Question Audio barely audible on phone's speaker but fine on earpiece - multiple phones!

[kingkong_11]

I am facing this really weird phenomenon.

This is from a YouTube live stream that I produced. There is a long chain with too many components to find fault with and I seeking suggestions and brainwaves to narrow down the search.

The current situation is that watching live and playing back the YouTube on PC (laptops) is fine for everyone that has ever viewed it.

On more than five Android phones of different makes and models, playing the exact same url, the audio is barely audible and badly distorted through the phones' speakers. However, on these phones, when a ear piece is used, whether 3.5mm jack or USBC, the audio is fine through the ear pieces.

Any suggestions that can explain what is happening are much appreciated.

Please link the video. How did you create the video? Which file formats and codecs were used?

Try the youtube app and not the browser url
