Comment(by markspieth):
I have just added 33 which uses freesound upmixing and no longer requires
the .asound devices.
To use set the device to
ALSA:surround51
output will always be in 5.1 in the format L R LS RS C LFE
initial testing shows that it sounds really good for 2ch upmixed videos
with good separation.
6ch audio is reordered so that it conforms with the output device format.
4ch audio currently not supported but mono is.
music and phone is handled with wider centre width and phasemode.
down side is that it depends on libfftw3f but mythmusic already uses this.
This can be changed later if desired to use fft lib from avcodec.
