</span>Can you confirm that the streams were actually connected to those<br>
devices? Look at the output of pactl list sink-inputs and pactl list<br>

</span>You can't configure this via the environment. With filter.want, the<br>
default which is compiled in is used (webrtc if we have it, else speex).<br>
You can only control this if you manually load the module as you ahve<br>
above.<br>
