Limitations

• Only audio call is supported on the Wyse 3040 Thin Client. Video call results in performance issues.

  Workaround—Turn off the incoming video.

• Audio is still played through the first headset when you switch to the second headset during the call. This issue is observed when you have installed the JVDI package on the thin client.

  Workaround—Do not install the JVDI package if you are using Microsoft Teams.

• Call drops unexpectedly when you disconnect the USB headset during the video call. This issue is due to a limitation on Citrix Workspace app for Linux.

  Workaround—When your call drops, log out and log in to the session again. Do not disconnect the headset again during the video call.

• Headset is not automatically selected when you connect a new USB headset during the call. This issue is due to a limitation on Citrix Workspace app for Linux.

  Workaround—Select the headset device manually during the call.

• Sometimes you cannot receive the call or call cannot be established after you pick the call. This issue is observed on Citrix Workspace app for Linux.

  Workaround—Make a call from your end or wait for the caller to call you again. If the issue still persists, do any of the following:

  • Exit Teams and launch it again.
  • Log off and log in to the session again.
  • Restart the thin client.
• When using a headset, you cannot answer or end the call through headset buttons. This issue is due to a limitation on Citrix Workspace app for Linux.
