"Read the forum" doesn't tell us anything.
A pi400 has several different audio configurations, it all depends on what you put in your config.txt file. We also need to know what extensions you have loaded. Also check dmesg to see if there are any audio related errors.

I just tried with Xorg-3d:
--- Code: ---speaker-test -D sysdefault:CARD=vc4hdmi0 -c2 -t wav -l1
aplay -D sysdefault:CARD=vc4hdmi0 /usr/local/share/sounds/alsa/Front_Center.wav
aplay -l

..works fine.
Following the above, running pavucontrol, which starts the dbus daemon and pulseaudio, xmms-pulse played music to the hdmi output without problems.

I have to remind to check the config.txt file to modify the device tree:
