Hello Lizandra, At this point I definitely recommend heading to a local repair shop that has on hand a good microscope. The most common cause of no home button after repair would be tool-damage or a cut on the home button flex. The home button is so extremely fragile and even seasoned professionals can occasionally break it. A microscope with at least 10x magnification can help to confirm if the button is damaged. If so, the repair shop cannot replace the button. The solution would be to put the button back into the old broken screen assembly and install the old screen on the phone. Take it to an Apple store for standard screen repair. Apple replaces and programs a new button with every new screen they install. Now, if there is no damage visible on your home button, you may be in luck. The button plugs into your screen and the screen plugs into your phone. That means a defect in the new screen could be causing a perfectly good button to not work. This is a possibility even if the display and touch work. A functional new screen could still have a bad home button connection. In this case you could return the new screen to wherever you bought it and get a new part. Unfortunately though, your audio issue may be the real problem here and it may not be any fault of your own. Every consumer product ever made has some component that is just likely to fail first before the the rest of the device. In the iPhone 6, this was the touch chip, which you can read up on if you Google “iPhone 6 touch disease.” Iphone 7’s have a nearly identical issue, but this time it’s the audio chip. Local repair shops are starting to see this problem several times each week. Sometimes randomly, sometimes following a hard drop, an audio chip on your phone’s motherboard becomes disjointed and the audio system fails. This issue cannot be blamed on the owner even if you have taken apart the phone. It’s just a weakness - a design flaw. This issue can really only be well diagnosed by a local repair shop which may quote a rather high price to repair your motherboard. Even if you do not wish to pay for repair, I still recommend finding an experienced shop to at least ask their advice in person. Often the local repair shops will know MORE about these problems than the Genius Bar technicians at the Apple Store.
