They are, but IIRC the exact attenuation behaviour can be defined for

I don't know for sure - but perhaps OpenAL is keeping some volume
"in reserve" for when multiple sounds are playing together.
Also, aren't OpenAL's sounds range-attenuated? Can you move your
virtual 'ear' closer to the sound source?
In fact, Creative Labs ships an own binary OpenAL.dll with it's Windows
drivers for its newer sound cards. And nVidia has an own OpenAL
implementation for its nForce chipsets, too. The open source Loki
implementation is still maintained. UT2003, for example, heavily relies
on OpenAL (both on Windows and on Linux IIRC). So OpenAL will stay
around for quite a while. I even believe that its will spread a lot in
the nearer future. Maybe Doom 3 will have OpenAL support, too? ;)

I sure hope it's here to stay. It's OpenSourced - so in a sense,
it'll never "go away" - but OTOH, it's biggest proponent (and
contributor) was Loki - and they are long-gone. However, it's
also backed by Creative Labs - and they appear to be going strong.
