Audio — Setting up Devices

Option 1: Via the Sound Settings

1. Create
   an audio application configuration. Create a new audio application and assign it to the desired thin client.

2. Detect
   audio devices on the thin client. On the thin client, open the menu and navigate to System → Sound.

   • The Hardware tab displays all detected audio devices and their profiles.
   • In the Input and Output tabs, view the available input and output devices.

3. Apply
   settings to the audio application Enter the names (or a unique part of them) into the audio application settings.

4. Apply
   configuration Restart the thin client to test the changed settings.

5. Correct
   errors, if error messages appear, adjust the entries in the audio application configuration accordingly and repeat step 4.

6. Verify
   the result, reopen the audio settings as in step 2 to ensure that the desired configuration is active.

Option 2: Via System Information

1. Create
   an audio application Create a new audio application and assign it to the desired thin client.
2. Identify
   audio devices on the thin client On the thin client, open the menu and navigate to System → System Information → Audio
   The following are displayed there
   :- detected sound cards
   - available profiles
   - input and output devices (Inputs/Outputs)
   

   
   The displayed input and output devices depend on the currently active audio profile.
   After booting, a default profile is usually active.
   Additional devices, such as HDMI outputs, appear in the overview after switching the profile, e.g., to HDMI. Therefore, specify the audio profile being used in the audio application.
   Ensure the desired profile is active before reading the device names.
   

3.  Transfer
   devices to the audio application Transfer the device names and audio profile from System Information to the audio application.
   

   Recommendation:

   • Use unique substrings instead of full names
     — this approach increases robustness against changes (e.g., kernel/driver updates).
4. Apply
   configuration Restart the ThinClient to apply the configuration.
   
5. Troubleshooting
   

   If devices require additional recognition or configuration, verify the active audio profile.

   • check the active audio profile
   • Check the device names / substrings
   • Adjust the audio application accordingly
   • Restart the system.
     
6. Check the result
   

   Open again:

   System → System Information → Audio

   Check:

   • Verify the desired profile is active
   • Confirm that the correct input and output devices are in use.
