          @josephchrzempiec At least and as I always say ... use I2S rather then PWM. The PWM sound lacks of clearness and it always brittles with hisses and pops. And you don't need two speakers because the Adafruit I2S mixes stereo channels down to own speaker output. So you have left and right audio channel together in one speaker.

          I made good experince with my little foldable Popeye Pie.

            @cyperghost I was under the impression that Pi zero doesn't have I2S that you can access without using the USB.

            I've gone for PWN audio as I'm using the USB to wire the controls in.

              @monstermadeofman You can use I2S even on a Pi Zero :) You just have to use the Hifiberry overlay and you are ready to go. The sound is more powerfull and 100% clear. You just hear one pop if the AMP is gonna activated and deactivated. In idle (in the ES game selection menu) is 100% NO noise! Follow the link to my build I made for month. In the last posting is a picture of the wired I2S DAC.

                Ahh i see. I'm doing a GBZ build and there is no room in there for that haha.

                I'm PWM audio and to take out the hissing the board I'm waiting on has the filtering plus some nice little ferrite beads to take away a lot of noise

                  @monstermadeofman Sorry I didn't get you. The I2S device from adafruit got the same size as the common PWM amps :)
