I bought Portal via Steam -- at some point they released an update that added a small radio to each level playing a muzak version of the Still Alive song. Googling indicates this is part of an easter egg.

Is there any way to disable the music this radio plays? It's super annoying (to me) and ruins the atmosphere.

I've found mention online of a way to replace the looping_radio_mix.wav files on a PC, but

  1. I'm using Steam on a Mac
  2. I wasn't able to find looping_radio_mix.wav anywhere on my hard drive
  • The small radios have been there since start of the game... Messing with the Data of a game is never a good idea if you do not know exactly what your doing. You could eather turn the Musik in options down or destroy the radio in game. PS: There are achivements and hidden Audio Wave Pictures Coded in those little Radios

    @GEnGEr The radios were always there, but until the pre-portal 2 update they didn't play the the Muzak version of the Portal theme on every level. With the addition of these radios the mood and atmosphere of the game is changed considerably, and that change isn't to some people's taste. I'd like to play the game I originally downloaded.

I guess you have found this thread, they suggest a variety of methods for getting rid of the music, and one of them is replacing the looping_radio_mix.wav that you mentioned.

I wasn't able to find looping_radio_mix.wav anywhere on my hard drive

Could you describe how and where did you look for it, what else did you find (if any), or where does Steam keep its files on a Mac?

If all else fails, try voting and commenting on this Github issue, and hope you are raising the developers' attention to the problem.

  • Spotlight search for "looping_radio_mix.wav", find . -name 'looping_radio_mix.wav' in my ~/Library folder. Commented Mar 3, 2015 at 15:35

As you have correctly deduced, removing/replacing looping_radio_mix.wav is probably the way to go. On my mac (Steam defaults) all the sound files for portal are in this folder:

~/Library/Application Support/Steam/SteamApps/common/Portal/portal/sound/

Hit ⇧⌘G in Finder and paste the above path to get there. I don't have the file specified, but I don't know why. I can't open Portal right now and see if I have the music playing.
