Is the audio filter necessary?

[SamuraiCoder]

Hi guys,

Totally beginner building the gbzero. I´m in the part I´m building the audio part. I have the adafruit 2.5w amp connected to the jack, power and two cables. I don´t know where that two cables go.

I saw Wermy built an amplifier. Is there any recomendation AIO to get this one? or any webpage in europe I can get the components? I bought GameBoy Zero PWM Audio Bufffer but it comes "empty" and the Merlin04 board but I need components for that.

Cheers.

I couldn't tell a difference with or without it in my builds. I'd say try without, if you're not happy with the quality, then add one.

As for a beginner I'd recommend waiting for an AIO to come available.

Good luck.

So then, connect the two wires on the amp to the rpi?

Here is an audio wiring with the filter from @Rodocop.

He says:

If you aren't using the filter your purple wire from the GIPO will go directly to the volume wheel. then everything else will be the same.
