Just in case anyone else encounters this problem I have figured out what was going on. After exhausting everything I could possible think of I decided to do a factory reset and it worked!...well kinda. When I reset the tablet and went through the initisl samsung and gmail account setup, thr keys were tapping as they should be. Well after finishing the gmail setup the screen flashed, got brighter, then a notification flashed saying the system had been updated or something. The next screen was to setup my dropbox account. When I went to put in my login info I realized the key sounds were no longer working. I finished the setup, checked the settings and everything was checked like it should have been but still no sound.I decided to do another factory reset but this time skip the initial setup and go straight to the home screen. I then started setting my accounts up one by one. I have now gotten everything set back up and everything is working like it should. Im not sure what exactly caused the glitch in the system but am glad it's working properly now. Hopefully this will help someone in the futute since it appears im the only one whos had this issue thusfar.
