iOS 16 no Audio using iPhone to HDMI adapter

RosujinRosujin Posts: 2 Spectator

I was watching spectrum tv just fine with my iPhone SE (3rd Gen) and the lightning to HDMI adapter. Then, I updated to iOS 16 and it immediately stopped playing audio over HDMI. I checked to see my phone was on mute or if the audio was turned down, but everything was fine. When I unplug the adapter audio plays over the phone speakers just fine. I can also play HDMI audio just fine using the YouTube app and other streaming apps. I hooked up my other phone (an iPhone X) and noticed that the phone needed to update the device firmware for the HDMI adapter since that phone had also been updated to iOS 16 today. It now also has the same problem. Could it be the new device firmware and/or the iOS 16 upgrade? Please fix this asap!

    Hi @Rosujin, welcome to our community!

    Do you have any issues with audio when using headphones or anything other than the phones speakers?

    Could you please try reinstalling the Spectrum TV app?

    Hi @William_M . My Apple AirPods work fine with the app when not connected to the HDMI adapter. Then, when I connect the HDMI adapter, audio cuts off from the headphones but does not transfer to the TV. I’ve tried reinstalling the app. I also just bought a new iPhone 14 Pro and it has the same problem with the SpectrumTV app. Other apps like YouTube work fine.

    Many of Apple’s users have recently reported the same & worse Lightning-to-HDMI problems with other streaming apps as well, including Amazon Prime Video, DirecTV Stream, Peacock, Paramount+, HBO Max et c., since updating to iOS 16, over on Apple’s support community. Whenever Apple fixes it, i wouldn’t expect the fix to necessarily apply to any 3rd-party manufactured Lightning-to-HDMI adapters that aren’t clearly advertised as being Apple MFi certified.
