Ok, finally got it. Not very elegant, but it works for me at least.

But here's the story first, as it may not work for everyone:
1. I discovered that my old Realtek drivers from April (5254) installed
properly on Vista x64. No more red x next to the speakers! But sound playback
was very distorted. Hmm I thought.
2. I took the following driver files from the x64 Vista released by Realtek
a while back(5252) and overwrote the same files from the 5254 installation.
Here are the files:
CPLUtl64.exe
RtlUpd.exe
RtlUpd64.exe
RtlCPAPI.dll
RtkHDAud.sys
RTKHDA64.sys
RTCOMDLL.dll

Probably not all of these are needed, but who cares about figuring out the
exact subset when it is already working!?

3. I think discovered that this worked with the newest 5257 build. So
basically, it is the inf files in the Vista setup package that is broken and
not the drivers themselves. This might be because the 5257 and 5254 inf files
are digitally signed while the Vista package's is not.

So basically, to recap, copy the above listed files from the Vista WDM
folder and overwrite into the current x64 drivers for XP 64 from Realtek.

New Vista drivers from Realtek for 64 bit is expected soon ( this is just my
speculation ) as they just put up new 32 bit drivers for Vista today.

I am having sort of the same problem. I get the drivers to load
properly, but no sound. Drivers are getting a signal, but no sound
output. I downloaded the latest 32bit driver and still nothing.
 
Check if the Realtek analog output is selected.
If you are connecting ALC88X to analog speakers you can have no sound when
digital output is selected.
See your sound device property in the control panel.
