[Openal] Second Life and 1.9.563

[Tom Porter]

I believe the configuration I am using for SL allows everything to use  
OpenAL.  The only real issue is the different between the version  
releases of OpenAL Soft.  1.8.xxx works just fine for me and I can  
continue to use it.  Something changed in the 1.9.xxx release such  
that it only partially works for me now.  I am not actually allowing  
OpenAL to use the ALSA plugin for PulseAudio, but rather have OpenAL  
configured to use the PulseAudio back end, directly.  I can try other  
drivers, i.e. ALSA and see if that makes a different for the 1.9.xxx  
release, but I will probably just continue to use the 1.8.xxx release  
and stop there, since my system is completely set up to use Pulse.  If  
I get the time, I may get the source from various places between the  
releases and see if I can determine which changes caused this behavior.

Thanks,
Tom Porter
