Playback Issues on Dell Laptop with MaxxAudio Pro
A Dell laptop may not play audio on the internal speakers and/or headphones. Additionally, the MaxxAudio app may show a blank screen, or show an error about the audio drivers being out of date.
One cause for this can be corrupt or invalid registry information for MaxxAudio Pro. To remedy:
- Open an elevated command prompt.
net stop WavesSysSvc /y
reg delete "HKCU\SOFTWARE\Waves Audio" /f
reg delete "HKLM\SOFTWARE\Waves Audio" /f
We also found that upgrading from Windows 10 to Windows 11 resolved some issues with playback via different outputs.
