Yes. See Post #1/Unsupported/Non working Realtek ALC AppleHDA/3. Asus P8P67 3xxx BIOS: Phantom codec
Thanks Toleda, just want to confirm that i'm clear here... your analysis points to my BIOS as the reason for failure correct?

So the ONLY available solution, is for me to downgrade my BIOS: mobo AMIBIOS v.2.10.1208 (2011) from 2011 to an earlier version correct?

I will await yoru answer before even thinking of downgrading my BIOS, i'm not even sure its possible but i will read up on it.

I'm not sure what this number means: 887_v100201. Is this the version number of my AppleHDA.kext? (sorry to ask but i have no idea how to find out version numbers).

Again many thanks for helping me out. Champion!

Use search to find BIOS downgrade precedure.
887_v100201 is the audio codec and version.

Many thanks for clarification :thumbup:

Unfortunately downgrading my BIOS will remove CPU compatibility so its not an option. I've instead just used a spare USB soundcard to overcome the problem.

Thanks for all your help!

Not sure if zipping the files is the correct way of going about this... if not I can post the images directly. Thanks in advance!

1.Accidentally updated to 10.10.5 upon update I lost all audio devices. I have been able to roll back to 10.10.4 by installing over 10.10.5. I tried multibeast numerous times with the 898 driver install using various ID’s and random options with no success.

2.Osx 10.10.4/ GIGABYTE GA-Z77X-UP5-TH LGA1155/ i7 3770k/ GTX 670

3.What Codec? 898
Which Audio ID? Tried 1 2
What Injection? Chimera

Not related to the problem. Likely, the motherboard is not what you noted.
IOReg/DCPIManager says your codec is 892, not 898. Try MultiBeast/ALC 892.

I'm a bit embarrassed to be honest.... Looking back through my emails I have multiple versions of my mbo. I wanted the 5, but it was out of stock and ended up with the 4.... feelin kinda "special" right now. :banghead: Thanks!

3) Procedure used:cloverALC
4) Copy of IOReg: attachment: 04_iORed.zip
5)System/Library/Extensions/AppleHDA.kext attachment: 05
