Troubleshooting Citrix Client for Linux and Fixing Mike Support

Sometimes you find yourself in one of those situations when nobody seems to have an easy solution, so you have to find one for yourself. For instance, you may need to connect to your VDI, and start your Skype meeting only to find that your microphone is disabled (in Skype, in Control Panel > Device manager).

And the answer is
to add AllowAudioInput=True
to the section [WFClient]
of wfclient.ini file
of your Citrix client configuration

So, here is how to fix it in slightly more detail:

0. Prepare configuration supporting AllowAudioInput=True/False

  0.1 The settings must be there before the session starts.

  0.2 There are alternative locations to put this setting in, but you really need to
know what you are doing. Links to official docs are provided below.

  0.3 If your /home/$USER/.ICAClient is empty you need either to run the client once (let it fail if it wants, it is not important now) or create it manually together with the file.

  0.4 File templates can be found in Citrix installation directory, for instance, here: /opt/Citrix/ICAClient/config/wfclient.template


1. Don't use FF, FF only supports Web client, and I couldn't find a way to configure it. Probably, it is not possible, or should be done by Citrix admins.
Use CH instead.


2. Run your Web Citrix console. URLs may vary, in my case it was https://<CITRIX_HOST>/Citrix/OfficeWebHTML5 .


3. In the top-right corner click [You User Name > Change Web Receiver > Use Full Version (native Citrix)] .


4. Click your VDI icon, and save the .ica file anywhere convenient (file only lives until the session is open, then it gets removed automatically) .


5. Start new session

  5.1 You can start it by clicking on the fresh .ica file name.

  5.2 Or you can run it with ./wfica <FULL PATH TO YOUR FILE> (wfica is located under Citrix client installation folder, for instance, /opt/Citrix/ICAClient)

Configuration I used:

source system: Ubuntu Linux
target system: VDI on Windows
source browsers: FF, CH (no special plugins)
full client installed on the source system
