I haven't had to 'replace' kexts before. Will it overwrite the old one or should I be finding, deleting, and reinstalling it? My sound randomly stopped working a few days ago, several others are having the same issue with my board. ud5h 898.

898 isn't spoken here, you need an 885. The answer to your question is MultiBeast takes care of delete, install, permissions and cache.

thx!

Thanks Toleda - successfully upgraded to ML and after days of trying to fix my previously working audio, I finally found your instructions and got my 889 breathing life again - WAHOO! You guys suffer for your art!

No Audio

I've patched my dsdt and installed the relevant patched AppleHDA from MultiBeast, still got no audio on 10.7.4

Attached is my dsdt and the ioreg is at :https://www.dropbox.com/s/3jv2e8iwzvyzr7l/raunaq’s Mac Pro.ioreg

Could some kind soul help?

You did everything right for the wrong audio codec. This thread is for the 885 (also labeled as the 889a). You have the 889. Change the layou-d to 0x79, 0x03, 0x00, 0x00 and install MultiBeast/Patched AppleHDA/ALC 889. More info, Optimized AppleHDA for Realtek ALC 889 on Lion - Update.

Worked perfectly, I'd somehow managed to forget what codec I had
Thanks for the great advice!

Hello,

I've followed instrucctions on the first post and rear panel is working perfectly, but the front panel is not working (mic/phone), my mb is GA-EX58-UD5 and i'm attaching ioregistry.

Runing 10.7.4 as my gtx 285 performs better in this version.

Dmesg output:

kernel[0]: Sound assertion in AppleHDAEngine at line 2520

Is it possible to make the front panel work?
Thanks
