not sure if I have correctly understand what you mean, after applying my 
patch you can specify:

- minimum-silence-buffers or minimum-silence-time before detect silence
- get notified on the bus when silence is detected/not detected
- retimestamp when silence is detected/removed

additionally you can specify the detection hysteresis too, this value is 
applyed before minimum-silence-buffers/minimum-silence-time

is the plugin detecting silence for non silence buffers? Can you please 
share an audio sample and indicate the pipeline you used, what you 
expect and what you get?

thanks
Nicola
