No Sound When Using a Display Port Monitor

Symptom:

You do not hear any sound from your IGEL UD5 or UD6 device. You are using a monitor connected via display port.

Problem:

Some display port monitors misleadingly report support for display audio although they do not have loudspeakers. Therefore IGEL Linux will try to play back audio via the monitor.

Solution:
  1. Right-click on the loudspeaker icon in the panel and open Sound Preferences.
  2. In the Output tab select Speakers / Built-in Audio.

    Sound Preferences

  3. Click Test Sound to test the new setting. Check if you hear a voice saying "Front Left" and "Front Right" on the thin client speakers.
