Improve error handling and revert old debugging code.

This pulls out some of the extra debugging code I've added for the
debug builds I've been handing out.  Specifically:
- Checks error status on Start() and Stop().
- Ensures preconfigured AudioBus channel count matches
buffer list count.
- Removes old debugging code that is never triggered.
