iOS 18 Beta 2 Carplay Music Problem

I have a similar issue. My CarPlay is a wired connection and I get NO sound. No music, podcasts, Siri reading texts… I can see it on the screen but nothing else.

Same issue here. I had it with beta 1 and it could be fixed with a reboot of iOS or the carplay device. However this issue persists after reboot

It seems to fix itself after a while this is only for CarPlay wireless I have no clue with wired connection it took about like 5-7 minutes to fix

I have the same problem with this beta update. Music on Carplay no sound on all apps, Spotify, Apple Music and Youtube music

While listening to music via CarPlay (with discussed issues), you may try to make a phone call. After ending the call, iPhone will switch with an accordance to the Bluetooth profile. As a result, music quality should be fixed.

I realized that when I have this problem, on the iPhone the sound comes in mono. It only comes out of the handset. It doesn't come from the speaker, it's like I'm making a phone call.

reboot does not work but I will try the method mentioned by @Robustez. making a phone call while listening to music may be the solution.

by the way, when you make a phone call while listening to music, sometimes the music starts playing behind the phone call. has anyone experienced this problem? (ios 17 had the same problem)

I only get audio from the phone.
non-CarPlay Bluetooth works fine.

when the phone connects to CarPlay audio is only available from the phone speaker. ( ie not via the car stereo)

same here, sometimes it plays music through a poor "Voice" sound, and others it will just play through phone. unplugging and plugging in multiple times will eventually fix it. Also noticed Spotify goes missing sometimes.

I also have this issue on a wire carplay and i think the fastest way to fix it is to clic and hold power to open siri and then just cancel siri it will make carplay crash and restart and then evrything work

I have the same troubles With the sound. In both cars apple car play isn’t working. BMW CarPlay is wireless and the Kia Car Play is wired. I can connect it, but everytime when I want to listen to music or something else the sound comes from my phone instead of my car speakers. I can control everything via CarPlay but the sound is just coming from my phone…connect and disconnect isn’t helping. Restarting my phone isnt fixing the problem too

I found that simply activating the voice assistant fixes the issue

Same issue as above - wired connection in my Toyota Rav4 - displays as if in CarPlay mode but sound comes from iPhone instead. Takes a bit of wrangling - namely physically removing the USB and reinserting it a few times and eventually it will come back over the car speakers instead.

Yeah I’m having the same problem as mentioned by others but apple carplay doesn’t display as an option for me to even use. I plug in my iPhone in my 2023 Mazda 3.

I wonder if this is related to the volume bug in iOS18 that got worse in beta 3. i have noticed when you open an app that has audio it will work at first but if the app gets interpreted by anything (Ads / Notifications) or if you leave the app to switch to another then the audio will just stop. Since it seems to effect all apps it could be what is happening here, or even carplay is adding to it.

This issue has been present from beta 1 . music stuttering , it comes and goes as it pleases , only way to fix is restart iOS . I’ll try the assistant To see if that temporarily fixe: the issue .

same here. honda accord XM radio becomes enabled when my iphone connects to carplay

I am experiencing this same issue on my 2024 Honda Ridgeline BE and iOS 18 Beta 4 re-release.

We really need a fix for this. In my experience, ever since iOS 18 Developer Beta 1, only after making a phone call, the audio in wireless car play on my BMW 3 series is extremely choppy. I have to disconnect and reconnect the phone from my BMW menu to fix it.

There is a serious problem with iOS 18 and CarPlay that Apple has not addressed yet

I have had the sage issue with ever beta since ios16. Resetting my cars infotainment system seems to fix it. Unsure about other cars, but if I reset my Mazda system by holding the music button, nav, and volume button (mute), for 15-20 seconds, it works again after the recor reboot

Same issue with public iOS 18

iPhone connected to CarPlay gives sound like mono or something through car dynamics and without any method to change loudness. it doesn’t work both on iPhone or car audio system. Just same stable level on music with disgusting sound

sometimes the sound goes through iPhone itself regardless it shows CarPlay connectivity and CarPlay as sound speaker

some manipulations give an unstable result but even if it plays well, couple of minutes later the bad stuff start again

it should be fixed, I can’t use CarPlay now because of that very unstable

try to turn off vocal/voice shortcut. fixed for me

Same issue here. very annoying. Couldn't use maps and music together as wireless carplay doesn't allow to use google maps. Please fix this asap

My wife’s phone has encountered this issue with her upgrade to iOS 18 (non-beta).

Mucis acts as if it’s in a phone call (volume cant be turned all the way down and only front speakers pipe music): the phone‘s volume doesn’t show the standard CarPlay icon; and at times music only plays out of the phone whilst controlling play/pause on the car. As some here reported, playing on the phone sometimes resolves on its own after a few minutes of it being connected.

it seems that the audio handoff to CarPlay isn’t happening or when it happens it’s identifying it incorrectly as a phone call/notification. 2019 Chevy Traverse, iPhone 15

I have the same problem. I’m new to iOS, and this seems like a major bug. How long could it take Apple to fix it? CarPlay is unusable like this.
