outch, sound vanished..

Hello, i was working in the first person controller, well the prefab in standard package, but from one momment to other the sound stop working, now is mute, the weird thing is when i test de sound with play button (sound graphics waves) works fine, but when i start the game inside unity the sound does not work…, is weird too because when i stop the game a “ticc” sound is listened, like the original sound but just a cut.

I restarted the engine and the same, going to restart Windows now… maybe…

someone has the same problem?

i respond my self… i forgot to set audio listener…
