As the subject says:
First off, I have a gigabyte motherboard with onboard direct channel and optical (I use optical/SPDIF) and Logitech X-540 speakers
When I got the speakers - they installed flawlessly, the realtek control panel immediately picked up that it was "Dolby Digital Surround"
Not 2/4/6/8 Channel Speakers
I rebooted many times, etc still no dice so I finally reinstalled the drivers.
The sound works now, but not with Dolby Digital 5.1 surround - I dont even have the option in RealTek anymore, it flat out doesnt exist.
I'm running on XP 64 bit
Thanks in advance guys, really appreciate it.
