Starting with Version 2010, the Citrix Workspace app for Linux displays all local audio devices that are available in a session. Instead of being grouped under the label "Citrix HDX Audio", devices appear with their respective device names. You can switch to any of the available devices dynamically in a session. Unlike earlier releases, you don’t need to select the default audio input or output before launching the session. Sessions update dynamically when you plug in or remove audio devices.

Starting with Version 2012, the enhanced audio redirection feature is enabled by default.

If you need to disable this feature, do the following:

1. Navigate to the <ICAROOT>/config/ folder and open the module.ini file.
2. Go to the clientaudio section and add the following entry:
   VdcamVersion4Support=False
