(Yes, my Linux is Ubuntu 14.04.5 LTS; there was no place to say that in the above form.)

Tested in chrome # 56.0.2924.87 and Canary #58.0.3026.0 on Ubuntu 14.04 and not able to reproduce the issue.Please find the screen shot for your reference.

@jpivarski: Could you please let me know if i have missed anything and if possible, Please create new profile without extension and apps.Re-check once and let us know the observation of the issue which would help us to triage the issue further.

Thanks in Advance.

I confirm that we're using exactly the same version number and build of Chrome from your screenshot, however, I never get the "vidyowebrtc.web.cern.ch wants to..." dialog box on the left. So I'll include extensive screenshots below.

First, I created a new profile with no extensions. (You can see that the name is "AlienHead" in the corner, from the icon.) Then I visited vidyowebrtc.web.cern.ch. Nothing pops up, but I found the microphone-blocking icon in the corner and clicked on it to raise the dialog box on the right (step1.png). I selected "Always allow" (step2.png) and clicked "Done."

Then I reload the page and see that the dialog is back to "Continue blocking microphone access" (step3.png). I can repeatedly set it to "Always allow" and reload, and each time it goes back to "Continue blocking."

If I check the microphone settings (step4.png), I see that vidyowebrtc.web.cern.ch is in the list of allowed sites. Chrome has apparently stored this setting, but it doesn't follow through when I visit the site.

Until I saw your screenshot, I had never noticed the dialog box on the left. If I click on "Secure" (step5.png), I see a list of permissions, from which I have chosen "Microphone" and "Camera," which prompted me to reload the page. After the reload, they're still listed as "Allow" on the left dialog box, but not on the right dialog box.

I wonder why my dialog boxes look different from yours. We are definitely using the same version number and build of Chrome.

Wow, that is clearly the same version number and it is clearly working for you in a way that doesn't for me. I never see the "Allow/Block" dialog box on the left, for instance.

Since it's not the executable, I checked the files in ~/.config/google-chrome for permissions issues. They're all owned by me.

I don't actually know how I'd install a different version of Chrome (I get it through Ubuntu's packages), much less isolate it in a way that wouldn't affect my working version.

Therefore, I think I'm going to have to give up on this for now. If I get any news that might be relevant, I'll post it here.

Thank you for providing more feedback. Adding requester "krajshree@chromium.org" to the cc list and removing "Needs-Feedback" label.

I think I noticed the key difference: in your video, the microphone-choice drop-down menu is set to "Default." Mine (see step1.png) is greyed-out as "None available."

Somehow, Chrome isn't picking up on the fact that my computer has a built-in microphone (other apps use it) and the radio button reverting to "block" rather than "allow" is arguably intentional. Where should I start looking to learn how to point chrome to my microphone (the CRAS device)?

Able to reproduce this issue on Win-7 and Win-10 using chrome reported version #56.0.2924.87 and latest canary #59.0.3035.0.

Issue is not seen in Linux-OS and Mac-OS.

This is a non-regression issue as it is observed from M35 old builds. 

Hence, marking it as untriaged to get more inputs from dev team.

Thanks...!!

Harald: is your team owning the permissions pieces? Can you assign this to someone to look at?

This is a UI bug that happens when there are no microphones or cameras. The issue appears to be fixed in M58.
