Delayed start of audio when pressing play

Over the past few weeks I have noticed the following:
When I press “play”, the video starts right away, but the audio takes a second or two to begin.
If I pause, and then play, the same thing happens
The audio is in sync, it just doesn’t start on time anymore.

I have a mix of client devices, and they all behave this way:
FireTV
Apple TV
iPad
iPhone

Has anyone else noticed this?

Is it always the same source? What is the source?

I have noticed the same issue, but didn’t report it yet. It’s inconvenient to rewind every time I hit play, but that’s what I’ve been doing.
