There are lots of different analysts and streamers covering events. You can watch the ones you like better.
I think most of them do use a live board and an analysis board. Maybe you could mention the one you were watching.
I don't think you can get a ding because the whole system isn't set up to give a ding when a move is made. It's not an option.
Chessgames.com is a great place to analyze past chess games. Many of the greatest games have lengthy analysis pages.
I'm newly into chess, and I hate watching coverage of matches and tournaments. It leaves a lot to be desired.
Sorry I'm going to rant here.
First off, can we stop analyzing the match on the same board as the live match? This is super confusing, especially in a blitz or rapid game or when little time is left. It's hard to focus on where the last move was and where and when the next move happens.
On that, can the time be bigger? Can we get a ding when a move has been played? It's never clear when a move actually happens.
For OTB games, can we have a constant over the board view?
Where can we analyze past tournament games?
