Mystery... No sound!... O/I card? Speakers? Logic board?

Text:

My MBP 4,1 (model A1260) stopped making sounds suddenly... I've read hundreds of posts on the internet but nothing seems to help. Here are some symptoms : - Built-in speakers don't make any sounds. - No sound coming from output jack (headphones or external speakers). - The mic (line-in) jack don't work either. - The power connection and left USB works fine. -NO RED LIGHT coming from headphone jack... so its not the optical speaker switch problem like most have. - In "system information", when I look in sound hardware... no description for input, output, etc... - I tried the Apple Diagnostic Software in the installation CD, the full extended scan... and nothing found. - Everything else works fine on my computer. My apple warranty is over :( ... Before I spend to much money at a computer store, anyone knows how to solve this mystery?? Is it the O/I card? Speakers? Logic board?? Thanks
