Disabling Chrome Flags via Command Line: Not Working

Question

Our cloud contact center platform is being negatively impacted by the chromium flag "allow webrtc to adjust the input volume." (

Manually disabling it works, but we have ~550 users and I think that browser updates reset the flag.

I've been trying to create a shortcut that launches the browser via the command line, but it's not working. It does relaunch the browser, but the flags are left at default.

Here are the versions I've tried: (on edge as well)

1. From a helpful person here:

"C:\Program Files\Google\Chrome\Application\chrome.exe" --restart --disable-features=WebRtcAllowInputVolumeAdjustment

2. From the google issue tracker https://issuetracker.google.com/issues/398550914

"C:\Program Files\Google\Chrome\Application\chrome.exe" --restart --flag-switches-begin --disable-features=WebRtcAllowInputVolumeAdjustment --flag-switches-end

3. Based on the Chrome://versions/ after manually disabling the flag

"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=WebRtcAllowInputVolumeAdjustment --restart --restart --flag-switches-begin --flag-switches-end
C:\Users\10023999>"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=WebRtcAllowInputVolumeAdjustment --restart --restart
C:\Users\10023999>"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=WebRtcAllowInputVolumeAdjustment

**Both the Chrome://versions and the Flags page confirm that it is still at default, not disabled (as expected).

Anyone have a better CL prompt I should use? Or have an alternate solution?

Thanks!**

As noted in the bug, if automatic gain control, which is generally considered to be a good thing, is not for your environment, then making sure your javascript code calls the getUserMedia API disabling it is the way to go:

const stream = await navigator.mediaDevices.getUserMedia({audio: {autoGainControl: false}});
