Build - Leo 1.4 12/19/2013

During audio P2P call testing, I noticed that after successfully having a 2 1/2 audio call talking from B2G --> Desktop on the same wifi network, I was never able to get mic input to be captured on followup gUM audio uses after about 15 - 20 seconds. A restart of the phone doesn't work around the problem - it persists after a restart. It even persists upon flashing new gaia/gecko builds on top of a base image.

STR looks something like the following:

1. Request & grant gUM audio access in a browser tab
2. Talk for about a minute or two
3. Kill the browser process
4. Request gUM audio again
5. Talk for a minute

Result - You'll notice in about 15 seconds, the sound you make will no longer be heard.

Note - this is a blocker for testing audio P2P calls, as I can only successfully get one audio P2P call to work on a single device before I hit this bug.

I'll try to nail down clearer STR with a different phone.
Steps wanted - can someone dig into this to see if they can reproduce this with consistent STR on 1.4 using as a test page?

I think this is vendor image problem - it's only happening on the leo 1.1 base image with gaia/gecko on top, doesn't happen on Buri. Likely fixed when we get a new Leo base image.
