digital output dropping after ios 10.3.1 update

I just spoke to Apple support on the 'phone regarding this issue. If you can, please also raise a ticket over the 'phone for this issue so that the problem is highlighted as a priority.

The lady that I spoke to took her time to fully understand the issue, and that it's affecting a number of users. She scanned through this thread.

I pointed out that (as recommended by Oppo) Airplane Mode stops the issue from occurring, and that pausing the audio from the player and pressing play after a few seconds re-starts the audio stream.

I have this same issue.

I have an iPhone 6 with 10.3.2 using an OPPO HA-2.

It drops out after anywhere from 30 seconds to a few minutes.

I have tried airplane mode: no success.

I have tried various short (6 inch) and very long (10 feet) cables: no success.

I also have an Apogee One and it works perfectly with the Apogee one... no issues in any iOS rev.

it's typical of Apple to respond this way... they never admit an issue with their SW or products.

This is the reply I got from Chord. Basically abdicating any responsibility:

"We are aware of a software bug with iOS 10.3 and Apple devices, specifically the iPhone 7 where the audio will not come out of Mojo, but the track will continue to play, even when using the official Apple Lightning to USB adapter cable. Unfortunately this is a fault of Apple. We have reported this, and are hoping that they will be coming up with a fix, but cannot guarantee anything at our end. We apologise for any inconvenience, The Chord Team."

My Mojo has been rendered virtually unusable. I now have a £400 brick which Chord cannot guarantee will be usable after the next iOS update. Expect to see it on eBay soon. Fed up.

And what exactly were you expecting Chord to do to repair a problem in iOS 10.3 - a problem that affects a range of products including the MFI Certified Oppo HA-2?

Moreover early reports suggest the problem may be resolved in iOS 11. See my above posts. So I suspect someone reading this thread may be more than happy to pick yours up for a discount on eBay.

they need to be better at managing the software and support side of the business. Naim and B&W have dedicated teams that do this. Chord need to do the same. Where you are promoting product and software compatibility, you need to be proactive, not reactive. This is the sort of thing that differentiates organisations. Chord know that Apple constantly update iOS, but their approach seems to be to just wait and see what happens.

They're not "abdicating responsibility".

The problem lies squarely with Apple, whose operating system is dropping the digital stream intermittently. How do you expect Chord, a hi-fi hardware manufacturer, to deal with an Apple software problem, especially since Apple don't seem to be able to fix it themselves yet?

For most people, the Mojo is the most amazing magical device, and if you don't have the patience to wait a few weeks, then there will be plenty of people on eBay ready to grab a bargain.

Sounds like you work for Chord my friend. This is about Chord effectively and proactively managing key third party dependencies. It's a simple principle that applies to organisations across multiple sectors. Pointing blame at others for issues that customers experience when using their product is unacceptable in this day and age. At the end of the day, these things happen. My hope is that Chord learn from this and think about how they can prevent a recurrence.

I have no connection to any company in this thread. I also have an Oppo HA2-SE with exactly the same issue. There is nothing on Oppo's website to help with this, I had to speak to their support team.

It is an Apple problem, end of story. The problem is, people whinge in threads like this without picking up the 'phone and raising a support ticket with Apple. Unless many people shout out to Apple by raising a ticket, it won't have a high enough priority. Take 10 mins to call them if you can.

I may have some good news regarding this issue. I have, today, upgraded to iOS 10.3.3 beta 4 and the problem we have all been experience is no longer occurring.

This is after 4 hours of continuous use with an iPhone 5S and the Oppo HA-2. Previously, I would be lucky to get 10 minutes without a problem. If anything changes, I will report back. I am, however, hoping this is no resolved once and for all. Fingers crossed!

It seems Apple has changed coding in iOS, very possibly intentionally to further restrict its users to Apple equipment, without notifying companies who have designed and sold equipment as Apple iOs compatible. If that's the case, Apple should own up and let everyone know. If tApple is fixing the issue, it should let the companies and consumers know. At the same time, these companies -- Chord (I own a Mojo), iFi, OPPO, and others -- who now are fully aware that there is a problem are still selling their equipment to us, directly or through authorized dealers, as iOS compatible. I checked several of their websites today. That's just plain wrong for their customers. They, too, should own up and not continue to sell something as iOs compatible when it is not, even if their complaints about Apple are correct. They should get together and approach Apple as a group, with more force.

That's great to hear. I use my iPhone 6 for work, though, so can't risk taking a chance with a beta. I'll have to wait. I also hope the issue won't crop up again when iOS 11 is released in the fall.

I just read on MacRumors (while seeing when iOS 11 was going to be released) that Apple today "seeded a revised version of the second iOS 11 beta to developers for testing." If anyone tries it, or already has, could you let us know if our problem is also resolved there? Thanks!

The Apple recommended answer to the original post is inadequate. I too have this problem with an iPhone 7, iOS 10.3.2, Oppo HA2 which IS certified under the MFi scheme. Also happens with my IPad Air. This is a device which worked flawlessly during earlier versions of iOS, and continues to work perfectly if I use it on either my MacBook Pro or Windows 10 PC. There are multiple reports of the same issue affecting multiple DACs including MFi certified ones. A change in iOS has resulted in MFI devices not working as intended. While it is good news that people are reporting that this issue has resolved with iOS 10.3.3 beta 4 and early versions of iOS 11, it would be nice for Apple to acknowledge that they caused the problem instead of brushing it off as the fault of users.

I am sure glad I started this post. Thought I was going crazy a few weeks back. Let's hope it's all fixes soon so I can start using my Mojo again. On a positive note. I discovered the V-MODA Crossfade headphone.

I'm hopeful you're right. I got this email from Oppo support:

This will be something that you need to wait for an iOS update to resolve. iOS 10.3.0 added this error, 10.3.1 made it worse, and 10.3.2 has made the dropouts better. We have heard early reports that iOS 11 will fully resolve the issue, so you will just need to a wait a little longer for this issue to be resolved.

In the interim you can use the LINE IN on the HA-2SE or use a longer Lightning cable, such as the one that came with your iOS device, and setting the iOS device to Airplane Mode.

I don't understand how people are having luck with longer cables. I don't even understand why that would work, unless there's some pre-emphasis being programmed at the lightning port that has changed in a different iOS release.

I have tried multiple cables (different brands: apple, amazon, generic non-certified) of multiple lengths all the way from the tiny Oppo cable (6 inches or so) upto 10 feet and I see the same behavior with my OPPO HA2: it cuts out anywhere from 30 seconds to a few minutes.

If someone is having specific luck with a certain cable, I'd like to know which one.

Airplane mode also does not help at all for me.

What's weird is that I have the problem with the OPPO but not the Apogee one. But others here are reporting problems with the Apogee one. it must be something marginal in the electrical interfacing and apple changed some parameters for the port such as pre-emphasis or power levels.

Does anyone know when 10.3.3 is due out? I ask because it seems that some are having luck with it. I am not a developer, so I can't download the betas (at least that's my understanding).

I can only imagine how upset companies that make these DACs must be.
