Using DisplayPort audio

Use the DisplayPort (DP) interface to connect your thin clients to the display devices. The interface can include audio signals in the same cable as the video signals. To enable the DisplayPort audio, ensure that you set up the following components:
  • A thin client that supports DisplayPort audio and/or dual mode with audio.
  • A display device, such as monitor, that supports audio playback in ICA, RDP, Blast, or the PCoIP sessions.
  • An analog audio device or a monitor integrated speaker.
To enable the DisplayPort audio on ThinOS:
  1. Set up a monitor with DP audio support.
  2. Connect the ThinOS client to monitor using DP cable.
  3. Plug the analog headset into the monitor DP audio interface.
  4. On the ThinOS desktop, click System Setup > Peripherals > Audio > Playback devices, and select the Enable DP audio check box.
  5. In the Audio tab, select either Port 1 or Port 2.
  6. Start either an RDP, ICA, PCoIP, or Blast session.
  7. Play a video, and check the audio output using the analog headset.
Limitations
  • ThinOS supports only the DisplayPort audio playback. Audio recording using DisplayPort is not supported.
  • DisplayPort audio is supported only on Wyse 5060 Thin Client and Wyse 5070 Thin Client.
  • By default, the DP audio is disabled on Wyse 3040 Thin Client. If you update ThinOS to a newer version, the default setting for DP audio is not set automatically. You must reset the thin client to factory default settings to load the default settings for DP audio. However, thin clients shipped with the latest version of ThinOS are already configured with default settings.
    If you enable the DP audio, and select the DP audio as the playback device, the following issues are observed:
    • A black screen is displayed for a few seconds during the system reboot.
    • DP audio stops responding, and a black screen is displayed when you play an audio file.
Limitations on the Wyse 5470 Thin Client
  • You must enable the DP audio as it is disabled by default.
  • HDMI, DisplayPort over USB Type-C port, and USB Type-C port audio is displayed as DP audio.
  • Hot plugging is not supported. You must plug in the HDMI cable, USB Type-C cable, or the DP cable, and reboot the thin client for the DP audio to work.
  • Converter is not supported.
  • Supports only audio over the integrated HDMI port with selected displays.
  • DP audio works when you connect a single DP audio supported display to the thin client through the WD19 docking station. If you connect two DP audio supported displays to the thin client through the WD19 docking station, DP audio does not work.
  • Turning off or turning on the display is not supported. Restart the thin client for the DP audio to work in the following scenarios:
    • If the power button is pressed, to power off, and then power on the display.
    • If the screen saver is set to Turn Off Screen.
    • If you click Apply on the Display setup window.
