[LAU] getting LFE channel to work with PulseAudio 5.1

Hi, Have beat my head against the wall long enough... I have AV Linux, Hammerfall DSP card, am using Ecasound with ladspa plugins for DSP crossover, Pianoteq piano model, and Jack to glue things together. I built 2 nice large subwoofers (4 ft3 each) with 12" SBAcoustics drivers. Just realized the other day that my 5.1 surround sound is missing the .1; the LFE channel. I want to get it to appear in my PulseAudio sink, map it in the my Ecasound logic, and split the LFE signal between the 2 subs. Since I use them for 20 to 80hz, maybe this will sometimes detract from accuracy of movie music, but still I at least want to learn how to do it and see how I like it. Problem is, no matter what I do with /etc/pulse/daemon.conf, default.pa etc. (setting channels=6, channel order, no LFE mixing, etc.), I can't seem to get the LFE channel to work. I've searched the Internet over and over, read everything I could find and tried setting things like the articles say, but still the LFE channel just won't show up. Alsamixer shows front, rear and center master volume controls only; no LFE. pulsevumeter, etc., show only 5 channels, nothing shows the LFE channel. Any idea what I'm doing wrong? Thanks!! John
