Citrix Workspace - no audio options, microphone not working

  • 772

I am trying to enable my microphone in Citrix Workspace for Linux:

https://docs.citrix.com/en-us/citrix-workspace-app-for-linux/whats-new.html

https://docs.citrix.com/en-us/citrix-workspace-app-for-linux/get-started.html#preferences

I can connect with an ICA file, but am unable to add an account, so I am unable to follow the steps for me to configure the microphone.

Is there another way to configure Citrix Workspaces to use my embedded microphone, or if I plug in a USB one to use that?

  1. Have you enabled audio input in the wfclient.ini? add this

    [WFClient]
AllowAudioInput=True

    The wflient.ini file can be found under ~/.ICAClient

  2. Here is a detailed guide how to make Citrix Workspace and MS Teams in it work with Ubuntu host:

    Instructions

    Step 1. Download and install Citrix Workspace for Linux

    Step 2. Trust third-party certificate (optional)

    Some organizations use certificates from authorities not present in Citrix Workspace distribution. In my case it was QuoVadis, following steps make it registered with Citrix client.

    # Download the certificate in PEM format
curl https://www.quovadisglobal.com/wp-content/files/media/qvrca2g3_pem.pem \
  -o "qvrca2g3_pem.crt"

# Make sure the CA certificate file is owned by root user and group, and
# it has `-rw-r--r--` or `644` as the file permissions
sudo chmod -v 644 "qvrca2g3_pem.crt"
sudo chown -v root:root "qvrca2g3_pem.crt"

# Copy the certificate to the keystore
sudo cp -v "qvrca2g3_pem.crt" \
  "/opt/Citrix/ICAClient/keystore/cacerts/"

# Rehash contents of the keystore
sudo "/opt/Citrix/ICAClient/util/ctx_rehash"

    Step 3. Fix detecting audio devices in Microsoft Teams

    • Install libc++1-12 and libunwind-12 on the local ubuntu (22.04) host:

      source "/etc/os-release"

# Commented out since apt will complain
# curl -fsSL https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add

# Recommended solution
curl -fsSL https://apt.llvm.org/llvm-snapshot.gpg.key \
| gpg --output  "gpg-pub-gpg-llvm-snapshot.gpg" --dearmor
sudo mv -v "gpg-pub-gpg-llvm-snapshot.gpg" "/usr/share/keyrings/"

# Commented out since apt will complain
# sudo add-apt-repository \
#  "deb http://apt.llvm.org/${UBUNTU_CODENAME}/ llvm-toolchain-${UBUNTU_CODENAME} main"

# Recommended solution
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/gpg-pub-gpg-llvm-snapshot.gpg] http://apt.llvm.org/${UBUNTU_CODENAME}/ llvm-toolchain-${UBUNTU_CODENAME} main" \
| sudo tee "/etc/apt/sources.list.d/llvm-org-${UBUNTU_CODENAME}.list"

sudo apt-get update

sudo apt-get install libc++1-12 libunwind-12

    Sourcing /etc/os-release should provide the UBUNTU_CODENAME variable. If it does not work you need to replace it with the respective codename, jammy here in this case for Ubuntu 22.04.

    Step 4. Enable pulseaudio support in Citrix

    • Navigate to the /opt/Citrix/ICAClient/config folder and open the module.ini file as root.

    • Go to the [ClientAudio] section and add or modify so you have the following entry:

      AudioRedirectionV4=True

    • Restart the session for the changes to take effect.

    Step 5. Enable microphone in Citrix

    • Navigate to the ~/.ICAClient folder and open the wfclient.ini file.

    • Go to the [WFClient] section and add the following entry:

      AllowAudioInput=True

    • Restart the session for the changes to take effect.

    Opinions and more tricks

    Making audio work is the most complicated part - sometimes you need to unplug your USB audio device from linux machine and plug it back while having the Citrix connection up. Also pavucontrol tool may be helpful in configuring which device should be used by Citrix for playback and recording. Install pavucontrol with:

    sudo apt install pavucontrol

    Video worked for me “out of the box”, without any hacking required.

    Some more tricks:

    • Set up automatically choosing the right audio device as a default playback and recording source in Windows when starting Citrix session: on your linux host goto ~/.ICAClient folder and edit wfclient.ini file by adding [ClientAudio] section at the bottom of the file. Put one line in that section AudioDevice=\<Jabra Link 370\>. Replace "Jabra Link 370" with the name of your device, you can get the name by launching pavucontrol on linux and looking at the Configuration pane.

    • Many users will be using Gnome so the following should make things easier working with keyboard shortcuts (via ArchWiki):

      gsettings set org.gnome.mutter.wayland xwayland-grab-access-rules "['Wfica']"
gsettings set org.gnome.mutter.wayland xwayland-allow-grabs true
