I own an hp ENVY dv7 notebook pc. Whenever I do steam chat/skype and im watching a video or playing a game the headphones will switch and the voice of the person comes through my headphones and the game sound goes through the speakers. I owned 2 headsets and they both did the same. I re-installed the drivers, didn't work. And I remember when i first got my laptop all sounds would go through the headset, but now that's not the case. I would really appreciate it if someone gave me a solution. Thank you.
