Mountain Lion: MultiBeast - No Audio/Solutions and Problem Reporting

[twistedsystems]

Yes I have found the issue. When you have the much needed npci=0x2000 or npci=0x3000 that was needed for LION to boot in your Chameleon.boot.plist it will kill sound on rebooting system. Test this by removing the one you have and try to boot. But please follow the post I just posted. Everyone will need to be as vanilla as possible and run the combo update 10.8.5. Then run the scripts that Toleda has available for us all to use. Heads up: Some of the boards still require a npci=0x2000 or so to boot up. Take out your current 0x2000 and 0x3000 flags out of org.chameleon.Boot.plist and try to boot without. If one fails try the other at the boot screen with either -npci=0x2000 or -npci=0x3000. Mine booted fine without either.

so after following the post #1 - i assume I have found out pertinent information....

attached screen shots and ioreg.

I don't have a iohdacodecdevice@ 1B 0

it also appears that my pin configurations is not the same as the ones in post #1

I don't exactly know how I should address that but....it appears that and the device 1B, 0 are the problems...

Please advise...Thanks.

Remove npci=0x2000 or npci=0x3000 if you have that in your com.apple.boot.plist. it kills the audio upon boot up. Try that.

Won't that jeopardize my resolution on my Gt640 video card ?

Please advise..

You have a different problem. Audio is working on your system, you have the x79 no sound problem. See Note 3, Unsupported/Non Working Audio ML Optimized AppleHDA in Post #1 of Mountain Lion: Optimized AppleHDA for Realtek ALC8xx.

The fix has been found. One must remove npci=0x3000 from the org.chameleon.boot.plist file.

THANK YOU!

I have a Gigabyte EP45-UD3P motherboard, and have been using the 0x3000 kernel flag. Changing it to 0x2000 fixes the problem (it doesn't boot otherwise).

This + toleda's patched AppleHDA (via Multibeast).

Removing ncpi=3000 fixed my audio problem as well!!!!!

Static is a grounding problem: case, motherboard, power supply, peripherals, etc.
