How to record headless chrome with sound?

Question

Google Chrome

Good day to all, the question is this: It is
necessary to record the browser page during the test and no matter how problematic it is, but you need to check if there is sound on the page at that moment, but headless chrome does not support audio output.
Maybe I'm not aware and some kind of launch parameter has appeared or someone knows how to achieve sound output.

Recording occurs through ffmpeg
The sound comes from the HLS stream
