I am familiar with Taylor's system. My main problem is that my media
server, kodi, does not allow you to redirect the audio output stream and
I therefore must delve into the arcana of alsa and the creation of
virtual soundcard with the loopback device since kodi allows you in
setup to select an alsa soundcard. I will test the Taylor filtering
system with VLC or mplayer where you can redirect the audio output
stream from the command line.

There's a mention there of the calf plugin for Jack which can do
crossovers which seem to work reasonably well on the new RaspberryPi
with a couple of decent USB soundcards if you compile it for multiple CPU's
Tom
I am looking for an all in one linux/alsa (ubuntu for now) media
solution. So far I am using kodi to -
1 - Watch TV (MythTV backend)
2 - Play video files
3 - Play music files
4 - Play CD's and DVD's
5 - Play commercial Blu Ray disks (MakeMKV + kodi makemkv plugin)
6 - Browse Internet (Firefox + Chromium + kodi advanced launcher
plugin)
7 - Steaming video from internet (Amazon Prime Instant Video + kodo
plugin for Amazon Prime)
The one thing I cannot do from within kodi yet is play my heritage
analog sources (turntable and open reel tape deck). I can play them
using ecasound and the line input of my Xonar D2 sound card.
Currently my audio output is sent (hdmi) to a surround sound preamp
(Emotiva UMC-200) and then to a 5.1 speaker system. I wish to replace
the preamp with appropriate software running on linux and my Xonar D2
sound card. The reason for this is twofold.
1 - The hdmi audio stream uses lossy compression for anything more
that two channel sound and I wish to avoid this.
2 - I wish to implement a bi-amplified electronic crossover for my
main speakers (the sound card has 7.1 channels so there are enough
channels for a 5.1 channel system with the bi-amplification) using
software and my sound card.
The two problems I have are -
1 - What appropriate software is there to implement the surround
sound preamp and electronic crossover (I would greatly prefer not to use
pulseaudio, only alsa and other existing linux applications).
2 - Kodi has no options to redirect the output audio stream so that
the surround sound preamp and electronic crossover would have to be
implemented as a virtual alsa sound card unless one of you can think of
another option.
Any suggestions and links would be greatly appreciated.
