So you know when you click Airplay option, it is supposed to show Sonos if your mac and sonos are on the SAME wifi.
After setting up the wifi for my Sonos (Play5) through my Android app, I open my laptop. I keep switching b/w my two Wifi (same name, but one 2.4 and the other 5). Sometimes, really sometimes then Sonos shows up. However, most of the cases, I need to unplug Sonos from power for a sec, and reboot, then Sonos shows up on my Airplay list.
Any idea how to trouble shoot this?
