Audio is stuttering and/or of poor quality when using a headset. It cannot be improved by changing software settings.


You may be using a headset with a 4-conductor audio plug on a device with a 3-conductor socket.


You can use all 4-conductor plugs (TRRS type) with the following IGEL devices:

  • UD5;
  • UD6;
  • UD7;

Some 4-conductor-plugs may not work properly with the following IGEL devices:

  • UD2;
  • UD3;
  • IZ3;
  • UD9;
  • UD10.

If this is the case for your headset, we recommend using 3-conductor audio plugs (TRS type).

4-conductor plugs are often used for mobile phone headsets that combine stereo headphones with a microphone. See the difference in the picture below (3 conductors on the left, 4 conductors on the right):
