There is something wrong with the touchpad. It will mute your volume constantly. It's incredibly annoying, this is a common problem. Gigabyte has refused to acknowledge me through countless e-mails, phone calls and forum posts over the past 2 weeks. I returned the piece of s*** keyboard a few days ago for one that doesn't mute my speakers constantly. I normally wouldn't make a post like this, but I've never experience worse customer service in my life (maybe Comcast is a bit worse). So if you've bought this model keyboard, please return it, there is no fix that I know of ,at least not one anyone from Gigaybyte feels like sharing. I can't speak for any other model of keyboard but the Aivia k8100 is awful, return it or better yet, don't buy one.
