[Openal] Frequency & Pitch Shifter attribute bounds..

[Dan Peacock]

Hi Alex,

What soundcard are you using, and does it have up-to-date drivers
installed?   If I run EFX10Show (included in the Windows OpenAL SDK) I
can set the full range of parameters for all the effect parameters you
mentioned here.  I also ran some further tests and didn't see any
problems with effect parameter ranges.

Dan
