Default speaker settings do not work correctly in Firefox

Hello. Our organization is experiencing an issue where sound settings are not carrying over correctly to Firefox. Specifically, this is with speaker settings. In multiple calling platforms (tested in Genesys Cloud and Teams), we are not able to adjust the settings for the speaker that audio plays from. We can adjust the default microphone setting, but not the speaker setting. This is only occurring in Firefox (works fine in Edge and Chrome).

Additionally, we've tried adjusting the default audio settings by going to Windows > Sound settings > App volume and device preferences, and changing the settings specifically for Firefox on this page. This does not work. When we check Teams or Genesys Cloud, it seems like Firefox is just picking any default without a rhyme or reason.

Any assistance would be greatly appreciated.

Is this only with the enterprise ESR version (115) or also the latest 125 version?

Try changing media.setsinkid.enabled to true in about:config.

Thank you for your reply. We are on the latest version of 125 for laptops, and 124 for our VDI environment. Have already checked that and it was already set to true.

Teams! Not my favorite.

I had two or three tab crashes trying to load https://teams.microsoft.com/v2/.

In the Call interface, a lot of text was blanked in various places and changing between laptop speakers and headset seemed to have no effect.

I'm guess I'm stuck using the desktop app for now.

For our organization, the issue is really with Genesys Cloud. We only tested audio in Teams to verify that this issue was not specific to Genesys Cloud.

Are you able to change speakers with the audioff - audio device selector extension?

Visit about:support in the address bar and scroll down to "Output Devices" to see the available audio devices and which one is preferred.

Change the default by creating media.cubeb.output_device (String) in about:config and set the value to the name of the device you want (as per "Output Devices") then restart the browser.
