I can't hear any sounds from my Pi 4. I tried all speaker tests, I've changed my sound output to HDMI1 which I use, and tried all suggestions. The sound just disappeared, without any warning at all. I don't understand what happened. Anyone has that same problem? And any solutions?

I just found out that it was all a misunderstanding and that the sound was controlled by another device. All I had to do was turn up the knob. Can someone tell me how to close this?

Can you try this script? I found it somewhere on the here, but it's been a long time and I don't remember where it is. I had this problem too, you should just need to execute this once.
