Playing sound through Apple AirPods doesn't work
Sound is not playing through my Apple AirPods while preview clip on MacBookPro 15-inch, 2018. MacOS High Sierra. Despite AirPods are chosen as an output sound device, sound is playing through internal Speakers. Playing other media in other applications is ok - through AirPods.

I had a problem with the Bluetooth connection, so my AirPods didn't work. When I changed the settings, I fixed my problem. But unfortunately, I don't know the reason for your problem and I can't give you any advice. By the way, I want to say that I am very pleased with my AirPods, here https://woahtech.com/best-fake-airpods/ you can see a review of them. And as soon as I bought them, I couldn't connect them to the phone, and then I found out that it was a problem with the Bluetooth. Now my AirPods work great and I like the sound quality.

You should check if your airpods and phone are upgraded to the last configurations. Also check if your airpods are clean. A lot of dust, dirt and mud come into the airpods. Don't forget about bluetooth connection as well.
