embedded audio won't play when hooked to HDMI and projector

The fact that this has worked well for you using other projectors suggests that the problem's not in your laptop, Windows, Powerpoint etc, but rather in the projector.

Perhaps the older projector supports video but not sound over HDMI, but the computer, seeing the HDMI connection, is still sending the sound out the HDMI port rather than to its own speakers/the earphone jack.

It's usually possible to scare up a PDF of projector manuals with a bit of searching on the web. That might shed light.

This page has some good troubleshooting suggestions; worth having a look:

Hi,



Thank you for writing to Microsoft community forum.



To have a better understanding of the issue, please help us with the following information:

1. Are you trying to output Audio via HDMI/headset or to a speaker/headset connect to your HDMI device?
   

Meanwhile, I would suggest you to update the audio driver and set HDMI Device
as default device.



Regards,
