Mrx33

i have the card 610 gt
2gb vga dvi hdmi
it work 100%
fully reconigze
in aitkos mountain lion 10.8.2
using graphics enabler which is already choosen by default
so yes it works oob

this is to confirm the audio don't work in safe
i boot my computer in safeboot no audio
here are your options
do the exact samething i told before
but this time uncheck graphics enable
go to vga nvidia and check old cards
if that don't work
the problem is unsopported video card
you have to get a new card
or install lion
the kext works in lion and in ml too
you won't get audio untill you boot in normal mode

if you boot in normal remove applehda kext install voodoohda kext
reboot

the speakers looks gray
go to
system preference
sound
sound effects
select sound output device
headphones green front

output
headphones green front

now the speaker icon turns dark black
which it means audio is active and enable

try that i be back later today

i not sure if you get audio in safe mode
maybe is installed correctly but since you are in safe mode that's why is not showing up or working
you need to login in normal mode
ok let' s try again
i'm going to tell you how to install ml aitkos in g41mvgs3 r2.0
go to bios f2 o delete
in bios screen press f9 bios default
just change memory execution to enable
press f10
save reboot
do the samething you always do to install ml
erase the drive
make a new partion
mbr
journaled 'i don't remember the exact name but is the first option'
click costumized
this is the only thing you have to uncheck
uncheck audio
uncheck ahci

this is the only thing you have to check
check legacy logo
check no achi intel sata ide 'the 3rd one i don't remeber the name but that is the descryption'

when you login to the new fresh ml drag and drop the voodoohda inside kext utility

reboot

i have tested 8600 gt with lion and it works
so i think 8500 should work too

if you remember doing a diference selection that was the problem
most likely this time the graphic card and audio should work
that's what i do and everything works 100%
try that and tell me the results

the kext i gave you is for the board audio
you must have done something wrong
you mentioned a usb audio adapter maybe a conflict in audio
i been installing mac in pc since tiger 10.4
i have tested double check triple check and i know the kext works
if i wasn't sure i wouldn't never have uploaded
maybe you tried to many diferent audio kexts and something else is causing kernel panic
if you a video kernel panic you selected an injector
don't select injectors
select graphics enabler
if you have the usb audio plugged
unpplugged
delete the drivers for the usb audio
go to system preference audio and select green output
maybe that the option you missing
but i think the best solution is to reinstall aitkos one last time don't select any audio during installation
after you login with a fresh system
try the kext i assure you it works
or better yet tell me what you selected during the iatkos installion
and tell you what's causing the problem or the kernel panic
don't worry i have time today but i have to prove to all g41mvgs3 r2.0 that the kext works

are using lion or ml
i have iatkos lion and iatkos ml
the iatkos lion is easy but iatkos ml it has a little trick
1 bios setting has to be change and an update in bootloader to avoid the restart problem
after that then you can get to the installer screen and install
please tell me if the onboard audio kext worked for you
if you want ml in that board i can help you too
but you need to tell me if you have a video card or if you are using integrated onboard vga
i forgot to mentioned listen to music that's the audio really for
good luck
