Sound, no hardware devices found, on Laptop

Why have there been so many sound problems for so long. I do use HDMI for videos and sound, but if I shut down, then power up, why won’t the software find my sound device?

If I forget, which I frequently do, to choose the laptop internal sound before disconnecting HDMI and shutting down and leave the house, there is no sound. Whew!

Can you provide us with some information :
