What steps will reproduce the problem?
1. Start a loopback test with any L16 codec
2. enable FEC on that channel
3.

What is the expected output? What do you see instead?
The audio should be normal. But instead you can hear some intermittent noise(kind of bubble effect).

Please use labels and text to provide additional information.
There is no such noise when testing other codec+FEC or no FEC with L16.
Tested with newest webrtc on Win/Linux

Hi Turaj,

Could you continue to follow up this issue? Set to low priority though.

This is a really old thread.

@braveyao, is this still valid? What FEC did you mention from the beginning?
Project Member Comment 6 by braveyao@webrtc.org, Feb 25 2015
The FEC mentioned here is the FEC set with API VoECodecImpl::SetFECStatus(), which used to set FEC to all the codecs. 
I see that in latest trunk, now only the codec which has internal FEC could be enabled by this API, otherwise it would return failure. So there is no way to enable FEC to L16 any more. Is this design of new ACM? If so, then I suppose this issue could be closed.
