How to include audio from the HDMI input

I have my Sony camera set up to record me while doing screencast tutorials. It's connected to Camtasia via HDMI that goes into a live streaming capture device.

This works brilliantly in OBS because the audio from the mic on my camera is included in the HDMI signal so everything synchs perfectly.

When I try to do the same thing with Camtasia there is NO audio included in the HDMI input. It doesn't show up as an audio input like it does in OBS.

As a workaround I tried recording the audio via a microphone plugged into my USB audio interface but there are major synch issues because it's coming from two different devices.

How do I get the audio that's included in my HDMI signal (coming from the camera) to show up as an option in Camtasia?

Thanks in advance

What does Windows see? Device manager should list the camera part under "Imaging devices" and the sound portion under "Sound, Video and game controllers".
Does Camtasia list your Camera? Does it see it as microphone also?
If your camera has a separate sound out port, something that can plug into your sound card? I suspect Camtasia cannot separate the sound from the HDMI video.
If your camera can record a session, you could feed that (video & sound) media to Camtasia for further editing.

On windows, you probably need something like voicemeeter from

With Voicemeeter , select the HDMI input on one of the inputs and route it to "B" (Virtual Out)
Then in Camstasia, select Voicemeeter as your audio source.

If you're also using a stand alone mic, you can add that to the Virtual Output as well.

I agree with jack to give Voicemeeter a try.

I prefer the more advanced Voicemeeter Banana

Both are Donationware and free to download.

I love the possibilities. I watched the video and wonder if there's enough life left in me to even bother? I think so, thanks Dubie.
