Description of problem:
I have observed this problem with scorched3d.  Bug 203336 indicates that it also
affects TORCS.  Until the last openal update, scorched3d worked fine on my
system, an x86_64 platform with an on-motherboard ICH7 sound system.  Now
scorched3d cannot be played with the sound turned on.  It will run for a short
time, typically less than a minute, then crash.  When it crashes, this is the
backtrace:

(gdb) bt
#0  _alFloatMul (bpt=0x1e3cff8, sa=Variable "sa" is not available.
) at arch/i386/x86_floatmul.c:88

#7  0x0000003bb3dcc38d in ?? () from /lib64/libc.so.6
#8  0x0000000000000000 in ?? ()

This only happens on the x86_64 platform.  I have a 32-bit x86 platform where it
works fine.

Version-Release number of selected component (if applicable):
openal-0.0.9-0.6.20060204cvs.fc5

How reproducible:
Always

Steps to Reproduce:
1. Start scorched3d on an x86_64 machine.
2. Make sure that sound is turned on.
3. Play, typically for less than one minute.
  
Actual results:
Scorched3d crashes, regardless of video settings.

Expected results:
Scorched3d should continue playing normally.
