[BA] Can you take a shot at posting text to the list?

Other than some typos, the only other remaining question is determining exactly what dictionary entries are updated when a packet with CSRCs, the mixer-client extension but no client-mixer extension is received. 

In this case, are just the CSRC audio level entries updated, or is the SSRC audio level entry also to be computed per RFC 6464 (although it is not actually present)?
