1. AL_PITCH seems to work, but laststand is still a bit weird.
2. Panning somewhat works now.  Need someone to verify.
3. There is no EAX/Reverb.  But there's probably not much I can do...
4. Restarting sound system may or may not work.
5. Doppler (if it was originally used) isn't currently used.
6. Better Error Handling (device not avail, etc).
