Today I wanted to join a meeting but I was unable to be heard.
I’m connected to a Windows desktop via Citrix Receiver, I’m connecting from an Ubuntu Linux host.
Looking at the sound settings in my windows desktop, I saw that there was no recording device. So not being able to send sound makes sense then.
To enable input sound, add the following line to the WFClient section in your personal ICA settings file:
[...] [WFClient] AllowAudioInput=True [...]
Next, log off and log back into to your windows desktop and check the recording tab on the Sound settings, there a recording device now.
That should do the trick.
