Help I am having random hl2 sounds in the background of my multiplayer session

Hello recently I am having random HL2 “Citizen notice announcement” occurring in the background of my gmod. This is very annoying while playing since I cannot hear people when I type “Stopsound” in console it does the job but only for 1 minute.
Please can you help me I dont know what to do or how to do it please reply back soon so I can carry on playing without that sound, It happens on all servers.

I believe theses are the sounds how to delete them ?

Does this happen on every server? All maps?

Its client side of course but I want to locate the sound files so I can either delete them or change them.

Try removing scripts folder in your gmod folder. I can’t think of anything else that would make this happen.

what happends if I remove it ?

Nothing bad, you are safe to remove it. All the required files in that folder are stored in the .vpk.

alright ill make back ups just in case
