Sound over HDMI Raspberry Pi - how to set it up?

Question

HDMI

Dear forum users! A couple of months ago, when setting up the Raspberry, there were problems with sound - it was transmitted through a 3.5mm jack, but the TV did not play sound via HDMI. As a result of digging through forums and sites, it was possible to solve the problem so that during startup, the TV indicated "(Raspberry PI)" in addition to the resolution, and the sound started. I recently changed the MicroSD with the system to another, but I can’t remember how I achieved sound transmission last time.
Please tell me how to do it?
