WP 8.1 Lumia Icon volume

[Cep]

Hello, I've had 8.1 on my phone for about a month now and had no issues. I downloaded the most recent update for 8.1 two days ago and had no issues till today. I have a Nokia Lumia Icon and my volume, power, and camera buttons on the side of my phone just stopped working earlier today. I can do a soft reset to turn the phone on (it's super annoying but it'll work till Microsoft puts out a fix) but I can't find a workaround for the volume; any ideas? I tried getting a volume app in the store but none of them work for 8.1...
