ssdp discovery fails with IPV6 addrs
ssdpUnicastDiscoverImpl & ssdpMulticastDiscoverImpl depend on IPV4 address but don't ensure IPV4 addresses are used.
The code currently grabs the first entry returned by net.Interface.Addrs() and on my machine the following is returned:
Addr[0] = fe80::72cd:60ff:fef3:75ad/64
Addr[1] = 192.168.1.68/24
Since the first entry is an IPV6 entry the code issues a panic and fails to complete discovery.
Cannot find devices
I am trying to identify sono devices on my network.
But I am getting an error.

Hi,
I have been trying to workout how to use the library in its current form. Could you give a brief description please?

Locking up during discovery
Heya just trying out this library and it seems to freezing during discovery for some reason.
Anyone else had this issue?
I have this line in my code but it never returns.
unit := sonos.Connect(player, reactor, sonos.SVC_CONTENT_DIRECTORY|sonos.SVC_AV_TRANSPORT|sonos.SVC_RENDERING_CONTROL)Panic while handling reactor event
With this code:
{
exit_chan := make(chan bool)
reactor := sonos.MakeReactor(SONOS_IFNAME, SONOS_EVENTING_PORT)
go handleSonosEvent(reactor, exit_chan)
}
func handleSonosEvent(reactor upnp.Reactor, c chan bool) {
for {
select {
case evt := <-reactor.Channel():
switch evt.Type() {
case upnp.AVTransport_EventType:
log.Printf("Got Event!")
}
}
}
}
This exception is thrown:
panic: reflect.Value.Interface: cannot return value obtained from unexported field or method

If I comment out:
xml.Unmarshal([]byte(doc.LastChange), &this.AVTransportState.LastChange)
upnp/AVTransport.go line 132, the code continues. I'm not familiar enough with golang to understand fully what's going on here.
