<pre>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: <a class="bz_bug_link
