Hello guys, I’m currently working on my ESP32-MP3-Player, and need to design the DAC correctly for Headphones.
heres a pic of the placement:
Hope anyone can help me! (and don’t think I’m a bot!)
And we know what you’re hoping for, but we don’t know what you’re asking.

It looks like you already have a GND plane, possibly even on two layers. This was not visible in the screenshots in your other thread. I guess that the PCB outline on the Edge.Cuts layer is still missing.
For the circuit design around the PCM5102A DAC, have a look at application notes, and/or schematics others have posted on the internet. I am missing an decoupling capacitor, but as this is partly analog, I assume more parts should be added too. You could consider rotating the IC. This probably improves the routing a bit.
But overall, this forum is for questions about KiCad, and not about circuit design. There are better sites for that, such as eevblog.com, or DIYaudio.com.
Layout in the context of KiCad . . .
I find it hard to believe your question is about routing those two tracks.
If I look at the datasheet of that IC:
… then I see:
Note that this is a Simplified Schematic, and thus it’s not complete. You are missing quite a lot of stuff here.
I was that far too! but whats the GND for the Speakers/Headphones? And how do i create a low-pass filter for that?
That isn’t a KiCad question . . .
but a question for the Layout category! no joke, it comes across as if you are just complaining! and that really annoys me!

You are clearly a novice in electronics design. We (unpaid volunteers) can’t spend our time and resources teaching non-KiCad related basics to people. As was said, the forum is for discussion, questions and answers about KiCad. Occasional off-topic posts and digressions are allowed to some degree, but only to “some” degree. You have to find another place to learn electronics design.
