No Zif cable lock / no sound

Thank you for pointing that out. I reseated the audio board and there is still no sound. I had never removed it when I installed the Ram. And I have since installed 4 others..Under Audio - No Built - in Audio.

That doesn't sound so good…Perhaps the Audio board went bad ?

If the board is not showing up it may well have gone bad. See if you can boot up from your original system installation disk holding down the "D" key and run diagnostics on your machine and let us know your results.

Thank you for getting back to me. I had to bring the equipment back to the client, since everything else worked. I will go ahead and order the audio board, Assuming thats the problem.

So I was able to run a Diagnostics and still no sound.Under Audio Built in - says No Built in Audio. Do I replace the Audio Board? If so , where can I get one? Or can you recommend a USb external speaker, if will that work?

Thanks for the email. Try this: boot up from an external USB or Firewire drive with a system like 10.5 on it. Check to see if it now sees an audio board. I believe failure to even see an audio board will cause failure of an external speaker. The audio board is Apple part # 922-7613, the speaker kit (which plugs into the board) is part # 076-1211
