On the top of your screen, you'll see a white arrow with white dots either side, click on this.
Choose Home. This will take you out of Citrix without signing you out.
Make sure on the bottom right where your sound is that it hasn't got an X. If it does this means that the volume is muted.
If muted unmute.

Click on start.
Type settings.
Click onto sound.
Make sure the correct devices are chosen.
You can also go to sound options by following this way too:
