The control app thread

[simoncn]

This mention of IGMP made me curious to try this myself to see what happens. My network is fully set up to correctly handle IGMP queries (i.e., IGMP snooping is enabled and configured to work correctly). I started the LUMIN app on my iPad and a Linn renderer, played some music and then cleared the playlist. After 55 minutes, the LUMIN app was still seeing the Linn renderer. After another 30 minutes, the Linn renderer was no longer visible. Restarting the Linn renderer made it visble again in the LUMIN app.

I think this means the LUMIN app bug is not caused by issues with IGMP snooping, unlike many other similar problems that have been discussed on this forum.
