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
