5728 (x86 and x64) sound issue with Audigy Card

On installing Vista (x64 and x86) no sound drivers were installed for my
Audigy 2 ZS card.

I installed Creative's version 2.10.0000 drivers successfully (I had to use
F8 - "Disable driver signature verification" to install on x64).

Using Creative's Audio Console I set up the 5.1. speakers; I then set up
the 5.1 speakers through Vista's Audio Setup.

The 5.1 sound system is working fine on both except that for the same
settings x64 is much quieter than x84.


Problem (both x64 and x86):

If you click on "Recording Devices" the Vista Volume Control on Systray or
click the "recording tab" on sound in Control panel fails with error:
"Windows host process (Rundll32) has stopped working"

Any Ideas

Thanks
Brian
