Helder's AIO Board PWM audio

[GameBoyMaster]

I recently purchased a AIO motherboard from helder a bit ago and I read on the page for the AIO 2.2A that you needed to program the config.txt to use PWN audio and I was confused because I don't know what the config.txt file and I don't know how to configure it, I also have the AIO 2.2 not 2.2A so I don't know if this applies to both of them

There is a complete section for support for Helder products....

It doesn't matter with version of Helder AIO board you have....
To enable the audio is the same
(he does have instructions in his support section)

NB: config.txt can be found of the root of the SD Card which has Retropie installed...
(It can be accessed via terminal or by connecting the SD card to a PC/laptop)

Here is the exact line that needs to be added to the config.txt. just add it to the end. Just finished a helder 2.2 today!

dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4

/boot/config.txt
