Problem with my PS3, is now solved, never mind

[Pagey279]

I started up my PS3 today to play some games, first I put in GT5 and did the update. But when the actual game loaded I had no sound.
I checked the HDMI lead, all fine.
I quit the game and went back to the main menu, lo and behold I had sound. The clicking noise as it scrolls through the options.
I re-started the game no sound again.
I had experienced this problem with GT5 before so I swapped to MW3, but no sound.
I quit back to the main menu, sound again.
I've put in a DVD and I have sound.

So basically none of the games I play have sound anymore, yet it was working perfectly 2 days ago when I went on it last.
Does anyone have any ideas what this might be? And how to fix it?

Never mind, I played with the sound settings and got it sorted!
