Hi, I have an Apple TV and I use it for playing music on my phone wirelessly. It used to work perfectly fine till a few days back. I have connected the Apple TV to the Television by HDMI cable, and to my home theater using the optical audio cable. Now when I try to play music from my phone on the Apple TV, it plays it through the TV speakers and not the home theater, like it used to before. I checked all the settings but could not find how to change this setting. Kindly help!
