Dell laptops, ruining audio drivers in 2023

This is a "rant + fix" blog post. If you're looking for an interesting post, check out the other ones.

I own a Dell Latitude 3420. It works well, has good battery life, good keyboard, and lots of connectors (laptops today, ugh). I got the 1366x768 version though, so I bought a replacement 1080p display because 768p is... small.


From the beginning, there was a process constantly hogging up the CPU, idling at 25-30% usage, all the time. AC or battery, High Performance or High Efficiency mode, it was there. "WavesSysSvc":

I looked around and found that it was part of the audio driver. Why the hell would my audio driver take up a third of my computing power?!

Additionally, the headphone jack would just... refuse to work. The only way to get it to work was to have my headphones/speakers plugged in when the computer started, but that's not viable, so for all intents and purposes it was broken.

I searched, browsed the Dell forums, saw that a lot of people were having that same problem, with no answer from Dell apart from "try updating your drivers using SupportAssist" (my drivers were up to date).

Then, stumbled onto

GPT: Straight Outta Copilot

I'm not a lawyer.

You may have heard about this thing called GitHub Copilot. It's a tool that can be integrated inside an IDE and allows you to rip off code from licensed code hosted on GitHub. It has no intelligence of its own whatsoever, and any code is spits out must have been written as-is by a human developer at some point.

Oh, wait, sorry. That was Copilot writing a blog post from the perspective of someone that doesn't like it:

There have been lots of good and bad takes on Copilot these last months, since the release of its technical preview in June of 2021 and its general availability in June of 2022 on a subscription basis.

The recurring themes are, mostly:

  • Copilot is a copyright violation machine, since its dataset comes from code written by humans (i.e. intellectual property), and code produced by Copilot should constitute a derivative work.
  • Copilot is bad for education, because it offers no guarantee of the correctness of the code written. In the hands of beginners, it can give a false illusion of competency.
  • Copilot is bad for security, because it's just making the same security mistakes that were present in
