Can anyone help me with this issue? I've been an editor for 5 years and I have never encountered such a thing. I was working on a project and exported it played back the file, to see if there were errors on the rendered file. Everything was working perfectly fine on my laptop. I uploaded the file on Facebook and played back it again to check if there were errors, but everything was fine on my laptop. I got a message from my teammate says the audio on the clip of the speech was missing. I was shocked and checked it again on my laptop and everything was fine and nothing was missing. I played it on my phone and I was surprised that there was no audio on those speech clips. I transferred the audio files on a different layer, but the same thing happens. No audio on other mobile phone and laptops, but there's audio when I play back it on my laptop.

Here's a screenshot of my timeline:

Here's a sample of what I am saying

Here's a video I took when I played the same link on my laptop
