mute button not working after scene is reloaded

Hello; I am using dontdestroyonload() Method, whenever the player dies and then I hit the replay Button or if I win and go to the next scene. all is working fine. perfect. but the mute button does not work anymore.

what can I do to make the UI Mute button work even if the scene is reloaded? I found some solutions such as using playerpref for audio.

I tried many scripts but no use. can anyone give me an example?
