Lock Sounds & Keyboard Clicks Suddenly Quit Working

I have an iPhone 6 Plus. Last night both the lock sounds and the keyboard clicks functionality quit working. Everything else appears to be working just fine from what I can see. While this certainly isn't a big issue by any means, it is a tad bit annoying. Anyone else having this problem and if so did resetting work for you or did it require a full restore to factory settings? Thanks.
