Thank you for the information.
I personally have no problems with the current situation, so it's fine. My explanation was insufficient.
The points that I was concerned about are listed below. I apologize if they have already been made public due to my lack of research.
The first issue is whether the developer officially allows players to adjust the sound themselves. Second, is sound adjustment allowed in offline and online tournaments? If sound adjustments are not permitted during normal play or tournaments, I feel that the developers need to make further adjustments to the sound. Of course, the ideal situation would be one in which no one has to adjust the sound themselves.
I'm just posting random thoughts so don't worry about it.
