No, I mean that capture is possible only when mute=off and capture=on.
As far as I can understand this must be a bug. For example, if you
want to do real-time audio processing, you want to send the input
signal to an audio processing application without sending it also
straight to the output. And I think that's how it used to work on
older sound cards I have owned.
