[SOLVED] Systemwide audio mute
«
on:
October 29, 2020, 10:02:25 am »
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]
[+]
[-]
// uses windows
// const APPCOMMAND_VOLUME_MUTE : Integer = $80000;
// WM_APPCOMMAND : Integer = $319;
SendMessage
(
Application
.
Handle
,
WM_APPCOMMAND
,
0
,
APPCOMMAND_VOLUME_MUTE
)
;
Friendly, J.P
