Looking at our implementation, there are only 3 cases where we may throw a NotSupportedError:
- Sample rate of the buffer does not match sample rate of the audio context
- Buffer does not have 1, 2 or 4 channels
- Buffer has zero size

In WebKit trunk, the exception message would actually give you a proper exception message so you'd know which one is the issue. Sadly, this change is not present in the latest STP yet.
