Audio button - audio listener

Hello guys,
I have a script that changes an integer from 0 to 1 when you switch a button from off to on and viceversa, and based on that, it disables/enables the audio listener from main camera (using playerprefs), and another script in each scene that check if the integer it’s 0 or 1 and so it keeps the option (so if u disable audio from menu, it keeps for whole game, and u can go to menu and enable it again).
Works fine, the thing is, I get this message in the console, like 50 times per second “There are no audio listeners in the scene. Please ensure there is always one audio listener in the scene”.
Is it something to be worried of?
Should I instead, make the script so that it disable all audios instead of disabling directly the Audio Listener from Main Camera so I don’t get error?
Ty all in advance

Instead of disabling the audio listener, you could also set the static AudioListener.volume value to either 1.0 or 0.0.

That way the AudioListener in your scene is still present, but its volume is just turned off.
