Teams may freeze or fail to handle audio correctly when the Citrix optimization feature for Teams is not activated.
Additionally, if the wfclient.ini file on the device does not permit audio input, Teams cannot process microphone signals properly.
These configuration gaps lead to instability, freezing, or missing audio functionality during Teams calls.
The issue occurs because Teams Optimization is disabled in ELIAS or because the wfclient.ini configuration does not allow audio input. Without these settings, Teams cannot offload processing correctly and may freeze or fail to detect the microphone.


Devices running Citrix Workspace may experience Teams freezing, audio problems, or microphone not working when HDX Microsoft Teams Optimization is disabled or when required audio input settings are missing in the wfclient.ini configuration.
Enabling optimization in ELIAS and ensuring audio input is allowed in Scout resolves these issues.
A device reboot or refresh may be required after applying the changes.
Ensuring HDX optimization is enabled is essential for stable Teams performance on Linux-based Citrix devices. The wfclient.ini entry ensures that audio input is passed correctly to Teams.
