Question

Just installed iOS7 and now my Airport express is no longer working. Very frustrating. Who has a solution to this problem.

Answer 1

I'm curious what's happening for others with Airport Express devices that aren't working. In my case, it's simply now impossible to get sound coming out of it. All my devices and computers initially THINK it should work - they all show the Airport Express. But when I try to play, it doesn't work, with slightly varying responses:
iPhone 5 and iPad 2, both on iOS7: if I choose the Airport Express, they continue to play as if through the Airport for about 20 seconds (with progress along the little progress/scrub bar), and then just stop playing. No error message or anything.
On my computer, through iTunes 11.1: it thinks for a while, with the "Connecting to ___'s Airport Express" thing going at the top of the screen, until I get the "An error occurred while connecting to the airplay device ... the network connection timed out" message. The little chevron (?) in the upper left side, that lets us "Choose which speakers to use", becomes orange rather than blue, and when I click on that, the Airport Express listing now has an exclamation mark inside a warning sign.
On an iPhone 4, with iOS6: basically the same as with the iOS7 devices. It seems to "think" it's playing through the Aiport Express, and then after about 30 seconds just reverts to the iPhone speaker and stops playing, with no error message.
Note that through all this the Airport Express has its green light and seems to think it's working fine, with an "Excellent" connection, according to the Airport Utility.
I've tried turning basically everything off and on; everything is as up to date as I can make it, except that iPhone 4; I've forgotten and added networks; I've reset network settings; I've added and taken away a password from the Airport Express Airplay speakers (because, hey, why not). I'm not sure what else there even is to do: maybe tomorrow I'll head in to an apple store and see if I can use the AirPlay from my iPhone to play on one of their Airport Expresses? If they even have any set up?
Outside chance of the cause - could my wifi network somehow be confused because it's dealing with both iOS6 and iOS7? Does that make any sense at all? (Not that my wife is going to be the least bit eager to upgrade to iOS7 after hearing me swear profusely over the past couple of days!)
