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.
