Problems with lip sync to recorded audio

I have had zero success in getting a man in my imade to lip sync to dialog in an mp3 file. I am using comfyui portable under Windows 11. Using LTX 2.3 . Tried a bunch of workflows that claim to do the job. (It works under Pinokio wrapper). Can someone use an mp3 file with a man speaking and see if you can make it works? I used video lengths of about 7 seconds.

p.s. I can make the woman sing to an mp3 song. It’s the man speaking. Help please.
