I have an i5-11400 installed on ASUS Prime B560M-A, which included integrated graphics.
I was testing the CPU integrated graphics by removing my GPU and plugged the HDMI to the onboard integrated graphics.
There's only picture with no sound. I have to plug in a speaker at the 3.5mm audio jack for sound.
Is this normal?

How did you get the sound before removing the GPU?

What options do you have under Audio Playback devices?

I only got the Realtek Digital Output. The GPU HD audio wasn't shown because the GPU was removed.
 
It's the same audio source, the GPU card just takes the audio from the motherboard and route it to the built-in HDMI port.
No it's not, in video player software, vlc for instance, you can choose the audio device and play the audio through the GPU and it will be Independent from the system sound.

A iGPU could have sound as well in theory but I don't think there is any that does have it.

If your motherboard has HDMI port, you can try it too.
My motherboard does have HDMI port, that's why I plugged it in to try but no sound coming out, only graphics.

So is it possible to play audio through IGPU? or the onboard HDMI is only for graphics, not for audio?

Not all GPU have a proper audio card, it was the solution for the motherboards that lack the digital audio output. I had an old AGP video card that converts the audio to HDMI if you connect it to the motherboard's audio header. Pretty cool back then.
