ALC892 Yosemite - No Audio

[BakeTheJakeCake]

I'm getting to the end of my resourcefulness here trying to fix my onboard audio.

Quick background...

- I was working nicely on 10.9.2. Haven't had any issue since first building the hack last year.
- I stupidly installed the combo update to 10.9.5 maybe too hastily.
- I naively had changed my system definition to Mac Pro 6,1. I didn't realise the implications. I have since changed this back to Mac Pro 3,1.
- I've spent the last week trying to get the hack up a going again (not the Whole week
- I've now ended up on 10.10 Yosemite and 90% up and running again, but stuck with Audio. Can't get it going.

- I've run MB 6.1.0 to install the codec driver. Nothing
- I've tried the HDAEnabler and HDEFLayoutID in org.cham...
- Deleted HDAEnabler1 from S/L/E
- I've followed Toleda's instructions as far as I can understand them.
- The only fault flag I've found is in DPCIManager is not showing a Codec ID under Audio Devices.
- I reinserted kernel=mach_kernel - I'm not all too sure what this does, but I used to have it and now I follow an instruction to remove it at some point.

Any help would be great.... Maybe it's something quite simple. My CustoMac system seems to be really compatible judging by how easy it was when I first made it.

If nothing else I've learnt a few things from this If someone could give me some pointers, it would be much appreciated. At least I'm 90% back up

Thanks!

Is the issue no audio with acknowledgment of existing sound card in System Prefs? If so.. this is what got me going
http://www.tonymacx86.com/audio/143750-no-sound-realtek-alc-applehda-guide.html#post886717 <---Don't know if you were referring to this guide as the one you were following, got me up and working.
I'm using Clover with ALC892.. installed native AppleHDA, then patched using Toleda's tool, voila.. now I have audio!

try using MultiBeast for Mavericks install ALC892 .. then Go to System Preferences>Sound>Output
Check to make sure that Internal Speakers is selected.

this works for me!

Thank you both for your help. I've been through these steps...

I've put a problem solving request on Toleda's audio thread. Hopefully someone will spot the problem

Thanks,

Jake

Load the ALC892 driver in Multibeast.

Then load this program. Worked for me.

I am facing the same issue, what Multibeast version you used? And if you can show the correct steps to do it (before/after restart)
Thanks!

just install the driver from multibeast 6.1.0 mavericks version after fresh install of OS X Yosemite..and select internal speaker from your sound device you are good to go...

Thanks for the heads-up. Didn't work for me.

I ended up going through multiple methods suggested by toleda and finally struck lucky.

Thanks, didn't work for me for some reason. I had no Audio codec in DPCI manager. Installed with piker alpha method and all working now.
