This. I recently had to buy a small 15€ USB sound card because, as it turns out, my new Dell laptop's built-in audio card doesn't work properly on Linux(×). Not only is the sound orders of magnitude better, it also comes with a handy volume knob! It's so much fun to use!

(×) I can't believe it's 2020 and I'm writing this. I haven't had any significant hardware issues on Linux in almost a decade. What's even worse is that Dell specifically claims that the laptop is fully compatible with Ubuntu.
