My iPhone accidentally dropped into a plate of shallow water, the bottom half first. So the speakers and dock got soaked. Thankfully I moved fast enough that it didn't stay in the water for longer than maybe 5 seconds. There isn't any problem with my phone's screen or whatnot, the only thing is, the external speakers aren't working anymore. Music, sounds from apps, you can't hear it from the external. But it works fine through earphones. The ringing alerts work as well. What's weird is that when you try adjusting the volume with the rocker, the bell thing pops up but the bars doesn't show. What should I do to get it working again?
