Example configuration of a duplex sink/source

context.modules = [
{   name = libpipewire-module-ffado-driver
    args = {
        #driver.mode       = duplex
        #ffado.devices     = [ "hw:0" ]
        #ffado.period-size = 1024
        #ffado.period-num  = 3
        #ffado.sample-rate = 48000
        #ffado.slave-mode  = false
        #ffado.snoop-mode  = false
        #ffado.verbose     = 0
        #latency.internal.input  = 0
        #latency.internal.output = 0
        #audio.position    = [ FL FR ]
        source.props = {
            # extra sink properties
        }
        sink.props = {
            # extra sink properties
        }
    }
}
