Rendering video issue: audio off

[Instcfljx]

Hey so when i go to render my whole edit that i am completed with, i make sure the audio and everything is okay to go before hitting render. after rendering the video, when i okay it to see if it rendered okay, the audio is all off. im not sure what i did wrong. I posted in the comments the part of the edit I am talking about. even after rendering and going back to ae to see if its still lined up it is. I can explain more if needed. Any help is appreciated i am desperate. Im not that popular on tiktok, instagram so no one answers my dms. I am not sure what else to do I am very overwhelmed!

If you customized render settings or had your audio layer set to be a Guide layer (green #), the audio could be easily fouled up. We need to see your timeline (embedded, please, instead of Attached so we can see it) with the modified properties of the problem layer showing. We also need to see your render settings.

Well I already prcomposed the whole edit so there is no seperate layer now. On the ae itself it lines up but when I go to downloads to watch it that is when it messes up.

I also tried uploadind the video to show you but it wouldn't let me. I did attcah it to this of how it looks when I watch it after it renders

The video you uploaded has audio. I see odd frame sizes, and AE's H.264 rendering through the Render Queue is a bit sketchy yet. I would not use it. For H.264 files, I always use the Media Encoder, and I stick with industry-standard frame sizes and frame rates for comps and rendering. Send any social media outlet a video that does not match their standards, and it will be compressed with a sledgehammer. Most social media platforms have pre-made templates in the AME. 

If you are not hearing audio on the file you uploaded, there is a problem with your media player.

for the output module where you said the H.264 is sketchy, it doesnt give me the media option. Keep in mind I am extremely new to after effcts so all of this is confusing for me, I am unsure where everything is and how to work everything still. When I click the arrow beside the H.264 it only gives me one of these options ( in the attcahed photo). Also, I realized that when my edit is in the compostion box the video length is 17;04 and when i go to watch the video it alsways saves as 14 for the video length. It is somhow croppingthe video which makes the video faster and the audio of the video off. I am unsure how to fix it biut If there is no solution I cannot keep using this software.

also sorry for the miss spelled words! I forgot to reread before I posted.

I know the video I uploaded has audio, I am saying that after I go and watch the rendered video the audio of him talking and his voice is off. The video is also being sped up somehow since the length gets shorter. It was 17;04 in ae and still is when I pull the project up, just the rendered video gets cut down to only 14.
