There is probably little need to have this error message, given that's in the callback already.
Same below and in later patches.

I used the `wb_` prefix for "WaveBank" because I expected to use different locks and RB trees for different object types. Since you are using the same lock and tree for all object types (which is probably more sensible), maybe the prefix could be removed.

The `wb_` prefix can be removed. It standed for "WaveBank", but it's more sensible to use the same lock and RB tree for all object types as you are doing.

Is this magic constant a good idea? Unfortunately we don't have a maximum constant for the notification types, but I'd rather go with `XACTNOTIFICATIONTYPE_MAX` and tolerate the wasted memory than leave a magic constant.

Or we could just define our own constant.

This and similar accesses are undefined behavior when the caller requests an invalid notification type, and it doesn't seem we have any protection against that. What does happen on Windows when an invalid notification type is requested?

Does it make sense to store this pointer? We're unregistering notifications, so we don't expect this context to be used anymore (until the next `RegisterNotification()` call, but then a new pointer will be given). Does the caller have any visibility into the pointer stored here?

Thinking better, it might be the case that the pointer passed here is somewhat visible to the caller, given that the XACT notification system is quite convoluted and notifications can be registered and unregistered for individual objects. It wouldn't be bad to have some tests showing this behaviour on Windows, though.
