I know its not really on topic but here is what you could use for an easy volume adjust script
Code:
//Volume Changer Script - Compliments Genocide
alias "volumetoggle" "volumetoggleon"
alias "volumetoggleon" "volumeon; alias volumetoggle volumetoggleoff"
alias "volumetoggleoff" "volumeoff; alias volumetoggle volumetoggleon"
alias "volumeon" "volume 0.5; echo Volume Reduced!"
alias "volumeoff" "volume 1; echo Volume Restored!"
bind KP_DEL volumetoggle
Edit: I had tossed an echo in i was going to try to print to the screen, but that would require timed developer command and wont work without the wait commands that are disabled on skial. Was too lazy to remove lol.
Paste this into a new Notepad file. When you are finished editing, save it as a filename.cfg(insert whatever you want for filename, don't forget the .cfg). Copy this into your
Steam/Steamapps/YourSteamName/TeamFortress2/tf/cfg
folder.
Just change the 0.25 to whatever you want the low end, reduced, volume to be (0.01-1.00). This is the percentage of the volume bar. So as an example, 0.50 would be 50% volume and so on.
Adjust the 1.00 to whatever you want the normal level to be.
Change the KP_DEL to whatever key you want to use to toggle the volume.
