HIFI Cast / avahi / openwrt / chromecast 'Speaker Group'

[pluffmud]

First I'd like to say I dont believe this is an issue with HIFI Cast  , just looking for info .

My router is running openwrt with avahi installed . I have 2 vlans 1 and 3 with 3 chromecasts on vlan 3 .

With avahi running and a firewall rule in place HIFI Cast on my  Android on vlan 1 is able to discover the chromecasts on vlan 3 with no problem .

What it does not do is discover a "Speaker Group' I created .

If I move the phone to vlan 3 it discovers everything .

Whats also odd is that  the chrome browser on my Linux box can discover the 'Speaker Group' from vlan 1 .

So my question is what is different about the 'Speaker Group' discovery ?

I suspect there is something lacking in my avahi setup or in the firewall .

Hi,

From an app developer's perspective there's nothing different between discovery of a single chromecast or a group. I had always assumed this meant that the underlying mechanism was exactly the same - but I guess its possible the Android SDK is handling any differences and presenting a single API for the app developers.
