iPhone SE (2020) no audio signal output

[BitPerfect_]

I have tried to connect this iPhone SE (2020), using lightning > USB B > DAC and there is no signal output when I play a song from Apple Music.
The same setup using an iPad Air 4 (2020), a cable USB C > USB B > DAC, it works like a charm.

Any hint to make the iPhone work? I've tried to enable/disable the EQ, as I've read as a possible workaround but... no luck.
Thank you,

I don't know why the iPad works, but usually digital output requires the Apple Camera kit.

Connecting iOS Lightning to USB-B DAC

Hi all, This is a really basic question, and apologies, I'm sure it must have been asked before, though I couldn't find an answer. Is it possible to connect an iPhone to a USB-B DAC using a single cable? I've seen Lightning to USB-B MIDI cables advertised - would one of these work...

Ah, it's the USB C that makes the difference. No, this doesn't explain how I can use a Lightning connection to my car stereo.

Yes, I saw this post but reading other thoughts I've found that a simple cable will do the job (confirmed also by me using iPad).
So, in other words, USB-C is able to deliver the audio signal through the USB-B and lightning to USB-B is restricted somehow or ...?

Please tell us precisely what cable/adapter you're using to connect what DAC to your iPhone

These are the components: The adapter USB-B <> USB-C, the cable that is working with the iPad Air 4 (2020) USB-C <> USB-C, and the other cable that is not working with iPhone SE (2020), USB-C <> lightning.

You cannot use regular C->Lightning cables to plug a DAC into your iPhone.
You need a cable like this ("L to USB-C 15cm"): https://aliexpress.com/item/33009721024.html

Sorry, what’s the difference?
And why I am able to use this kind of standard cable with iPad connected to a DAC or with iPhone connected to a laptop to transfer data not only charging … !?

 

[staticV3]

The cable needs to have a special "MFi" chip (Made For iPhone) inside to tell the iPhone that it's safe to supply power to the attached USB accessory.
Apple's standard cables do not have that chip.

Make sense in this case, funny that is not apply also for iPad…

LE: sorry to say but, the above cables are Apple and according to this article, even the Apple standard cables already have MFi so..., I don't think that it's the cable. More than that, as I've mentioned, the cable is working fine connected to a laptop, the pop-up message about the connected device show up, I am able to accept or deny, and so on. I'll try to test another iPhone in order to eliminate the cable from this equation.

I have a similar situation where i can connect my iPhone 11 to my dac with Apples lightning camera adapter and it works great. But with my ipad (6 generation) I get nothing. Music plays through the iPad but doesn’t drive the DAC. I just assumed I need a powered USB hub but am too cheap to buy one.

There's a difference between an MFi-certified charging cable and an MFi-certified discharging cable.
The cable that came with your iPhone is a certified charging cable, but will not work in a scenario where your iPhone has to discharge via USB to power some accessory. Yes, Apple's MFi program really is that dumb.
Here's one such discharging cable: https://aliexpress.com/item/33009721024.html

@staticV3, do you think that this one could be ok?

This is not actually true. The camera kit only allows for charging.

@staticV3, do you think that this one could be ok?

I don't think you can plug Type-C DACs into your iPhone using that cable.
Here's a list of cables that can do that.
If you need something longer, consider buying this adapter plus any C to C cable of suitable length.
Or perhaps this 4ft cable from the same mfr.

Apple Lightning to USB 3 Camera Adapter & USB DACs

Hi Guys - I originally posted a question about using this adapter with the AudioQuest DragonFly Red (link). Since answering this question by purchasing the adapter myself, I've since discovered how cool this thing is and think a thread for the Apple Lightning to USB 3 Camera Adapter by itself is ...

audiophilestyle.com

but I don't what specific case to which you refer.

Would you please advise, the column B in the xls file is referring at ... ?
I think I'll purchase this one but first it will be interesting to know what 9038S/D versions means. Thanks,

It's a spreadsheet that I created for customers of the E1DA 9038S and 9038D, to help them find the right cable for their iPhone model.
Each colored cell links to a message in the E1DA discord server where people report which iPhone+cable+DAC combination has worked for them and which hasn't.
