mActive is protected by mLock; volatile is meaningless on SMP.
Fixed a couple of places where mActive was accessed without a lock:
- stopped()
- processAudioBuffer()
Added stopped_l() for cases where we already hold the lock.
Made mActive a bool not int.
Moved down a lock in setPosition that was being acquired too early.
