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.
