So I made some changes to the audio drivers and software on my computer. After upgrading to Windows 8.1 I found that a lot of my drivers were actually reset to the default manual drivers. This really screwed up some things on my laptop. However, I went to the Realtek website (which is the manufacturer for my audio drivers) and downloaded the latest driver which included compatibility for Windows 8.1. You may lose some functionality provided by Dell. However it is also possible that Dell's audio software for me was attempting to raise the volume at the same time, causing the volume to be raised in four steps instead of two. Regardless after installing the latest drivers (which I think disabled Dell's unnecessary software) my volume now increases as it is supposed to- in two steps. Hopefully this helps others. If you have any questions, I'll try and help out the best I can.
