Dear all,

I am writing today, hoping there is someone out there that has my board and has solved the issue I am having, so to start with,
My computer specifications are ....

Asus P5b premium vista
Quad core q6600 2.4
Ati 4500
8 gigabytes (2x4 sticks)
Ide disk drive
and a 10 000 rpm raptor (western digital) sata drive


What Works....pretty much everything, sleep, speedstep, full graphics, ethernet (which i just enabled using fakesmc (before i was using a altered kext to achieve this)

(easier to say what does not work....onboard Sound)

I run a pretty vanilla system, but currently I am using Voodoohda 2.61, which is the newest version i can use, anything newer and the outputs are silent, I have been working for months on getting on board sound to work (in a more vanilla style), in other words i have been trying to achieve full core audio, so i can passthrough dts and ac3 tracks to my amp, so far all the guides i have followed, have been fairly fruitless,

the most i can achieve is audio outputs shown in system profile and system preferences (and midi) but they don't actually work.....

I have attached my Dsdt that I am currently working on, if anyone has any experience with ad1988b or more specifically my motherboard, i could do with some helping hints :)

my dsdt was auto patched for a p5b (but i had altered it first for sound) essentially 2 sections have been added by me and that HDEF under pci0 and DTGP and the bottom, this is used in conjunction with ad1988b.fix.kext

thanks in advance

Edit, for some reason its not allowing me to upload my dsdt file, apparently i am not permitted to upload this type of file!

hey, thanks for the files and informtion, going to test it out now, just to let you know i saw you have a kext for your ethernet, not sure if it would interest you, but i have a line in my fakesmc which does that for me, not yet tested in dp4, but snow leopard works

also can you confirm that your optical out works? so far in lion its not working, going to try snow leopard shortly!

So I reinstalled Snow leopard on a spare disk, and updated to 10.6.7 (as on my main drive i run 10.6.8) all outputs showed in system profiler, and preferences, but did not seem to work, Does your optical work on your snow leopard install?

Hello,

I've have tweak VoodooHDA 2.7.2 to make work optical SPDIF on AD1988B

What is enable:

Green rear connector as output speaker.
Green front connector as output speaker.
Pink rear connector as input microphone
Blue rear connector as line input.
Spdif optical as ouput.

What is Disable

All other connectors.
But in plist.info

Tested on Lion, remove AppleHDA.kext

One trouble stay, you must go in midi tools to select 44100Khz frequency for Spdif.

Attached File  VoodooHDA.kext.zip   156.05KB   235 downloads

Regards

Fred
