None of these steps shows an error or warning that something might have gone amiss.
Then I do the same you did, my output has audio&video.
-> No clue why your output does not, according to the logs it should have.
Did you check the right file? What player are you using?

Thanks for the tip. I was using VLC. Now I tried windows media player and IINA on MAC. Both plays sound well in this output file but VLC is not able to play sound.
Pretty weird but issues is resolved.
Thanks a lot once again for your support.

I didn't try other player than my default VLC as got bit sceptic with this msg display in Hybrid:
"Couldn't get free space in folder(), assuming zero."

I thought something is wrong with Hybrid.

That message is only important in case Hybrid is configured to check the space on the target drive before starting a job.
About VLC: have you tried updating VLC?

Got it.
Yes, VLC is updated.

Okay, strange no clue what's wrong with VLC, but it from time to time it has issues with mp4 files.
Personally, I'm using MPC-HC which works better for me than VLC.
When I use VLC I usually use the current nightly build (https://nightlies.videolan.org/). Currently, I would use the nightly build of v4.

Reading the changelog over at https://github.com/videolan/vlc/blob/master/NEWS regardint the changes from 3x to 4x, it states:
"Fix regression on some MP4 files for the audio track" <- this might be your issue, so trying VLC 4.x might help.
