STRs: 1. Use a headset 1. Open https://jsfiddle.net/jib1/cknfm2tL/ in two different tabs. 2. In first tab, click the [Call] button and share cam + mic. Expected result: - When speaking, you hear yourself fine in headset. Actual result: - Raspy distorted voice with static noise and a one second delay.

I found this trying to reproduce bug 1405893. There's a chance they're the same, though the symptoms here are instant.
Note that a headset is not required to reproduce, it just makes the problem stand out more.
According to Alex the patch for bug 1406027 seems to help. If that's the case I would have expected this to be regression from a combination of bug 1319445 and bug 1243857 (for mac), or more recently, bug 1330360. In any case, not bug 971528. Similar to bug 1381638 but I think bug 1406027 fixes the root cause of those distortions.
Regression bug is wrong I'll find a new regression range. Patch from bug 1406027 solves the problem.

I just redid the regression range and I still get the range in comment 0!
Note I have a new 2016 MBP with stereo mic. Might that explain why I'm seeing a different regression range from Alex and Andreas?
too late for 56, and probably not worth tracking for 57.

jib, since you had a different regression range, could you verify that this works in latest nightly?
