I'm using the Desktop version with KDE Plasma. I'm trying to run a single command to fix my mic boost on user login.
/usr/bin/amixer -c 3 cset numid=27 1
/usr/bin/amixer -c 3 cset numid=27 1
To do this I've created a script file in my Documents folder and called it "FixMic.sh" then added it as a login script in System Settings > Autostart. I made sure the script file has execute permissions and tested the command in a terminal to verify it doesn't require sudo permissions to run the command. I've attached the error I get in the Autostart log.
