Fix WebRtcAudioDebugRecordingsBrowserTest.

https://chromium.googlesource.com/chromium/src/+/086a4113b499025bdd7db2c19a10bd8cd34a5997 broke https://build.chromium.org/p/chromium.webrtc/builders/Win10%20Tester/

(Only that particular Win 10 bot.)

The short-term fix to get the bot green is to revert to not check expectations of return value when deleting files.

Long-term it should be investigated why this happens. Perhaps explicitly disabling would avoid the issue.

OK, it's all Win bots in the WebRTC/Chromium waterfall. Maybe this test isn't run in the ordinary Chromium waterfall? Bots should go green now anyway.

Fix WebRtcAudioDebugRecordingsBrowserTest (part 2).

Explicitly disable audio debug recordings in its browser test.

This could perhaps fix one or both of the bugs. Regardless, this is a reasonable change to do anyway.

This also fails on Mac, see https://build.chromium.org/p/chromium.webrtc/builders/Mac%20Tester/builds/65966/steps/content_browsertests/logs/stdio.

Re comment #5: that's another failure, tracked in issue 700859.

I could repro this locally. I noticed that after ExecuteJavascriptAndWaitForOK(), the call is still running, hence files can't be deleted since already open.

In my local test environment, the explicit disable added in revision 456667 closes the input and output files, but not the AEC dump file, in time. The AEC dump is in the render process so it takes longer before getting there. However, all files are subject of timing when closing.

If navigating away (to same url) after disabling, I can't repro.

Edward: Is there a function to stop a call? I couldn't find that looking in peerconnection-call.html.

Doesn't look like there is.
I think you could do something like the hangup() function in https://github.com/webrtc/samples/blob/gh-pages/src/content/peerconnection/constraints/js/main.js

Hangup call in WebRtcAudioDebugRecordingsBrowserTest.

This ensures files are released and can be deleted, thus re-adding expectations on file delete success.

Added hangup() function to peerconnection-call.html.

I'll wait for the bots to run this before closing.

Looking good.
