No output through HDMI

The problem: When connected to the TV via an HDMI cable, I cannot choose the output device to be the TV, the only output devices shown are "Speakers", "Headphones (unplugged)".

My first try at a solution:
I tried to follow the steps in https://wiki.archlinux.org/title/PulseA … DMI_output

 aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC294 Analog [ALC294 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [LC40LB601U]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

But when I try to test which one of these is the actual HDMI output via

aplay -D plughw:0,[3,7,8] /usr/share/sounds/alsa/Front_Right.wav

in none of the instances do I hear any sound.
