Not easily, because it's a one-to-many relationship.

I.e. [receiver.getContributingSources](http://w3c.github.io/webrtc-pc/#dom-rtcrtpreceiver-getcontributingsources) returns a *sequence* of [RTCRtpContributingSource](http://w3c.github.io/webrtc-pc/#idl-def-rtcrtpcontributingsource)s, whereas [RTCRtpContributingSourceStats](https://w3c.github.io/webrtc-stats/#dom-rtcrtpcontributingsourcestats) covers *one* csrc. A one-to-many relationship. E.g. you'd do:
async function collectCsrcStats(receiver)
  const stats = await receiver.getStats();
  return [...stats.values()].filter(({type}) => type == "csrc");

As @na-g mentions, this works in Firefox (assuming you have a server that emits csrcs).
