iPhone 13 mini has crackling sound when using Apple CarPlay

Hello,

I'm having issues with noice and my Apple CarPlay: Every time I'm connected and playing sound, it's like there's a crackling/scratchy sound on top of the original sound. Here's som details:

• I'm using an iPhone 13 mini (which I started using from new in late 2022)
• It's the same issue across different cars (and car brands) all connected to CarPlay with bluetooth
• It hasn't been an issue in the past
• I've tried updating to IOS27
• I've tried removing the cars from my phone and my phone from the cars (in CarPlay)
• I've tried turning my phone (and the cars-systems) off and on and again
• Sound works fine across all other types of bluetooth devices
• I tried plugging my phone in with lightning cable to a car which has a multimedia-setup, but no CarPlay, and the sound is perfectly fine in that car
• In one of the cars I tried other people regular iPhone 13s, and the sound works fine

So in conclusion: I tried all I could figure out. It seems like the issue is about my iPhone 13 mini and CarPlay in general. And I don't know how to fix it.

Do any of you have the same og similar issues?

Do any of you know how to fix it?

Have a nice day :)
