IPhone 5S sound not working?

My iPhone 5s sound isn't working. It's not on silent or do not disturb; the sound only works when someone rings me but it doesn't work at all in music, text notifications, keyboard, Siri, or other app notifications. But they all work with headphones in. What do I do?

Should I pay 649 for an iphone 5s?

My father currently pays the sprint phone bill for everyone in my house including me. And our contracts all ended in July except his ends in October, and he's on this whole kick where he doesn't want a contract anymore and he's just being really annoying. All i wanted to do was get an upgrade and pay my 149 and be on my way. I'm 18 years old work in retail ($10 an hour luckily) and i work about 30 hours a week, and take summer classes two days a week until july 29th. Also the only bill i pay is 252 a month for my car note, which i give my dad in cash every month. I currently have 1,780 in my checking account and I'm really conscious with my money usually. So I was wondering if it would be stupid for me to pay for an iphone 5s in full (649) and just turn it on. I Feel like in the long run its not that bad because at least I never have to pay me phonebill right? (YET) lol. The reason I'm so pressed for a new phone is because its been a long while and my iphone 4 is hanging on for dear life… I need an honest opinion because I'm so conflicted right now.

Missed my second day of work?

I'll be brutally honest. My iPhone alarm didn't go off this morning because it's dumb as ****. But yeah, I overslept and today would have been my second day. Am I going to be fired? I don't even feel like making excuses to my boss. It was just a real case of oversleeping. I actually like this job very much. So is there still hope for me if I just go in and tell the truth?

My iPhone 5 power button stopped working?

So lately I realized it was harder to turn my iphone off. I realized this problem as soon as I downloaded IOS 7.1.2. Only the very edge of the left part of the power button is working. If I press the whole button it doesn't work at all. I also have to press it harder than usual to either lock it or turn it off / on. You really need help? What can I do? I have read about this on google, but all it said is to restart your phone (when I do that Siri turns on) or to replace/fix the button at an apple store, but really? It that even possible without either completely breaking the button or even the acctual iphone? Please I really need help… Quick! It's really worried and it's getting worse (harder to turn it off/on) every day.
