So, with the recent update, the music volume setting keeps resetting from "zero" to "annoying" whenever a game is completed.
There should be no need to tell you how much this is inappropriate, because while people are waiting in queue they may want to watch a video or do anything else without having to turn off the game music every single time.
This is a reversal of the previous (correct) behaviour, when the music/sound effects setting were kept indefinitely once set, even after the client was closed.
I even went as far as replacing all the music files in game folder with empty files, but the game somehow manages to replace them with the original ones if I'm not quick enough when I log in.
I'm of course asking for the sound settings to be restored to their original behaviour.
