With the upcoming changes to WebRtcVoiceEngine due to injectable audio encoders, codec names will no longer be normalized against the ACM's codec database. This not only breaks a couple of downstream tests (which I've written fixes for) but also runs the risk of breaking other external usage, like SDP mangling etc. Eventually, we should change to using the spelling from the relevant RFCs, although not as part of this other, large change.
