well i got a work around it’s not ideal i hope X devs fix this issue
the action command is specifically for kde for other DE’s u have to find
Also u have to install kmix application by kde it to work
in your /etc/acpi/events/mic-toggle :
event=button/micmute
action=sudo -u user XDG_RUNTIME_DIR=/run/user/1000 qdbus org.kde.kglobalaccel /component/kmix invokeShortcut “mic_mute”
things u should have installed are acpid and kmix
replace user after sudo with your username
