Ok I have a really annoying problem with my computer. So one day I get on my computer to caht with some friends on Skype so I plug in my Turtle Beach X-12 headset, for the first time, into the microphone and audio jacks to chat. I finish unplug my headset and turn off my computer. Next day turn on my computer, no sound, I mess with the volume, still nothing then I plug in my headtset and now the sound works through my turtle beaches. I have tried all the options and I dont know what to do so please, tech gurus of the internet, I ask for your support to help fix this problem for it is quite annoying. For clarification, my computer is an ASUS, my audio runs through an HDMI cable and my monitor has built in speakers and its brand is NEC.
