2 of my friends currently have the same issue ( one since 2months and the other since tonight)
When they're on the windows screen there is no problem. Again when they're not playing there is no issue, but at the moment they are playing (R6S) they hear us "lagging" and they cannot talk anymore. When they die they can come back and every round its the same issue..

Thx for your answer(s)

PS : Sorry for the english but i'm not english native ^^
