After last update no longer network upnp dac over audirvana

[Wolfman74]

It will be fixed in the next update from Volumio

Audirvana Studio no longer sees VOLUMIO 3 since update 3.198

We got some reports that Volumio appeared as a duplicate entry in Many UPNP clients. So we disabled UPNP\AV Discovery. This seems to have broken Mconnect and some other UPNP clients. But it’s fine here with Bubble UPNP. Anyway, fix is underway (we will revert the previous fix)
