Default OpenBSD and HDMI

I'm not sure if this should be here or in OpenBSD general. It seems to be a package thing

(https://srobb.net/stupid.mp4), but I digress.

I did a startpage (which I prefer to google for search) about this the other night, and didn't see much beyond some old posts on these forums, from 2020 or 2021.
At any rate, with FreeBSD, I can use pipewire, and if I hook up my laptop to the TV with an HDMI cable, I can play sound through the TV. With OpenBSD, I can't, though, to be honest, I hooked it up to the TV, saw it didn't work, then startpaged, found it doesn't seem to work according to what I found on the web and didn't try any harder.

So, I'm wondering if this has improved and if I can play both audio and video through the TV. (I can do video with no special configuration, it just works).

The logic that skips HDMI audio was put in place in 2009, according to the commit history of /usr/src/sys/dev/pci/azalia.c. You'll need to revise the source code and build your own modified kernels. If you're OK with doing that, you might be able to get HDMI audio working on your own. It's possible, according to this comment:

And here's the commit log regarding HDMI audio:
Code:
commit 41856ce868ef4f8a403cc66bbc033a9ff3f55422
Author: jakemsr <email redacted>
Date:   Sun Oct 11 00:07:06 2009 +0000

    this driver doesn't yet support HDMI codecs enough for them to be
    usable.  detach the driver if the device is only capable of HDMI.
    this keeps an unusable device from being /dev/audio0 (thus
    /dev/audio by default), while /dev/audio1 is fully functional.

Heh, it's probably beyond my meager abilities, and unless I have a long boring period of free time, beyond my will to do as well.

But thank you *very* much (as always) for a helpful answer.
