So I was experiencing sound issues with the laptop when I first bought it. About a month ago I came across this post 
which helped me get the sound working on my laptop back to 100% functionality. It required me updating the bios, which I updated to version 01.10.00. This update was released on 08/02/2016 and I did it on that day. Since then my sound was perfect but the volume rockers on side my laptop are working in opposite. If I press increase sound goes down, and if I press decrease the sound goes up. It wasn't like this before the update. Its been about a month and that's the way its been since. Its a little bit annoying so I wanted to know if there is a way to fix it or do I have to wait for another Bios update to be release or something else. Any input is appreciated. Thanks
