Hi. This my laptop Model is: Alienware M18x Laptop
I plugged in my Xbox 360 into my Alienware laptop using the HDMI in. The video is PERFECT and I have no problem switching over to the video for my regular laptop and the HDMI video input.
The only problem I have is with the audio. I CANNOT hear any of the noise from my Xbox 360/Wii or whatever I plug in. I can only hear my LAPTOP itself, but I cannot hear my Xbox 360. How can I fix this problem? I have seen videos on youtube fixing this error with the Sound Blaster 3DI and changing the recording audio and some other things, but my laptop doesn't have Sound Blaster 3DI and when I went to download it from the dell website I couldn't find anything.
Tl;dr: I plugged my xbox 360 into my laptop with HDMI and I can't receive the audio. Please help
