I'm playing with GNOME Wayland session and everything expect sound is working good for me (excluding some other minor bugs).
When on X, I can hear sound from speakers on my HDMI connected monitor but when I choose Wayland session it does not work. In both modes my headphones are working great.
My question is what should I do (configure/enable) or install to be able to hear sound from HDMI connected monitor under GNOME/Wayland?
Below I post some info about my system.

I am also experiencing the exact same problem. Can anything be done about this, or is this something intrinsic to wayland/Gnome?
Offline
I haven't found any solution yet. Currently I switched back to X because I was also experiencing GDM freezes when switching users and that was very painful for me (I had to restart my computer).
I think sound issues are related to how GNOME handles sessions in gdm-wayland-session. It looks like it doesn't initialize sound output device correctly. In X mode it does it.

It would seem that this might be a driver issue. I plan on investigating in the morning. Hopefully, switching to Catalyst will solve this problem.
Offline
I'm not convinced about your theory about driver issue because at last in my case, HDMI sound is working on X session. For both session types (Wayland and Xorg) I use the same AMD driver (radeon with firmware blobs) from the Linux kernel. I do not have xf86-video-ati package installed.
It is possible that GNOME's Xorg session "has better knowledge" about sound card and/or monitor internals and does some magic to make it work that is currently not supported by Wayland. I suspect it might be related to other issue I've encountered https://bbs.archlinux.org/viewtopic.php?id=209063 , but that is only my theory.

GNOME doesn't really do anything for your sound, but uses pulseaudio for it.
Can you switch to HDMI via GNOME's sound settings or pavucontrol under wayland?
Do you have the same issue with other wayland compositors, e.g. weston?
Do you have this issue also, if you start gnome on wayland from command line without using GDM?
Offline
It seems that Catalyst doesn't support KMS, so running wayland isn't even an option. Starting the session manually though
gnome-session --session=gnome-waylandalso yields the same result.
It's so strange...
[me@my-ShittyLaptop ~]$ aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono...actually produces no sound through HDMI, despite its output indicating otherwise. I'm trying to figure it out, but my google-fu is failing me atm. REALLY hoping this is not a problem with my ALSA configuration files. Lord knows that's a whole different can of worms...

Since pulseaudio works through alsa by creating its own asoundrc file, i thought the solution offered here would be successful, but i was wrong...

As of GNOME 3.20.2 HDMI sound (on Radeon HD 57xx) under wayland session is working as expected. It looks like it was one of the features that needed to be finished before wayland is usable replacement for X and now it's happening.
