I am similarly affected by this issue, we have a large number of Chromecasts on our network, v1 and v2 and whilst the previous version of Chromium worked just fine with the plugin installed this new version is broken in some regard.
google-chrome-stable 53.0.2785.101-1 package does work, however. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1621753 Title: Google Cast no longer finds Chromecast device Status in chromium-browser package in Ubuntu: Confirmed Bug description: After upgrading to latest chromium-browser version (52.0.2743.116-0ubuntu0.16.04.1.1250), the Google Cast extension no longer finds the Chromecast (v2) device.
