Airplay
Cannot use AirPlay on either iPad or iPhone since OS 8.4 update. I have u-verse cable and a Denon receiver. Worked perfectly on both devise prior to update. I have restarted all devise to ensure that was not the proble.
iPhone 6, iOS 8.4
I Have the same problem with iOS 8.4, iPhone 6, and the Denon avr-x2100w. However, with my iPad Air, I was eventually able to get airplay to work with iOS 8.4 and the x2100w. Also, airplay works with the iOS 8.4 and my other receiver, a Denon aver 2112ci, using the iPhone 6 or the iPad Air. I had no problems with iOS 8.3.
