I can’t enable Waves MaxxAudio Pro: the button is grayed-out and I’m unable to toggle it on. How can I fix this?

Verify that both MaxxAudio Pro and the Realtek audio driver are up to date with the latest version available on the Dell website.
Please note: older versions of MaxxAudio Pro (computer models purchased prior to 2019 and using version 1.xx) support internal speakers and external devices connected via analog audio jack only. MaxxAudio Pro will not be available . If you are using a Bluetooth or USB audio device, as these devices are not supported.
