Iphone 13 Streaming Audio/Video

Hi there, altc173.

Restarting your iPhone 13 was a good first step to take. Do you notice the issue to continue if you connect your iPhone 13 to another internet network (mobile/cellular data or another Wi-Fi network)?This can help show if the no video and audio issue is from the internet network having issues or if the issue is something else.

Connect to a Wi-Fi network

1.) From your Home screen, go to Settings > Wi-Fi.

2.) Turn on Wi-Fi. Your device will automatically search for available Wi-Fi networks.

3.) Tap the name of the Wi-Fi network that you want to join. Before you can join the network, you might be asked to enter the network's password or agree to terms and conditions.

You'll also want to ensure that all installed apps are fully up-to-date, which may also help since the latest app version will be installed:

Take care!

I was having this problem, too, and noticed iphone / ipad (both iOS 15.6.1) appeared were trying to connect to my airPod Pros, even though they were in their case in another room. I removed the airPods from the case and put them in my ears - got the battery dead sound. I put them back in the case and pugged them in to charge, and apps are now working normally. Problem fixed for me.
