Only the first blob from ondataavailable event will contain file signature. The rest will not contain it, hence it is not playable. You need to concatenate the blobs into one big blob.

Quoting from bugzilla

My understanding of the spec is that this bug is invalid; i.e., individual blobs are not individually decodable in general; they must be concatenated to produce a usable resource. And that's what we implemented.
