[Sumover-dev] RAT and linux 64b

This doesn't look good, the memory seems corrupted, it should be 
outputting something like:

[pid/4110 +1177 auddev_alsa.c] ALSA version identifier == Advanced Linux 
Sound Architecture Driver Version 1.0.16rc2 (Thu Jan 31 16:40:16 2008 UTC).

I think when I used to build RAT on x86-64 Fedora Core 3 (which RHEL 4 
is based on), I used to disable building the ALSA support because I had 
all sorts of issues with ALSA. For Fedora Core 4 and later I would build 
the ALSA support. To disable building the ALSA support I think I used to 
patch the configure script to avoid detecting ALSA or something.

I don't know, if RAT doesn't work I would be pointing the finger at ALSA 
as the likely candidate for the failure.


Cheers,
Doug
