I got a crash when using intel cs for webrtc 4.3.1 windows sdk on my computer(win10 system run on mac book with Boot Camp): reproduce steps:

1. just run P2PSampleMFC sample

2. connect to peer server

3. click publish

abort() has been called

it seems that 4 channel playback device is not supported in this win sdk and no fallback solution is implemented in win sdk;

with some investigation in the wbrtc79 , I found 4 channel playback is not supported  in  AudioDeviceWindowsCore class

Hi

Have you fixed this problem later?

I meet it too.
