iPhone Water Damage (speaker works occasionally)

I recently dropped my phone in water and immediately took it out, turned it off, and placed it under a hand dryer for around a minute. I let it sit overnight and in the morning I turned it on and everything was working fine except when I went to play music, the speaker was not working. I of course checked to see that the volume was up and that it was not on silent as well as other settings, but still no sound.

I use my iPhone as my alarm as well so when I checked to see if the alarm was working, it was! It only worked for apple ring tones and ring tones with the .m4r extension. Though the sounds still worked for the alarm, not only does my music not play, but all my alert sounds for texts, mail, and other push notifications are also not working. When not on silent, the phone merely vibrates without sound.

What could be the problem? How can I resolve it?
