* Looping sounds that have been playing for a very long time, were evicted,
and then were restarted need to have their positions clamped to lie
within the bounds of the sounds. If we try to set a start position very
far beyond the end, it will overflow inside FMOD and not work.
* A start time of 0 is not actually valid and means the sound was never
assigned a start time.
- The latter bug also reveals a problem with starting looped sounds evicted:
They need to be assigned a start time so if they should have the opportunity
to start later, they will be properly synchronized.
