I don't think that is true, it is still PWM audio driven by the CPU, there is no audio processor the only thing is there is more CPU power available to drive the PWM audio with less stutters but it's still lower quality than a DAC, other than that the Pi3 is good if you want to play N64 or PSX

Yes this is why I put "real" in quotes. I meant to say that you already have a dedicated audio port out of the box instead of having to solder wires to the PWM out of a Pi zero and changing configuration accordingly. ;) Yes, I admit, it is an easy thing to do, but the fact still is that you don't need to on a Pi 3. :)
Ladies and gentlemen, I would like to inform you that I am currently moving very far away, and therefore I am very busy.

UPDATE: I am still alive! My ISP is setting up my internet on the 19th of January at my new place, explaining my offline-ness.

If you write me a PM, I will very likely take some time to respond.

Also, my 2nd build will soon go on, so if you've been following it, please stay tuned! :)

Many thanks for your understanding!

Nice :) Sorry I'm pedantic it just implied differently to me but you're right!

It's all good ;)
If I think about it, I should have been more specific in the first place :)

Then next up was audio. :) I soldered wires in all possible ways to my amp only to hear terrible static noise/bad sound quality in every constelation I have tried, untill my friend thaught me about pickup noises, static pickup etc. and I sucessfully removed all static by keeping wires short, doing proper grounding, laying wires differently, so they won't interfere etc.

Long story short, it took me a long time to have it working perfectly, but at least it is perfect now. :D

Is there any chance you could elaborate on how you solved this? Audio noise is my biggest hurdle at the moment.

Which pads did you use for audio? I'm using a Pi 2 and am having heaps of audio problems.

Thanks!
