A laptop has a integrated microphone. But we use an headset microphone. In the setting/Audio :
- both are activated. (it's different from xlite or eyebeam)
- when we test the input, sometimes the intergrated works instead of externet headset. Sometimes it switches to the 2nd one. It is not stable.
- Even we unactivate "automatic microphone selection, it's difficult to stabilize the choice
