI session. Other parts such as audio or microphone are kept in the THINOS local device.
• Nuance PowerMic product and Vendor ID
  • PowerMic II and Power Mic III > VID=0554 PID=1001
  • Power Mic IV > VID=0554 PID=0064

Citrix Host Policies Configuration

1. Set Client USB device redirection to Allowed
2. Add Nuance PowerMic device VID and PID to the Client USB device redirection rules Allow list
   
   

WMS group token policies

The following configurations must be provided to the Wyse Thin Client to enable composite USB device splitting for the Nuance PowerMic device. These configurations allow the client to provide audio driver support, while the USB HID button controls are redirected to the Citrix shared host.

1. Session Settings > Global Session Settings > Enable Map Sound
2. Session Settings > Global Session Settings > Enable USB Redirection Exclude Audio Devices
   
3. Peripheral Management > Expand to select USB Redirection > VUSB Force Redirect Settings > Add Row > Enter the device ID > example for Power Mic II or III enter: 0x05541001030000
   
4. Advanced > VDI Configuration Editor > Citrix Configuration Editor > Click Add Row
   1. File drop down list > select: module.ini
   2. Operation list > select: Add or Update
   3. Section > enter: ClientAudio
   4. Key > enter: AudioRedirectionV4
   5. Value > enter: True
      
5. If the following key to support Full USB redirection was added in the Citrix published desktop server, this key must be removed:

   HKLM\Software\Citrix\PortICA\GenericUSB "UsbAudioEnabled

Validation

After a Citrix VDI session is launched, the following validation can help to identify if the PowerMic is available for use.

1. THINOS device local > System Settings > Peripherals > Audio > PowerMic is showing
   
2. Citrix VDI session > Windows OS > Device Manager > sound, video, and game controller > PowerMic is not showing
3. VDI session desktop > Windows OS > Device Manager > Audio inputs and outputs > PowerMic is showing
   
4. Citrix VDI session > Windows OS > Sounds > Playback or Recording tabs > PowerMic is showing
5. Nuance Dragon Medical One desktop application > PowerMic is showing in Microphone drop down list
   Note:

   • For split configuration, Sound, Video, and game controller categories are not seen in the Device Manager for Windows servers, example Windows Server 2016.
   • If the PowerMic is not listed in the device manager Audio Inputs and Outputs category, cross-check the published desktop sounds Recording and Playback. PowerMic may have a disabled status.
