[Pianod] libao settings testing

[Jimmy Pop]

Starting at pianod-137

I got the folowing to work using the alsa system

player.c changes

in function BarPlayerAACCb

#add definition of ao_option

ao_option *ao_options = NULL;

audioOutDriver = ao_driver_id("alsa");
                ao_append_option(&ao_options, "dev", "stereo3");

then later

if ((player->audioOutDevice = ao_open_live (audioOutDriver, &format,
ao_options)) == NULL) ..........


My asound.conf is as follows for reference

#/etc/asound.conf
pcm_slave.eightchannels {
        pcm "surround71:Device,0"            # or "hw:1,0" for the second
card
        channels 8
}
pcm.stereo1 {
        type plug
        slave.pcm {
                type dshare
                ipc_key 87882222
                slave eightchannels
                bindings [ 2 3 ]
        }
}
pcm.stereo2 {
        type plug
        slave.pcm {
                type dshare
                ipc_key 87882222
                slave eightchannels
                bindings [ 4 5 ]
        }
}
pcm.stereo3 {
        type plug
        slave.pcm {
                type dshare
                ipc_key 87882222
                slave eightchannels
                bindings [ 6 7 ]
        }
}
pcm.stereo4 {
        type plug
        slave.pcm {
                type dshare
                ipc_key 87882222
                slave eightchannels
                bindings [ 0 1 ]
        }
}



Though through this success, I am having choppy audio now, with a single
stream, or multiple streams with a RPI and this method,
but ao_default_driver_id() streams smoothly
