and i can confirm that it is playing both channels (all frequencies - not only low)
same happens with enable-lfe-remixing = no (command commented out) but during playback i change to analog-stereo-duplex pulse audio profile and then again to 2.1 - all freqs from subwoofer can be heard
so
it is good that it mix 0.5 of left and 0.5 of right (and not only right) but it should take only low freqs - is there a way to make it happen?
this log is with lfe-remixing = yes enabled in pulse
