            Bug ID: 93690
           Summary: module-echo-cancel: there is no need for a sink when
                    echo cancellation is disabled
           Product: PulseAudio
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: modules

echo cancellation module does many different processes including noise
cancellation, automatic gain control, and echo cancellation.

When echo cancellation process is disabled(through method options) there is no
need for a sink because other processes don't need it. Moreover, I don't know
if it's possible but in this situation it might be good to provide an option to
hide the original source.(It seems a bit confusing and a redundancy to have
both denoised and noisy sources visible. I think it would be a good option to
provide even if it won't be the default behavior.)

BTW, see this relevant bug: https://bugs.freedesktop.org/show_bug.cgi?id=83557
