PS3 game has no audio

Hello everyone! How is it going?
On tuesday night I was playing FF normaly, everything was working just fine, including the audio. However, when I logged on last night, the user name/password screen had bgm, but the main screen and the whole game was mute.

I checked my TV, checked my PS3, checked the audio options on Configuration tab in-game and everything is exactly the way they were on tuesday! O_O I even played other games to test if could be a system problem on my game system, but everything is as it should be.

Is anyone experiencing this issue? Can I get some assistance, please?

Thank you! <3
