The first thing I did after I exhausted my own troubleshooting ideas was to search these forums for possible fixes. I tried all I could find (see my original post above). If you see any I've missed, please let me know.
In the mean time, I found Creative's bug list
for these beta X-Fi drivers. One user isolated a similar problem on his system by reducing his RAM to 3 GB, at which point the problem disappeared. (However, he was running XP64 with different processers, motherboard, and X-Fi model.) I tried removing the ReadyBoost RAM on my system to no avail - not surprising since I still have 6 GB of RAM installed on my motherboard. So, my problems could possibly be related to driver bug in the addressing of system RAM above 3 GB, or latency in the handling of bus master memory requests on my nVidia nForce4 motherboard as noted in the Creative article referenced in my original post, some combination of the two, or something else entirely.
In the mean time, I'm soundless, since sound quits within 1-5 minutes, infrequently preceded by one or more very loud screeches.
Any ideas for temporary fixes/workarounds to restore undistorted sound? Otherwise I fear I will remain soundless until commercial release (hopefully containing fixed Creative and nVidia drivers)!
Thanks again for everyone's help.
I've reported my issues and system details on the Creative Bug List.
