I have Realtek ALC850 sound card and the speaker jack works just fine but the other jacks (ex. headphone) are not working. This is what I could find out about the Audio for my motherboard:

AUDIO
· Karajan audio module
- Realtek ALC850 8-channel audio CODEC
- 6 audio jacks
- 1 CD-in connector
- 1 front audio connector
· S/PDIF-in/out interface

I have The LANPARTY UT nF4 Ultra-D motherboard.

Anyone know how I can fix this? If it is possible to fix. I have installed Leopard using Zephyroth's 10.5.2 dvd.

I have found out what the problem is. Nothing software related. Please close/delete this thread.

Author Update #2 @CyCLoBoT 2008-03-06

Well I can only use headphones if I unplug the speakers and plug in my headphones. I have two extra output jacks in the front but I can't use two (front and rear) at the same time.

At first I thought I had a separate headphone jack.

Field Note #1 @poilpoil 2008-03-07

I have ASRock 939Dual-SATA2 motherboard with ULi® 1695 chipset (ULi® M1695/ ULi® M1567).
My problem is my soundcard : Realtek 850 7.1channel AC'97 audio codec.

In Mac, it doesn't recognize because in sound I have no output and can't change volume bar.

During my installation I installed all drivers sound of Leopard 10.5.2 AMD.

Can you help me ?
Someone has this motherboard ?
Which kext do I install to have sound on my Mac ?

(Zephyroth, congratulations for your work . If a solution exhist can you add this in your PPF patch Rev.1 10.5.2 AMD EFI?)
