[SOLVED] Systemwide audio mute

[pcurtis]

Hi All,

How do I perform a system wide audio mute (MUTE not just set vol := 0) on Windows 10?

I have indicators on my keyboard that show when the system is muted.

Thanks in advance.

hello,
you want to mute audio with a sendmessage ?
try this :

Code: Pascal  [Select][+][-]

1. // uses windows
2. // const APPCOMMAND_VOLUME_MUTE : Integer = $80000;
3. //       WM_APPCOMMAND : Integer = $319;  
4.   SendMessage(Application.Handle,
5.            WM_APPCOMMAND,
6.            0,
7.            APPCOMMAND_VOLUME_MUTE
8.            );          
9.  

Friendly, J.P
