Thanks in advance

Sorry, I don't understand what you are asking about?

Computer plays music/movie or reads a book. Some event switchs sound off.
Like a mute button on TV remote control.

Sorry for not answering (before now).

I understand the problem now, but I am afraid that I don't have a solution for it.

What's a pity!!!
It looks like Windows doesn't have a solution for it neither.
I use shutdown win command to switch computer off:

Code: Select all

shell_api::shellExecute(nullHandle, "open", "shutdown", @"/s /t 0 /f", "", windowsAPI::sw_hide)

There are win commands to switch monitor/keyboard/... off.
But I can not find anything about sysvolume.
It is possible to turn the media device off generally - this is too much.

So, nircmd.exe utilit is in use:

Code: Select all

class facts
        soundOff : varM{boolean} := { = VarM :-
                VarM = varM::new(false),
                VarM:modified:addListener({ :-
                        Par = string::format("mutesysvolume %u", if true = soundOff:value then 1 else 0 end if),
                        try shell_api::shellExecute(nullHandle, "open", "nircmd.exe",  Par) catch _ do succeed() end try }) }().
