Sunday i turned my ps3 played UC2 and fifa 10, then before turning my ps3 off i decided to go to the Psn store i was browsing it then a certain message start appearing on the bottom left of the screen flashing for like a 1 sec every 30 or 40 sec it was: Unsupported audio signal, Check ur device output. it remained doin this until i plugged the Hdmi from the ps3 then put it back, and the message disappeared, i played with my ps3 on monday nothin happened now i was playin with my ps3 , i played also UC2 and fifa 10 for like 3 hours , when i did exist Fifa 10, and was in the ps3 menu the message start appearing again like the last time, so this time i decided to plug the Hdmi from Tv and put it back and it worked and everythin came back to normal.

This doesn't look like a PS3 message, it's from your TV. Try a different HDMI cable to see if the problem is from your TV or the cable.
