Latest update no sound from phone to tv using adapter.

Hi MoneyMrBox,

We'd recommend resolving the issue by restarting your iPhone using the steps here: Restart your iPhone - Apple Support that are also below.

" How to restart your iPhone 6, 7, 8, or SE (2nd or 3rd generation)

1. Press and hold the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button until you see the Apple logo."

Best regards

Hello MoneyMrBox,

Thanks for visiting the Apple Support Communities and asking for help with watching Hulu with a connector.

Since it used to work from the iPhone but the update stopped it, either the adaptor is no longer compatible, or if other things work but not Hulu, then they protected their material and it can no longer be streamed from the iPhone.

"If an app doesn't display video or play audio

The app might not be compatible with your adapter. Check compatibility on the app's info page in the App Store or contact the developer."

The same would also affect the AirPlay without adaptors. This info is mentioned in this article: How to AirPlay video and mirror your device's screen - Apple Support

"Some video apps might not support AirPlay. If you can’t use AirPlay with a video app, check the App Store on your Apple TV to see if that app is available."

Thanks and have a wonderful day.
