On the prior version of Chromium the Chromecast extension could find my Google Chromecast v2 devices. Now it can't and it says it can not find any devices when I try to cast. What's going on and how to I fix it?

Works at least with Version 55.0 (the version shipped with 16.10).

So there are two ways to cast to Chromecast

  • one of them is with the extension
  • the other one is with the native functionality.

This should work natively with Google Chrome.

I do not believe Chromium supports the native cast. Disabling this native feature opens up the ability to use the extension. Or you can use Google Chrome.

  1. Open up chrome://flags/#media-router, it should say Media Router Mac, Windows, Linux, Chrome OS: Enables Chrome to access external presentation-type displays and use them for presenting web content. #media-router
  2. Change it from Default to Disabled
  3. Restart chromium-browser
  4. Install Google Cast extension if necessary

This should work. There is a Launchpad bug opened here. The answer is based off Bob Smith's suggestion on this Debian bug. You can now see this advice in the official faq How to turn off Media Router and use the Google Cast extension.

    This apparently doesn't work as of at least yesterday (Jan 24th, 2017): https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1621753/comments/6 – Victor Jan 25 '17 at 18:26
  • Still working for me. – Evan Carroll Jan 25 '17 at 18:31
  • Well, it's not working for me, @EvanCarroll. You probably just haven't updated and restarted your browser yet. – Victor Jan 27 '17 at 20:21
  • K bruh, *Version 55.0.2883.87 Built on Ubuntu , running on Ubuntu 16.10 (64-bit)* – Evan Carroll Jan 27 '17 at 20:23
  • @EvanCarroll Version 57.0.2950.4 Ubuntu 16.04 (64-bit) can confirm I dont even have that flag anymore, work laptop with same version as yours does still work though – Max Ehrlich Jan 29 '17 at 15:36
  • I can confirm that with Chromium 56.0.2924.76, it doesn't work even with the workaround. In fact, the specific "switch" to turn off in the media-router settings no longer exists. Chrome still works though. – Pepe Lebuntu Mar 04 '17 at 09:08

    Google won't let me installed [the chromecast extension](https://chrome.google.com/webstore/detail/google-cast/boadgeojelhgndaghljhdicfkmllpafd) anymore, with either the media router flag disabled or default. Any idea if using chromecast is still an option? – ThorSummoner Apr 01 '17 at 22:58
  • Not working here on Papa Debian either. 57.0.2987.98 built on Debian 9.0, running on Debian 9.0 (64-bit) – RichieHH Apr 14 '17 at 16:41

I am using chromium Version 57.0.2987.98, Ubuntu 17.04 (64-bit). The native "Cast..." does not work until you enable this flag below. Once its enabled, it works perfect, no need for any extension.

chrome://flags/#load-media-router-component-extension

  • yep, works for me on debian 8.7 with chromium 57.0.2987.98. The other answer said to *disable*, but i found that only *enabling* the property you list works. – mulllhausen May 21 '17 at 10:42
  • Ubuntu 16.04 LTS with Chromium 58.0.3029.110 confirmed solution. – s3m3n Jun 13 '17 at 14:11
  • This also works for me on Gentoo and Chromium 59.0.3071.104. I'd note that I had to change the setting from "Default" to "Enabled" and restart the browser. – David Z Sep 13 '17 at 05:44
  • Confirmed on Slackware64-14.2 and Chromium Version 62.0.3202.75 (Developer Build) (64-bit). This appears to be the correct answer as of February 2018. – YellowApple Feb 21 '18 at 01:28
  • I also had to enable `#media-router-cast-allow-all-ips` for my Chromium 74.0.3729.131 to work. – Waldir Leoncio May 13 '19 at 19:39
  • Is there an upstream bug for this? It seems incredible to have such a large feature completely non-functional, with no user-visible messaging that it is non-functional, by default. – Thanatos Aug 19 '19 at 06:06
