I have produced a video in mp4 format.
The sound plays ok right through ok in PowerDirector365 edit mode.
The sound plays ok right through ok in mp4 on the PC.
When I copy the mp4 to an external portable backup HDD The sound plays ok right through on the PC.
When I play the mp4 on my Smart TV from the portable HDD the sound drops out on the final scene.
If I stop the play and restart it in the final scene the sound is there.
It seems there must be a break (which I can't find).
I have tried cutting a small piece from the previous and last scene but that hasn't worked.
I have tried re-rendering.
Perhaps the error correction on the PC is better than that on the TV ? But still need to find a solution.
Any suggestions appreciated.

In your case, I would try to change the audio format, it might work.Create a profile from what you chose by switching from AAC to Dolby Digital see photo
There is no guarantee that it will work, but it does not hurt to try.

Thanks AVPlayVideo for your prompt suggestion.
I went away and put my thinking cap on (it often helps)
I went thru the timeline frame by frame at the problem point and coudn't find any gap.
So I re rendered the mp4 file as MKV and it now behaves.
The mp4 profile : MPEG-4 640x480/25p (6mps) Aust PAL
The MKV profile : AVC 720x480/24p(8ms)
I noticed in checking my timeline that my frames are 24 per second.
Maybe this was the weakness.
