Hi!I have looked the wiki, tried lot of stuff, asked to some LUG list and since nothing else worked, I fall back on youI don't understand clearly how alsa is working...I started with http://www.alsa-project.org/main/index.php/Asoundrc
my need :I have a 5.1 ogg stream, and a 5.1 soundcard, but I just use the 2.0 one (I don't have 5.1 speaker system, just headphones)sadely ogg don't merge the streams as aac lib does to make a 2.0 sound from a 5.1 one, so when I listen to this stream I just hear partial sound...
so what I need is  - a way to create a virtual 5.1 alsa device that merge all streams into a 2.0 one  - the device shall accept multiple client (like dmix)
I thought first at usingPlugin: Route & Volumebut it don't allow multiple clientI then tried dmix, but the binding field don't seems to work correctly
I tried with
bindings {      0 0 # map front left to left      1 0 # map front center to left      1 1 # map front center to right      2 1 # map front right to right      3 0 # map rear left to left      4 1 # map rear right to right      5 0 # map subwoofer to right      5 1 # map subwooder to left}
as a first approximation.... but well didn't worked correctlycan someone help me?thanksJLM
