[pulseaudio-discuss] how combine two steoro source into one source?

[陈士伟]

Hi All:

I'm studying pulseaudio now, I get a problem, How can I combine two steoro 
source into one source?
just like in alsa, I can use virtual muti device, the configure as below:
pcm.quad {
        type multi
        slaves.a.pcm "hw:2,0"
        slaves.a.channels 2
        slaves.b.pcm "hw:3,0"
        slaves.b.channels 2

        bindings.0.slave a
        bindings.0.channel 0
        bindings.1.slave a
        bindings.1.channel 1
        bindings.2.slave b
        bindings.2.channel 0
        bindings.3.slave b
        bindings.3.channel 1
}

pcm.quad2 {                
        type route         
        slave.pcm "quad"    
        ttable.0.0 1       
        ttable.1.1 1       
        ttable.2.2 1       
        ttable.3.3 1  

}

Thanks very much!
