It may work on other Dell laptops that ship with Waves MaxxAudio if you are aware of models where this driver works, please post to /r/dell and submit a pull request so I can update the guide. I'm running it on the latest Dell with success. This is confirmed to work on Dell XPS 13 93XX and Dell XPS 9550/9560. Luckily, a user has created a copy of the Dell Realtek drivers without Waves MaxxAudio, which removes post-PROCESSING and the GUI pop-up. Waves MaxxAudio is known to push audio beyond acceptable volumes, which can cause physical speaker damage to your laptop.Using the Generic Microsoft High Definition Audio drivers will produce crackling and popping under certain conditions.Instructing the software not to ask again is inconsistent and will often be reset on reboot. Connecting a device to the headphone jack will nag you with a pop-up asking you to pick what device you just plugged in (headphone, headset or microphone).Even with all effects disabled, post-processing still occurs.The Waves MaxxAudio software, which is part of the Dell Realtek drivers and is packaged with the Dell factory image causes numerous problems: Changes or additions are welcome in the form of pull requests. Enhancements have been exclusively tested on a Dell XPS 13 9370, and should work on other configurations unless otherwise noted. This is a comprehensive list of enhancements that aim to create the optimal Dell XPS 13/15 experience.
