apple hdmi tv adapter audio not working with ios 16

Hello NewMacbookProOwner,

Thank you for reaching out in Apple Support Communities. With the HDMI TV adapter, is it manufactured by a third party company or are you using the Apple branded Lightning Digital AV Adapter or Lightning to VGA Adapter?

If you're using one of the Apple branded adapters, we suggest to follow these steps as it can help resolve your issue:

Find out what to do when you have the following issues.

If you see video but can't hear audio

Make sure that you're using a Digital AV adapter (which has an HDMI port). If you're using a VGA adapter, it doesn't carry audio signals. To hear audio with a VGA adapter, you need to connect to the headset jack on your TV, monitor, projector, or stereo.

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.

If an alert says that an HDCP-compatible device is required

Your content might not be compatible with your adapter. Movies, TV shows, and certain streaming video apps require High-Bandwidth Digital Content Protection (HDCP). If you try to play these movies, shows, and streaming videos using a non-HDCP digital connection—like the Apple VGA Adapter—an alert will ask for an HDCP-compatible device.

If you need help with other issues

1.Disconnect and reconnect your adapter from your iPhone, iPad, or iPod touch and from your TV, monitor, or projector.

2.Make sure that your VGA or HDMI cable works, since the issue could be with the cable.

3.Remove any VGA or HDMI extension cables or converters. Accessories that convert a VGA or HDMI signals to different video formats (DVI, Composite, Component) aren't compatible.

4.Make sure that you have the latest version of iOS.

We look forward to hearing back from you with an update.

Kind regards.

Just wanted to come on here and let everyone know that update 16.3 just came out today. After doing the update all my streaming apps (Amazon prime, Hulu and Paramount +) all work fine. I now have sound and no more choppy picture. Finely!!! Hopefully if you do the update you will have the same results.

All,

While onsite to support a client with a Vaddio AV Bridge MatrixMix that wasn't passing audio from their iPad or MacBook I found that using the client's new Apple dongle model # A2119 (EMC3279) would pass HDMI video, but would not allow audio to pass from my laptop using a Mini-DisplayPort/HDMI adapter. I know the thread is about the Apple dongle, but bear with me.

After confirming the configuration of the device I chose to test with my older Apple dongle model #A1621 (EMC2877) and audio passed correctly.

It appears the client's new Apple dongle may have an issue in the updated iOS that locks up the digital audio and the only way to get audio to pass was to reboot the MatrixMix.

Once I locked it up again using the client's Apple dongle I confirmed that no audio would pass from any type of adapter and then cleared the issue using the A1621.

I even used the client's 3rd part USB-C adapter which initially worked correctly, but once the A2119 was used it would prevent audio from passing and wouldn't work until I used the A1621 dongle or rebooted the MatrixMix.

Once the older A1621 dongle was used and audio passed correctly I could revert back to the new A2119 dongle or other dongle and everything worked as it should.

The Apple store doesn't list the model number of the current USB-C Digital AV Multiport Adapter, so I wouldn't count on purchasing it from them unless they can confirm availability to the A1621 dongle.

I hope this helps, but if not, my issue may have been specific to the Vaddio AV Bridge MatrixMix.

It may also be relevant to reboot the TV/Display/Video component after you have the Apple device connected and powered on, but I didn't attempt that while onsite.

Good luck!

Pretty sure that everyone of us that is having this issue have tried everything. I have two two apple hdmi adapters and two hdmi cords. Checked tv and phone settings. None work. It’s all on apple. Thankfully they have another update, 16.3, that seems to be fixing this issue.

This issue affected me on my iPhone 12 with iOS16 and apple lightning hdmi adapter (A1438). I found a workaround in other forums.. basically, before starting the video start youtube (which works on the TV) then switch to your intended video source.

Audio Issue with Zoom on iPad using HDMI … - Apple Community

So, having a good look at the release notes for iOS 16.2, seems they did some work on the IP private relay. So follow that thread and as I was getting an error associated with VPNs on Disney plus even though I wasn’t running one at the time got me thinking. So I turned off private relay in iCloud, then in the Wi-Fi settings turned off private Wi-Fi address and limit ip address tracking. This has worked for everything other than prime video which I do not get sound and the picture stutters. Hope this works for you all. Any tips on getting prime working would be good.

I fixed problem by upgrading to iOS 16.3 just came out yesterday. Try it might fix your problems

After the update to iOS 16.3 the Apple HDMI adapter is working again as before on my iPhone XR.

So problem solved !

Yay! 16.3 fixed the issue! I can now stream Prime Video and Hulu!

I just upgraded to os16.3.1 hoping they fixed it. And YES! All issues resolved. My HDMI connection to iPhone shows video and can hear sound like before.

upgrade!

I didn’t fix it.

FIXING THE PROBLEM CAN ONLY BE DONE BY APPLE.

HELLO APPLE, ARE YOU THERE?

I recommended that the client abandon use of the new Apple A2119 USB-C/HDMI adapter because it was the root of the problem. All I can assume is the Apple iOS updates have caused an issue based on what I’ve seen in the thread.

My suggestion to the thread is to try the older A1621 adapter to see if it works or will clear the issue of no audio.

Although I have multiple types of adapters for use in testing client’s AV systems, I don’t have a Mac, iPad or iPhone that uses USB-C, so my experience was with the client’s equipment only.

My goal in adding to the thread was to provide some additional input to see if it was an effective solution, that is UNTIL APPLE COULD GET THE JOB DONE CORRECTLY AND RESOLVE THE PROBLEM THEY CREATED FOR THEIR DEDICATED CUSTOMERS.

HELLO APPLE, ARE YOU THERE?

I have had this problem since last night after a friend gave me the adapter. I am on iOS 16.2. I have just done two things, in accessibility I changed the allow while mirroring setting for zoom to allow and then restarted the phone. Holding the volume up and power button at the same time. Once the phone restarted Netflix and Disney plus worked as normal. Haven’t tried others yet. Hope this helps.

It is possible that the audio is not working with the Apple HDMI TV adapter on iOS 16 due to a software or compatibility issue. Make sure that the adapter is connected properly and that the TV's speakers are set to the correct input. Check if there are any updates available for both the adapter and the iOS device. If the issue persists, try using a different HDMI cable or adapter. If none of these solutions work, you may need to contact Apple support for further assistance...

Download iPhone update HDMI hook up now has sound and smooth motion. Good job Apple. I have the same model.
