Publish Video doesn't include Audio

Hi everyone,

We are currently using Captivate 2017 for a non-responsive project. We read the varying posts. To date:

1) We do not autoplay and we have a poster image

2) We tried publishing straight to Youtube option; no audio.

3) We used the publish settings to publish as a video, no audio.

4) We altered the bit rate to see if that made a difference, it did not.

5) We added a second before every slide and republished as a video as well as a YouTube, and that did not work.

Any other ideas? We are using PC/ Windows 10 Enterprise.
