Multiple Audio Devices Redirection
Overview
Citrix VDA for macOS has integrated and supported a new capability in HDX.
Multiple audio devices redirection
The feature allows multiple audio devices on the client machine where the Citrix Workspace App is installed to be redirected to the remote Mac VDA session.
With the feature enabled:
-
All local audio devices on the client machine are displayed in a session.
-
Instead of Citrix Audio Device, the audio devices appear with their respective device names.
-
You can select an audio device in an app in a session or use the default audio device during a session which is also the default audio device of the client machine.
-
If necessary, you can change the default audio device from the system settings of the client machine.
-
After the default audio device of the client machine is updated, the new device appears as the default audio device in the session.
-
-
Audio devices update dynamically within sessions when you plug in or remove one.
Configuration
By default, the audio redirection feature that allows multiple audio device support is enabled. To disable it, run the following command on the Mac VDA:
/opt/Citrix/VDA/bin/ctxreg create -k "HKLM\\System\\CurrentControlSet\\Control\\Citrix\\VirtualChannels\\Audio" -v "fEnableAudioRedirectionV4" -t BIN -d "0"
To enable or re-disable the feature, run the following commands, respectively:
/opt/Citrix/VDA/bin/ctxreg update -k "HKLM\\System\\CurrentControlSet\\Control\\Citrix\\VirtualChannels\\Audio" -v "fEnableAudioRedirectionV4" -d "1"
/opt/Citrix/VDA/bin/ctxreg update -k "HKLM\\System\\CurrentControlSet\\Control\\Citrix\\VirtualChannels\\Audio" -v "fEnableAudioRedirectionV4" -d "0"
Client Requirements and Settings
The feature is supported only for the following clients:
- Citrix Workspace App for Windows
- Citrix Workspace App for Linux version 2212 and higher
- Citrix Workspace App for HTML5 version 2306 and higher
- Citrix Workspace App for Chrome version 2306 and higher

Proper settings are required on Citrix Workspace App for the feature to function as expected. For more information, see the Citrix Workspace App documentation.
