No audio output detected!

[BigMacOS]

Hi,
I'm experiencing a weird problem since 3 days.
There is no audio at all in my mac pro. In the system preferences it says no audio output detected.
I searched the web so i :
- Reset the VRAM (commande option p r )
- I repaired permissions.
- I installed the lastest updates for my mac.
- I made sur it's not an earphone problem (the red light of death), because there is no sound at all with or without the earphones.

Now i know also that it's not a hardwar probem, because when i start my mac with the cmd+option+p+r it makes the starting sound!!!!

Please help me, i bought this 2009's mac 3 days ago and i can't even listen to music
Thank you

PS : i have Mac OSX Lion

What Mac OS X version do you use?
And what device is listed in System Profiler (System Report) > Hardware > Audio?

I have mac osx Lion and in the system -> audio : audio identifier: 0

What about a clean install of Mac OS X 10.7 Lion? As it is a used Mac, did the seller mention problems with the audio device?

This is a clean install of Lion, i had leopard on it before and audio didn't work in leopard neither.
Is it possible that it could be a hardwar problem even if i have the starting sound when a start my mac?

According to System Profiler it seems to be a hardware problem. Maybe investigate that further, since the audio identifier is set to 0.

Google linein for os x. My MDD G4 says I don't have a output line.

tried it, but it doesn't work, it says no audio device found. God...

If it's hosed in some way you can always get a low-cost USB audio device. Chances are it will sound better than built-in anyway.

Ok thank you for all your replies.
So for people who have the same problem as me and don't find a solution (and don't want to pay to repaire ) i solved my problem by installing AirPhones application on my iphone and Mac, so that the sound is streamed via wifi to my iphone.
This way i don't have a completly mute mac. But it can be only temporary, because it works only when your connected to wifi and you know the sound in the iphone is poor.
