Problems in listening while playing videos from LEARN

Hello Team,

Is it just me or someone else is experiencing the problem to listen while playing the videos from LEARN section.

I am trying to watch videos from this section and for my surprise there's no voice in the videos. I checked everything on my laptop. I could listen other videos but not from this section.

any idea what's happening?

Thanks and Regards,

I can hear audio, on that one and remaining ones.

I can also hear audio on this one.

Try watching it from youtube instead?
