So without realizing it I had shut off all sounds on the phone. As mentioned above everything worked fine on the phone and opened up like normal including the music player, youtube, etc, but no sounds. I went into settings and nothing was turned off there. I soft rebooted the phone, still no sound. then I posted here thinking I had accidentally pushed some weird combination of keys on the keyboard and used some unknown keyboard shortcut to turn off the sounds on the phone.
And then after racking my brain and getting really pissed off and ready to throw the phone directly into the back of my brick fireplace, I decided to try the volume buttons on the side of the phone, lol. And pressed the up button and sure enough the sounds came back on.
As mentioned above - I am an idiot, lol.
hahahha i was just going to ask that since i did that many times in the past with my mogul since the scroll wheel controlled volume......
