No sound on Sony WH-1000XM4 when it connected both to iPhone and MacBook
I have headphones Sony WH-1000XM4, iPhone 12 Pro Max and MacBook Pro 13m2. When I connect my headphones both to iPhone and MacBook there's no sound I can hear from my iPhone by the headphones. What can be the reason of the problem? There's no problem when I connect iPhone and iPad.
