Sound problem

Good Morning, I was able to see several people in the same case as me. So the problem is that the sound of my headphone is cut in one go so at first I thought it came from the dongle, but after several checks it turns out that it is the applications "Synapse 3" that is at the center of the problem for the good reason that when one leaves this application then the helmet gets back to working properly, I went through the motions to see if it wasn’t a parameter to cause this, but in the end, I didn’t see anything that could be the problem. To the pleasure of your answer. Cordially, Allan Meunier
