does anyone have the kext of the above?, I only ask, as I bought a microphone that doesn't work with the standard AC97 kext, It records no audio.

I've set the input mic levels to high in sys preferences, but i can hear nothing in skype. its realtek ALC 850

Here is one I'm using:

Haven't tried the mic but everything else works fine, except volume level is always at ~50% on startup. I would like to have it at 100% but never found a way to fix this.

If you wish to try this kext please let me know if it change something...

Strange thing now, not only does my mic not work, but my headphones sometimes work, and its definitely software, as i know the hardware works.
