Firefox audio doesn't change when headphones are plugged in

My Realtek audio device is set up to detect the microphone jack and to switch the audio to headphones when they are plugged in. This works for everything except for Firefox. Firefox doesn't realize that the default audio device has changed and still uses the speakers. If I restart Firefox, it detects the correct default audio device. However, I don't want to restart my Firefox every time I plug or unplug my headphones.

Searching has revealed that there is no way to manually change the audio device in Firefox. But is there any way for Firefox to detect the current default audio device upon change? Other applications switch mid-stream when I plug in my headphones.

Re: Firefox audio doesn't change when headphones are plugged in

Hello,

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).

(If you're using an added theme, switch to the Default theme.)

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the Restart with Add-ons Disabled... menu item:
FirefoxSafeMode

If Firefox is not running, you can start Firefox in Safe Mode as follows:

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
  • On Mac: Hold the option key while starting Firefox.
  • On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
    (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

Once you get the pop-up, just select "'Start in Safe Mode" Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Thank you.

Then it may be your Addon issue. Check the addons

I restarted with Add-ons disabled and it didn't fix it.
