Error caused by Voice Engine

[qiaotian]

I configure peerconnection server on Ubuntu 16.04 server VM, which doesn't have voice device. It seems works. But when I click the green icon on web page to create connection, an error shows as follows:

Any code contains 'voice' had already been removed. I have no ideo what is wrong behind. Any clue will be appreciated!

Did you find any solution to this ? I also removed parts about audio but still it crashes
