Pi zero W sound

[archiver]

Hello, I am making a project, the adafruit super pi boy and have now problems with audio. I am using a pi zero w instead of a normal pi and have therefore no audio jack. I still intend to use the class d audio amp (TPA2016D2).
I want to connect it directly to the gpio pins.

Please advice

this seems to work only for video, not sound

@jonnykesh right! But that's the video part!
@archiver I would advice a I2S amplifier or an exteranl USB sound card. Why? The analog output isn't good - you will have cracks and pops.

EDIT:
But @jonnykesh is on the right way. The GPIOs provide analog output!
Here is how to do! https://www.raspberrypi.org/forums/viewtopic.php?t=127585

wouldn't this one work somehow?

@archiver That's just an amplifier!
You've to restore the analog signal for this!

Me and @jonnykesh showed you three ways. Choose one - you are a free man.

my retropie instalation keeps resetting volume to 0... how do i prevent this?

[archiver]

failed to find mixer elements keeps popping up on terminal...

Also, can I use only my amplifier or do I have to copy everything exactly?

EDIT: I somehow got the audio to work via gpio, albeit with crackling... now to fix this
