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 display, that supports audio playback in ICA, RDP, Blast, or the PCoIP sessions.
• An analog audio device or a display integrated speaker.
To enable the DisplayPort audio on ThinOS:
1. Set up a display with DP audio support.
2. Connect the ThinOS client to display using DP cable.
3. Plug the analog headset into the display 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 the port.
6. Start either an RDP, ICA, PCoIP, or Blast session.
7. Play a video, and check the audio output using the analog headset.
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.
