When enable-lfe-remixing is set, an LFE channel is present in the
resampler's destination channel map but not in the source channel map,
we insert a low-pass filter instead of just averaging the channels.
Other channels will get a high-pass filter

+
+                    if (a == PA_CHANNEL_POSITION_MONO && on_lfe(b) &&
!(r->flags & PA_RESAMPLER_NO_LFE))
+                        *lfe_filter_required = true;


do a == PA_CHANNEL_POSITION_MON when it is stereo ?
