Audio Stuttering / Poor Quality When Using a Headset
Symptom
Audio is stuttering and/or of poor quality when using a headset. It cannot be improved by changing software settings.
Environment
UD2/IZ2 D220
UD3/IZ3 M330C, M340C
UD5/UD6 H830C
UD7 H850C
UD9 TC215B
UD10 TC236
Problem
The line-out socket on the devices listed above is a 3-conductor socket (TRS). You may be using a headset with a 4-conductor audio plug (TRRS) of the OMTP type.
Solution
IGEL recommends using 3-conductor audio plugs (TRS) on the IGEL devices listed above. See the difference between 3- and 4-conductor audio plugs in the picture below (3 conductors on the left, 4 conductors on the right).
Alternatively, you can use 4-conductor audio plugs (TRRS) of the CTIA type. Placed on the second ring, the ground return (GND) has a proper contact with the socket.
For microphone signals, the separate mic-in port must be used.
