No. I just completed a server rebuild and within 5 minutes of playing the CBSN stream from the new server, the issue surfaced.
Logs have been submitted.
Also to be clear on this, I was watching the CBSN stream from their website on my phone while simultaneously playing the TVE stream on my Apple TV. The audio continued to play on the Apple TV while the video was frozen. My phone was playing the stream without any issues.
Nope. It doesn't look like it has that issue. Are you running the App Store version of the Apple TV app or the beta?
App Store version
This isn't isolated to just me:
It may be related... it may not. It’s always hard to see if something is related without having a lot of diagnostic details.
Could you update to the latest DVR beta? It has additional diagnostic logging that could help us track down what’s going on better. I think I understand what’s happening but it will help us confirm.
Once you’ve upgraded, when you reproduce it if you could send Diagnostics from the DVR and the app it should give us what we need.

I am running DVR build 2020.04.08.2010 and Apple TV app 3.2.35.
If you record the channel and play back the recording, does it have the same issue?
I do see a couple log messages about audio issues around the time that you're having problems, but generally when we see them in the logs everything will resolve itself fairly easily, so this is surprising...
There is no option to record these channels in the Apple TV app or on the web guide.
Sometimes using the playback controls to rewind and then ff will allow the video get unstuck but the audio has a lag of up to 1 minute or so.
Okay. We think we understand the issue but don't know how to solve it at this moment. We're doing more investigating and will update you as we know more.
Can you try updating the DVR to the latest pre-release build that was just released and then set your Streaming Quality to 8Mbps and see if that fixes it?
We believe we understand what is going on and are in the process of testing a fix for the Apple TV app that we will be releasing soon as a new Testflight beta.
Updated and set quality to 8Mbps. Made it through a couple commercial breaks without any issues. I will set back to original quality and continue to test. What can you share about the root cause?
Update: Issues occurs when streaming quality is set to original.
The Dynamic Ad Insertion platform that is being used by this HLS stream is using different MPEG-TS pids for the audio and video streams for the ad segments compared to the show segments.
Thanks for the explanation. Is the reason why this issue doesn't present itself when using the 8mbps quality because the DVR is transcoding the stream which equalizes the mpeg-ts pids?
Yes, it works with 8Mbps is because we shipped the potential fix to the DVR which does the work of fixing up the MPEG-TS pids.
I've just released a new tvOS beta via Testflight. Please download it and see if it solves your issues at Original quality. If you don't have an iPhone to use to sign up for Testflight, please email [email protected] with your Apple ID email address so we can add you.
You can read more about the changes in the beta here.
I will install the beta and test.
Will your fix also apply to the Android app and web player? The issue is present in both platforms.
Yes. The web player has the fix in the latest DVR pre-release you have installed and the latest Android beta also has this fix.
I can confirm the latest beta resolved the issue on my Apple TV. I had the stream playing simultaneously on my TV and my phone. My phone stream had the issue when the Apple TV did not. Thanks for the quick fix!
