I've got a Pi 2 running Jessie, which I did a dist-upgrade on just yesterday (24 Feb 2017). So I'm running the latest stuff.
On it is installed Chromium 56.0.2924.84. I'd like to cast from this device to a Chromecast (firmware version 1.22.80438) that I bought a couple years ago. So far, no joy.
I can cast to my device from everything else in the house that I've tried: my iPhone 6, an Intel Linux box running 14.04, a Windows 10 laptop, an Android tablet. But Chromium on the Pi never even detects the Chromecast on the local network.
The Pi is connecting up to the network just fine - I can browse, view YouTube videos in the browser window, etc. But it just never detects the Chromecast at all.
Any suggestions on how I can get this to work? Thanks.
My WiFi connection is via Edimax USB dongle, if that matters...
