Hi, I try to work barnard (but w/o uiterm package). When I call the VoiceToggle function. I got this exception. Do you have any idea why it occurs?

The error message indicates that Barnard.Stream is nil (i.e. hasn't been initialized with gumbleopenal.New(b.Client)). You can see where this is done: https://github.com/layeh/barnard/blob/master/client.go#L28

Ensure that you correct create the gumbleopenal stream.
