Thanx !
Hello All,
First, sorry if i double-post an already existing theme about getting audio on X48(T),
but i couldn't find any satisfying info till now, having searched for days.
I leave it up to our moderators to decide, if my request should stay in this section or just get purged.
I am so close to get a 100 % working Leo, that i finally decided to turn
to the community with a request - i just can't finish what i've started...
I aint's so skilled in Mac that i wish and obviously, cannot manage the issue on my own.
Although pretty impatient to try out Snow Leopard, i decided to stay with
Leopard 10.5.X for a while, having used it for an year or so.
The reason for staying with it is to first find-out, how would Leo work, after a recent hardware change that i did,
replacing my 5-year old (100% working) Pentium 4 rig with following components :
Mobo: Gigabyte GA-X48T-DQ6, Intel X48 + ICH9R
Processor: Intel Core 2 Quad Q9550, 2.83 GHz
RAM: Corsair Dominator DDR3 1600 MHz, 4x2 GB
Graphics Card : Gigabyte GeForce GTX285 1GB GDD3/512 bit
So, straight to the problem...Retail 10.5.6 install, using vanilla kernel.
Installation made on a GUID 1 TB drive (BIOS necessities foreseen and applied),
though not on the first partition (Windoze 7 went there, disk0s2), but after it on disk0s3.
Applied Chameleon RC2 boot loader, /Extra/Extensions is "stock", no adds/kexts/ or DSDT.
Onliest add to the /S*/L*/E* directory is Netkas's (THANX !) ATY_Init.kext, and official nVidia drivers
for the graphics card. Updated to 10.5.8 straight from ASU - went like a charm.
Now only audio is problematic. I think my mobo has just the same onboard ALC889A
as most P35/P45 Gigabyte boards, but 5.1 setup is not working, can't find what's wrong
or if i am missing something. No matter of which kexts and combinations i choose,
i can not reach more than just 4 channels working.
Audio system is also an old Creative Inspire T-something 5.1 Analog (i'm at work now, so
can't check what exactly it was) with the usual three "green, black, orange" lines (cables).
My case doesn't have a front panel, so only chance is figuring out, which of the
6 analog mobo channels on the back is causing troubles.
When configuring an aggregate device in Audio MIDI pane, it does show a 5.1 setup,
selecting 1 and 2 go for front L/R with sound, 3 and 4 for rear surround L/R,
and 5 and 6 (for center and subwoofer) - nothing. No damn sound coming out of them.
Ok, so far so not very good. Trying an HDRip movie with VLC - i hear exactly that 4
channels (front and rear) - ambient/surround noises/music, but no main speech.
Apparently, in this setup the line out (green) and rear (black) are working,
but not the orange (center/subwoofer).
Interestingly, when i unplug all cables and plug only the center/sub - orange cable into the
green line-out, center speaker and subwoofer come out immediately.
This is so noobish and i feel so stupid with this now
So close to the full 5.1, just this messy 4 channel thing.
Any hints on what i might have shot down and killed, or might have missed installing/configuring
will be highly appreciated.
Thanx in advance to anyone that might give a hand solving this silly issue,
and/or point out a proper kext package/install method for this mobo !
