Hey there, I have a problem with my windows 7 laptop. When ever I run world of tanks (fullscreen) or war thunder (full screen), the sound works fine. And If I go Alt+Tab and work on something for 20min the sound usually still works. But sometimes, If I come back to a game I have minimized, the sound will have RANDOMLY STOPPED working! I go to the sound mixer and the volume is put up full, but there is still no sound coming from the game. Yes I do mostly use headphones. Yes I am quite sure that my sound drivers are up to date. Yes I have ran windows updates for the last week or two, (just turned them off because of the annoyance concerning delayed startup/shutdown). The sound works again, if I restart the game, but it is very hassle-some. Can any one help me? Thanks!
