    I have had an ongoing issue where when I connect my iPhone headphones to my macbook pro, the audio output will switch back to the internal speakers. It will only stay on the headphones if it is actively outputting audio. I took it to a genius and he said it is a driver issue with snow leopard.

    He suggested I reinstall with leopard and then upgrade to snow leopard from that, because the audio driver with leopard should work and it will not get replaced by snow leopard. Anyways I did not want to reinstall, so I installed leopard to an external hard drive and it seems to be working.

    I wanted to know if anyone knows where I can just find the audio driver file, so I can copy it instead of going through the whole reinstall process.

    Also, heres a video of the issue. I recorded it after the first time I took my computer in, it didnt seem to happen in front of the genius.

    Thanks

    I am on Snow Leopard 10.6.3 on a 17" Early 09 Macbook Pro.

    Disconnect the external headphones and Reset Your PRAM to see if it helps.

    Hmm that seemed to have worked. I remember trying before but it wouldnt reset because of my efi password, then I forgot to try after removing it.

    Thanks!

    False alarm. Its still happening. Anyway to copy the driver?

    Btw it only seems to happen with my iphone headphones. Has to be something to do with the headphone/mic port mix.

    If you have the "driver" download kext helper from cheetha.net and drag the kext into the application and hit easy install. Then go into kext utility and repair permissions.

    If you don't have the driver go into System\Library\Extensions\ on the hd you have leopard installed and look for the extensions aka drivers that deal with audio and use those files with kext helper on your snow leopard hd.

    I downloaded the kext helper and used it to install the kext's labeled audio, but after restarting it said there were no audio devices installed. Thankfully i had an old backup from time machine.
