when I'm having a conversation on Skype with someone, and i start a game, sometimes (not always) my audio just stops. sometimes it's my skype conversation that stops (most of the time this is the case), sometimes it's my game, sometimes it's both. i fixed it once by just rebooting, starting skype conversation and starting the game, but sometimes even this doesn't work. what I've found by Googling is going to playback devices and then to communications, and setting that option to 'Do Nothing'. That's now the case, but the problem still persists.
