Problem statement:

Chrome suddenly stopped doing stereo output the other day...

Solution

It turns out we were never actually modifying the SDP string because the return values for replace were being thrown away instead of being applied to mungedSDP which had itself been declared const for some reason anyway.

Test Plan and Compatibility

I simply recompiled and checked out the infra in Chrome, noting that stereo has indeed returned. For good measure, I also checked the applied SDP configuration, noting that it now actually reflects the changes we wanted.
