Music not playing with usb in car

My iPhone XR is up to date at iOS 15.2.1 and will not play through the aux port in my vehicle. I could play it prior to the update. But my daughter can play her iPhone 11 through the aux, she is also on iOS 15.2.1. I have tried restarting. None of the apps that play audio can play on my car, when they used to

I had same issue and got it solved thanks to another memeber post

the fix is:

go to itunes

download a song to iphone

conect to car via usb

let it connect

play that one song

then all other audio should be audible throughout car

Note:

(i had blue tooth off during the process)

That the exact issue I'm having I too have an XR and when hooked into cars USB port I get no devices connected yet it does show charging this is very frustrating as the only reason I use phone is to stream music in my truck and now that's not happening. I've called Apple support and they say it's a known issue and they're trying to find a fix I can't even downgrade to a lesser update

Ever since I got the latest iOS 15.5 my phone had lost its mind!!! It will only charge when it’s off, and when I plug it into my car stereo, the stereo doesn’t recognize it and switch to USB like it has been doing for the past 2 years. But when I turn off the phone and plug it into the car radio usb it charges it. So this HAS to be something wrong with the software that was caused by this stupid 15.5 update that installed while I was sleeping. I have since disabled automatics updates because this iOS has made my phone useless and in order to charge it I have to turn it off and plug it in for like 8 hours. It worked 100% fine before the update. I want my phone from 2 days ago back!! :(

Still having issues with dock in vehicle. Completely up to date. Used to work perfectly, then a few months ago music stopped working when using maps navigation. Now music just stops after about 30 secs. Really frustrating. It’s gotten worse with each update.

for some reason you have to have at least one song on the iPhone native music app to be recognized as audio source

I have had this issue for years. I recently discovered that it happens when Apple Music is NOT installed on my phone. When I download the app my USB is recognized. When I delete the app my USB is not recognized.

i had issues playing Spotify. Car would play the song when plugged in but as soon as backup camera or volume adjusted it would kick it out and constantly said “No media files detected.

Fix for me:

• deleted Apple Music from my phone, reinstalled. Did not restart phone.
• started apple music
• plugged into USB to car
• when the car auto played my Apple Music I closed the app, left it plugged in
• Started Spotify with no issues, worked perfectly!!

Hello Bigskyuk,

Thanks for using Apple Support Communities. We understand that you're unable to play music from your iPhone when connected via USB to your car. We're happy to look into this with you.

Please try the steps below:

1. "Restart your device and your car.
2. Make sure that your device is unlocked and on the Home screen.
3. If possible, try to connect using another cable or USB port. Check the manual that came with your car to learn how to connect an Apple device.
4. Check your charging port for any debris or damage. Make sure that your charging cable is properly inserted into the port.
5. Update your device.
6. Make sure that your stereo is using the latest firmware from the car manufacturer. Check your car's manual for more information.
7. Try playing audio from a different app. If you can't play audio from a third-party app, contact the app developer for help. If you can't play audio from an Apple app, contact Apple Support."

How to connect your iPhone, iPad, or iPod touch to your car

Have a nice day!

Well, I spoke too soon. Back to it’s old antics. Will play for a few seconds when docked and then audio stops. Cars system shows as still “playing” but no sound. Phone says stopped. When I hit play on phone audio comes out of phone speakers instead of cars system. Very frustrating

Same here, not working, I’ve seen a lot of other complain about this and contact apple and Apple doesn’t have a fix. So hopefully it is a software issues and the next software update fixes it. You can also downgrade to iOS 15.02 and people have confined that it works on that version but downgrading can get annoying.

Still having same issues after multiple updates. At this point I wish I could just select Bluetooth as an audio output option while docked. The dock being the audio output and charging and data link seams to be too messy.

Not the problem I’m having. This doesn’t fix intermittent playback. There is a deeper problem with app conflicts over dock audio output control or something. Very much like any other audio driver conflict.
