My sound and menu are not working!

Well, like the title says one day I start up Garry’s Mod I press q my menu for the props doesn’t show up but my tools do show up. Another problem is I can’t hear a sound of an explosion like dynamite. I tried reinstalling and it didn’t work.

Do you mean that the explosive barrels dont make an explosion anymore either? cuz if so i have the same sound related problem, except my props work.

Yea and any kinds of explosions also I mostly want help with fixing my prop menu.
